Titan Quest Anniversary Edition — Achievement Walkthrough

The first real objective of the campaign. Clear the satyrs threatening Helos and the achievement pops as the village quest resolves. Unmissable on a normal playthrough — you cannot progress past the opening region without doing it.

A multiplayer achievement: join or host a co-op game so that at least one other player is in your party. Hosting your own game and having a friend (or a second Steam account on the LAN) join is the quickest route; public lobbies also work. It only needs the party to exist, not to accomplish anything.

Part of the main quest chain in Greece — the Spartans set you a task before they let you through. Follow the quest marker and finish it; the achievement is unmissable if you complete the campaign.

Polyphemus is a named campaign boss in the Greek act. Progress the main quest until you reach him and kill him.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

A main-quest boss encounter in Greece. Gorgons are dangerous at close range, so ranged characters have an easy time and melee characters should stay mobile.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

The Minotaur Lord is a named boss on the Greek storyline. Reach him through the main quest and kill him — unmissable if you finish the campaign.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

A quest objective rather than a kill count: follow the library quest to its conclusion. The name is a joke about the insects involved, not a reference to a software bug.

A named group encounter on the campaign path. Because it is a pack rather than a single enemy, area-of-effect damage and anything that slows or stuns is worth more than single-target burst here.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill.

Nehebkau is a named campaign boss in the Egyptian act. Reach it through the main quest and kill it.

If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

A named boss on the Greek storyline. The achievement name is a Thermopylae joke; the fight itself is a standard campaign boss.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

Artifacts are crafted at an Enchanter NPC (found in most towns). You need the artifact's formula plus every reagent it lists. Lesser artifacts are the cheapest tier and their formulae drop constantly in the first act, so this usually happens naturally — hand the formula and the reagents to an Enchanter and pay the gold cost.

The Chimera is a named boss encountered along the campaign.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

This one has to be found as well as killed, which means it is off the critical path. Explore the desert region thoroughly rather than following the quest marker straight through. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

A main-quest objective in the Chinese act — survive and complete the defence sequence at the Great Wall. Unmissable on a full campaign run.

A named boss encountered in the Orient portion of the campaign.

If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

A story beat in the Chinese act: reach the Yellow Emperor as part of the main quest. Talking to him is all that is required.

Titans are the campaign's headline bosses. You will fight one as part of the main storyline, so this unlocks on the way to finishing the game.

Once a relic or charm is socketed into an item it is normally stuck there — but a Remove Relic scroll (sold by caravan/merchant NPCs and dropped as loot) pulls it back out intact. Buy one, use it on any item that already has a completed relic, and the achievement pops.

A named NPC you have to locate. Follow the quest that mentions her rather than rushing the main path. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

The Graeae are a named encounter on the Greek path.

A story milestone in the Hades content — cross the river Styx as the main quest directs. Unmissable if you play that storyline through.

Reach the Elysion area during the Hades storyline. Simply arriving there is enough.

This is the one Greek achievement you can lock yourself out of in a given playthrough: Shadowmaw has to die on Normal difficulty while you are still in the Greek act. Do not move on to Egypt until you have found and killed it. Because it is off the main path you will need to explore Greece's side areas rather than following the quest marker. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Complete the Ragnarok/Atlantis-era Hades expansion campaign to its end. This is a full act of content, not a single fight — play it through on any difficulty.

You need a bow build with a piercing/pass-through effect so a single arrow travels through a line of enemies. Line yourself up with a tightly packed column of weak trash mobs — corridors and bridges make this far easier than open ground — and fire down the line.

Relics drop in pieces; a relic is 'assembled' once you collect all of its charges and it becomes socketable. Fifty completed relics is a long-haul cumulative goal — it comes naturally if you play multiple difficulties, since higher difficulties drop relics constantly. Do not sell relic fragments.

Found inside the Hades content. Open the treasure vault when you reach it. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Steam hides this achievement's description, and we are not going to guess it from the name. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

A progression marker for the Ragnarok expansion — travel to the northern lands. Unmissable once you start that act.

Charms are the low-level counterpart to relics: they drop from beasts and complete once you gather all their charges. Fifty completed charms accumulates over a long playthrough — hold on to charm fragments instead of vendoring them.

A specific quest item in the Norse content. Follow the quest that asks for it. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

A pet-build achievement: you need three wolf companions and a nymph summoned at the same time. That means investing in the summoning line far enough that the wolf skill spawns three of them, and having the nymph skill unlocked as well. Any character with the relevant mastery can do this — a cheap second character built purely for summons is a common way to grab it.

Talos has to be found as well as killed, so it is not on the direct quest path — explore rather than beeline. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

A story beat rather than a challenge. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Complete the base campaign from Greece through to its final act. Play on Normal for the fastest clear; difficulty does not matter for this one. Almost every story-boss achievement on this list unlocks along the way.

The middle artifact tier. Greater artifacts need a Greater formula plus reagents that include lesser artifacts you have already crafted — so the crafting chain is cumulative. Keep every artifact you make rather than equipping and forgetting them, and check Enchanters in every town for formulae.

Set items share a set name in their tooltip and grant bonuses as you equip more pieces. You need five pieces of the same set worn at once. Sets drop across difficulties, so this usually lands on a second or third playthrough — check vendor stock regularly, since merchants restock set pieces.

An optional named enemy you have to seek out. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill.

Steam does not publish a description for this one and we will not invent a trigger. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

An optional named boss. Undead bosses lean on cold and life-drain damage, so resistances matter more than raw damage here.

A major named boss. Expect heavy elemental damage — top up your elemental resistances before engaging.

A late named boss encounter.

If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

Trivially easy on a fresh character if you are careful: the very first enemies die in a couple of hits and level 2 arrives within minutes. Play at range if you can, do not let anything touch you, and if you take a scratch just delete the character and start again — you have lost two minutes.

A single hit for six figures. This needs an endgame character on Legendary with a heavily invested damage skill, damage-boosting gear, and — critically — a target with low resistance to your damage type. Big slow single-hit skills scale better here than fast multi-hit ones, and buffs that multiply a single strike are what push it over the line.

You need a legendary-tier (purple) item and the means to improve it, which puts this firmly in endgame territory. Legendaries drop mainly on Legendary difficulty, so this is not something to chase on a first playthrough. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Tartarus is the endless-wave endgame mode. On Normal it is the gentlest version, but it is still a long fight — bring a large stock of potions and a build that can handle continuous packs rather than single targets.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

Plague is a spreading damage-over-time skill — it jumps from an infected enemy to nearby ones, so the count climbs on its own if the pack is dense enough. Cast it into the middle of a large tightly-grouped crowd (higher difficulties spawn bigger packs, which makes this much easier) and let it propagate. Investing in the skill's spread radius and duration is what turns a pack of eight into fourteen.

Ten seconds is far longer than a base stun, so you need stun duration stacked from both a skill that applies a long stun and gear with stun-duration modifiers. Bosses and heroes usually have stun resistance, so test it on ordinary trash mobs instead.

Has to be found as well as killed. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

A pure time investment. Levelling slows down hard past the 60s, so the practical route is finishing all three difficulties on one character rather than grinding a single area. Epic and Legendary give vastly more experience per kill than Normal — do not try to grind level 80 out of Normal difficulty.

You need the Phantom Strike skill and six enemies inside its area when it lands. Find a dense pack — corridors, spawn clusters and higher difficulties all help — and put points into the skill's radius so the hit covers the whole group.

Hidden on Steam with no description published. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Battle Standard normally allows one active banner. The straightforward way to see two at once is co-op: have a second player with the skill plant theirs while yours is still standing. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

A no-death run of the whole Normal campaign. It is not a hardcore mode — one death simply invalidates the attempt for that character, so you can keep playing, you just have to start over for this achievement. Practical advice: overlevel slightly, keep resistances capped, always carry full health potions, and retreat the moment a pack surrounds you. Ranged and summon-heavy builds are far safer for this than melee, because most deaths come from being swarmed at close range.

The top artifact tier. Divine formulae require greater artifacts as ingredients, which in turn required lesser ones — so this sits at the end of a long crafting chain and is realistically an Epic/Legendary-difficulty goal. Bank every artifact you craft.

One cast, ten kills. That means casting it into an area already full of low-health trash rather than at the start of a fight — soften a big pack first, then cast and clear. Higher difficulties help because packs are larger.

You need the Colossus Form skill active when Polyphemus dies. Plan the fight: bring him low, then activate the form and land the killing blow while it is still running. Requires a character with access to that skill, so if your main cannot use it you will need a second character to come back for this one.

Mana burn is a specific gear/skill modifier — you need a source of energy-burn damage, then a target with a large enough mana pool to absorb 2500 worth. Caster-type enemies and bosses have far more mana than trash mobs, so use a boss as the target.

Normally you pick a second mastery at level 8 and become a hybrid class. For this you have to finish the entire Normal campaign with only one. It is very doable — a single mastery means all your skill points go into one tree, so your core skills are stronger than usual — but you lose the safety net the second tree provides. Pick a mastery with its own defensive or healing options rather than a pure glass-cannon one.

Ten separate characters, each a different class combination, each at level 10 or above. Level 10 arrives quickly — well under an hour per character if you rush the opening region — so this is a patience achievement rather than a hard one. Note that the class name is set by your mastery choices, so make sure no two characters share the same pair.

Strictly co-op: healing yourself does not count. Take a healing skill, play with at least one other player, and let the total accumulate. A long co-op session with a friend who takes plenty of damage is the fastest route.

Warfare must be one of your two masteries when you finish Legendary. As with the other mastery clears, the same character has to have already cleared Normal and Epic.

A hidden treasure in the Norse content. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

The Epic-difficulty version of the endless-wave mode. Resistances matter far more here than on Normal — Epic applies a flat resistance penalty, so cap your resistances before attempting it.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

The Outsider summon has to reach skill level 20, which means heavy investment plus +skill bonuses from gear. Stack items that add levels to that specific skill or to its whole mastery — hitting 20 through raw skill points alone is not usually possible.

You need a mind-control/charm skill and six enemies affected simultaneously. Invest in the skill's duration so early conversions have not worn off by the time you convert the last ones, and cast into a large pack rather than picking off stragglers.

One of nine mastery-specific Legendary clears. 'As a Defense character' means Defense must be one of your masteries. Legendary is the third difficulty, so you have to clear Normal and Epic on that same character first. Resistances are the whole game on Legendary — the difficulty applies a large resistance penalty, and characters die to elemental damage far more often than to raw hits. Cap them before worrying about damage.

Dream must be one of your two masteries when you finish Legendary. Same requirement as the other mastery clears — a full three-difficulty run on that character.

A pet build, played to the letter: your summons have to do essentially all the killing across an entire Normal campaign. Fewer than 100 personal kills over 30 hours means you should almost never attack — invest everything into summons and buffs, and be careful with damage-over-time and retaliation effects, which can credit kills to you without you ever swinging. Start this on a fresh character; you cannot un-kill things.

Cumulative on one character across all difficulties. It arrives naturally if you take a character through Normal, Epic and Legendary — no need to grind a farm route specifically for it.

The hardest version of the endless-wave mode, on the hardest difficulty. Attempt it only on a fully geared endgame character with capped resistances — the wave format means there is no safe moment to recover, so sustain matters more than burst.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill. If you die you respawn at the last rebirth fountain with your gear intact, so a failed attempt costs you time, not progress.

Hunting must be one of your masteries at the point you finish Legendary.

The same no-death rule as the Normal version, but on Epic — where enemies hit far harder and you carry a resistance penalty. Play cautiously: keep resistances capped, never fight a pack you have not pulled apart, and treat every named enemy as a potential run-ender.

You need a confusion/fear effect that scatters enemies, applied to ten at once. Cast into the densest pack you can find and invest in the skill's radius and duration.

An entangle/root effect on ten enemies simultaneously. Radius and duration investment is what makes the count reachable — cast into a large pack, ideally somewhere enemies funnel together.

Nature must be one of your masteries when Legendary is completed. Nature's summons and healing make it one of the more forgiving masteries for a Legendary run.

Hidden on Steam with no published description. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

Thirty seconds is much longer than a base snare, so you need duration investment plus repeated application — and a target that is not immune. Ordinary trash mobs are far better test subjects than bosses, which usually resist crowd control.

Twelve enemies asleep at once needs both a wide-area sleep effect and a big pack. Sleep usually breaks on damage, so do not attack while you are stacking the count.

A named boss in the Chinese act.

Bosses in Titan Quest hit hardest with one or two signature attacks, so the reliable approach is the same every time: cap the relevant resistance on your gear before the fight, keep moving so telegraphed slams miss, and bring health potions plus an escape or crowd-control skill.

Earth must be one of your masteries when you complete Legendary.

Storm must be one of your masteries when you complete Legendary.

Rogue must be one of your masteries when you complete Legendary.

Spirit must be one of your masteries when you complete Legendary.

The hardest achievement on the list: an entire Legendary campaign without dying once. Do it on a character that has already cleared Epic and is fully geared — going in underlevelled is how runs end. Cap every resistance, keep a movement or escape skill on your bar at all times, and disengage rather than trying to finish a fight that has turned.

A speedrun: Normal, Epic and Legendary on one character inside 20 hours of tracked playtime. That means skipping side content entirely, running past everything that is not blocking the path, and using portals aggressively. It is worth planning the route in advance and watching a run before attempting it — the time limit leaves very little slack for exploring or dying.

Hidden on Steam with no published description. The exact trigger is not confirmed in the Steam description, so we have not guessed it — check a community guide or the in-game hints rather than trusting an invented answer.

A four-player co-op achievement — you plus three others, all inside the Rally effect when it goes off. Organising four people is the hard part; the cast itself is trivial. Group everyone tightly before casting so nobody falls outside the radius.

500,000 kills. Unlike Hercules this is not something a normal three-difficulty run will finish — it is a long-term account goal that accumulates over hundreds of hours. Area-clear builds rack it up much faster than single-target ones.

A conversation, not a fight — speak to the Yellow Emperor when the quest brings you back to him.

Rune is the Ragnarok expansion's mastery, so this requires that expansion. It must be one of your two masteries when Legendary is completed.

Requires the Eternal Embers expansion. You need every piece of one of its sets equipped at once — a full set, not five pieces. Set pieces drop across the expansion's content and restock at merchants, so check vendors regularly rather than relying on drops alone.

Every quest in the Eternal Embers expansion, main and side. Because side quests are easy to walk past, check your quest log against the region you are leaving before you move on — and clear each area's optional content before advancing the main story.

The easier half of the Bao pair — any monster item from his stock counts, not specifically an infrequent one. Check his inventory whenever you pass through.

A collection of developer-tribute enemies scattered across the game, all of which have to be killed. They are optional and hidden away from the main path, so this needs deliberate hunting rather than a normal playthrough.

Neidan is the Eternal Embers mastery, so this needs that expansion. It must be one of your masteries when Legendary is completed.

The easier half of the Bao pair — any monster item from his stock counts, not specifically an infrequent one. Check his inventory whenever you pass through.

A no-death clear of the whole Eternal Embers expansion. Bring an already-geared character rather than levelling through it, keep resistances capped, and treat every named enemy as a run-ender — the expansion's content is tuned for characters who have finished the base campaign.
