Quick answer (TL;DR): The Trialmaster is the pinnacle boss of the Trial of Chaos. To fight him you must hold all three Fates — Deadly, Cowardly and Victorious — then clear a 10-round Trial of Chaos and insert the Fates into the door in the final room to enter his Tower. His fight is a fair, heavily-telegraphed duel in two forms (Mace and Unarmed); the only attack that reliably one-shots you is the Sunder ground-slam (and its Timestop version) — dodge-roll those and you survive. Defeating him for the first time awards your final Ascendancy points, and every kill drops a guaranteed Trialmaster unique plus a chance at corrupted Inscribed Ultimatums. If your build can't survive the Sunder, a carry or boost gets you the kill, the points and the loot without the wipes.
If you have farmed Trial of Chaos all the way to 10 rounds and finally have three Fates burning a hole in your stash, there is exactly one thing standing between you and your last Ascendancy points: the Trialmaster. He is one of the most-searched bosses in Path of Exile 2's 0.5 Return of the Ancients update for a simple reason — players keep getting deleted 0.1 seconds into the fight and have no idea why.
This guide is the boss fight itself, end to end: how to unlock him, every attack in both of his forms, the exact defenses you need to stop the one-shot, what he drops, and whether the farm is worth your time.

Who is the Trialmaster?
The Trialmaster is an endgame boss found in the Trial of Chaos — one of PoE2's two Ascendancy trials (the other being the Trial of the Sekhemas, whose final boss is Zarokh, the Temporal). Lore-wise he was once Ixchel, a human member of the Order of the Djinn, before becoming Chaos's tireless tormentor of aspirants (source: PoE2 Wiki).
Mechanically he is a repeatable pinnacle encounter: the first kill finishes your Ascendancy, and after that he becomes a currency-and-unique farm. He is widely regarded as a well-designed boss — slow, readable attacks with clear tells — which is exactly why the players who die to him die to the same one or two moves every time.
How do you unlock the Trialmaster fight?
You need three things, and you need them together: the three Fates and a completed Trial of Chaos to spend them in.
The Trial of Chaos is entered with an Inscribed Ultimatum, which any monster can drop from Act 3 onward. The area level of the Ultimatum sets how many rounds you run, and only the 10-round version matters for the Trialmaster:
| Inscribed Ultimatum area level | Rounds | Drops a Fate? |
|---|---|---|
| 39–59 | 4 | No |
| 60–74 | 7 | No |
| 75+ | 10 | Yes — round 10 boss drops a Fate |
In a 10-round run, rounds 4, 7 and 10 are boss rounds, and the round-10 boss always drops one of the three Fates (source: Maxroll). Collect all three:
- Deadly Fate — "Fight enough battles, and it becomes all but inevitable."
- Cowardly Fate — "The ignoblest of choices."
- Victorious Fate — "There is always a chance, however small, that you might actually succeed."
Per the PoE2 Wiki, each Fate "can be placed in the door at the end of the Trial of Chaos to challenge the Trialmaster." Clear one more 10-round Trial while holding all three, and a door appears in the final reward room (near the Ascension Shrine) — insert the Fates to open the Trialmaster's Tower.
Buy or farm the Fates? You can purchase Fates outright on the Currency Exchange — players report roughly a Divine Orb for a set — and skip the grind to the fight. The cheaper path is to farm 10-round Trials anyway: you bank Soul Cores, keys and drops worth ~0.25–1 Divine per run and the Fates fall out naturally. Either way, hoard a few sets before your first attempt so a death doesn't cost you a 30-minute farm.
The Trialmaster's attacks — every move and how to dodge it
The fight is completely isolated: none of the affliction modifiers you picked during the Trial carry into the Tower, so you walk in at full strength. You cannot pause once it starts. He cycles between two forms; here is every ability, by form (source: PoE2 Wiki).
Mace form (the dangerous one)
| Attack | Tell | How to handle it |
|---|---|---|
| Sunder ("Be crushed!" / "Fall before me!") | Slams the ground, releasing a red Sunder shockwave | THE one-shot. Dodge-roll the instant the mace comes down. He often opens with it and repeats it frequently while armed. |
| Timestop Sunder ("Ultimatum!" / "Entropy!") | Freezes time, teleports and slams 3× | Three delayed Sunders land in sequence — pre-roll and keep moving; do not stand still when time resumes. |
| Mace Swipe | Two quick swings, can turn mid-attack | Roll out to the side; don't expect him to face his start position. |
| Bloodburst ("Be obliterated!") | Plants mace in ground, channels a large area | The zone explodes with blood when he yanks the mace out — leave the area before the pull. |
| Cyclone ("Rip and tear!") | Spins 6–7 times, drifting toward you, firing shockwaves | Kite at range; the shockwaves are random, so keep lateral distance. |
| Mace Throw ("Chaos aid me!") | Hurls mace into the ground near you | It pulses an expanding Physical nova; reposition away from the embedded mace. Transitions him to Unarmed form. |
Unarmed form
| Attack | Tell | How to handle it |
|---|---|---|
| Tri-Elemental Mortar | Lobs three projectiles | Each hits a small area for Fire/Cold/Lightning — spread them out, don't cluster the impacts. |
| Trialmaster's Heart ("Be still!") | Drops his heart, tethering nearby players | Moving away severs the tether for Physical damage + stun — destroy the Heart or stay tight, don't sprint off blind. |
| Blood Projectile ("Surge of Chaos!") | Large red orb bouncing off walls | It explodes on impact and can fork off walls — watch the ricochet, not just the launch. |
| Timestop Projectiles ("Ultimatum!") | Freezes time, casts 3× | Three delayed Blood Projectiles — pre-position in open space. |
| Mace Recall ("Chaos aid me!") | Recalls the mace | Ends the Mace Throw pulses and shifts him back to Mace form — re-center for the Sunder. |
The single takeaway: ~90% of Trialmaster deaths are the Sunder (and Timestop Sunder). It is slow and loudly telegraphed; the only reason it kills is input lag or panic at fight start. Learn to dodge-roll on the mace raise and the fight becomes routine.
What defenses do you need to survive?
The Trialmaster is roughly 10× tankier than the Trial's round bosses, so expect a longer fight — which means more chances to eat a Sunder. Build to survive one big hit and you win.
- Cap your elemental resistances (75%). His Tri-Elemental Mortar and elemental tells melt under-capped characters fast.
- Carry a real life/ES buffer. Players clear him comfortably at roughly 2k+ Life and 2–3k Energy Shield; the goal is to survive a clipped Sunder, not to facetank it.
- Movement speed and a dodge layer. A reliable dodge-roll and ~30%+ movement speed turn the Sunder from lethal to trivial.
- Hug the walls. Mobalytics recommends fighting near the arena edge so his ground effects don't blanket your dodge space.
- Don't over-invest in Chaos res. Despite his Chaos theming, his big hits are Physical (the Sunder) and elemental (the Mortar) — cap your elemental resists and build EHP rather than chasing high Chaos resistance for this fight specifically.
If you are getting one-shot before you can react, it is almost always the opening Sunder landing during a stutter. Pre-roll the moment the fight loads and keep your cursor on open ground.
Trialmaster loot — every unique drop and is the farm worth it?
Every Trialmaster kill guarantees one of his unique items, and his rewards only appear after you are kicked out of the arena (they stack on top of your cumulative Trial rewards). The guaranteed-unique pool includes:
| Unique | Type | Why it matters |
|---|---|---|
| The Adorned | Jewel | Massively amplifies the effect of Corrupted Magic jewels — a build-defining chase item. |
| Mahuxotl's Machination | Shield | Huge Armour/ES scaling and boosts socketed Soul Core effects. |
| Everlasting Sacrifice | (varies) | Rotating high-value Trialmaster unique. |
On top of the unique, he has a chance to drop corrupted Inscribed Ultimatums (a harder, higher-reward re-run) and the Trial itself yields Soul Cores — the exclusive Trial of Chaos currency you socket into gear in place of runes.
Is it worth farming? As a sustained money farm, the Trial of Chaos pays ~0.25–1 Divine per 10-round run from Soul Cores, keys and drops, with the Trialmaster as the cherry on top when you hold Fates. It is a targeted unique farm and an Ascendancy gate more than a top-tier raw-currency strategy — for pure currency density, juiced Expedition and T15+ maps (see our PoE2 currency farming guide) out-earn it. Divine value floats around 100–130 Exalted in 0.5 — always confirm the live rate on poe.ninja before you sell.
Should you carry or buy a Trialmaster kill?
Here is the honest split. If your build can already survive a Sunder, kill him yourself — he is one of the most satisfying duels in PoE2 and the Fates are cheap. But two groups are better off buying the kill:
- You need the Ascendancy points now. Being stuck at 6 points while everyone else has 8 is a real power gap, and re-farming Fates after each wipe burns hours.
- You're hunting a specific unique (The Adorned, Mahuxotl's) and don't want to gear a character around surviving him first.
A Trialmaster carry clears him on your character so you keep the loot, the Ascendancy points and the unlock — no wipes, no re-farming Fates. And if you'd rather power through him yourself, the fastest route is simply more damage and EHP, which means currency:

Frequently Asked Questions
How do you unlock the Trialmaster in PoE2? Hold all three Fates — Deadly, Cowardly and Victorious — and complete a 10-round Trial of Chaos (entered with an area-level-75+ Inscribed Ultimatum). A door appears in the final reward room; insert the three Fates to open the Trialmaster's Tower and start the fight.
Why do I get one-shot instantly by the Trialmaster? It's almost always his Sunder ground-slam landing at the very start of the fight, often during a frame stutter or input-lag spike. The hit is large and Physical. Pre-roll the moment the arena loads, cap your elemental resists and carry a solid Life/ES buffer so a clipped Sunder doesn't delete you.
Does the Trialmaster deal Chaos damage — do I need Chaos resistance? Despite the "Chaos" branding, his heavy hits are Physical (Sunder) and elemental (Tri-Elemental Mortar). Cap your 75% elemental resistances and stack effective HP rather than over-investing in Chaos resistance specifically for this fight.
Do the Trial of Chaos afflictions affect the Trialmaster fight? No. The Trialmaster arena is completely isolated — none of the negative modifiers you chose during the 10 rounds carry into his Tower, so you fight him at full strength.
What does the Trialmaster drop? A guaranteed unique every kill (The Adorned, Mahuxotl's Machination, Everlasting Sacrifice and others), plus a chance at corrupted Inscribed Ultimatums. Rewards appear after you're ejected from the arena. The Trial itself also drops Soul Cores.
Is killing the Trialmaster how you get your last Ascendancy points? Yes — defeating the Trialmaster for the first time grants your final set of Ascendancy points via the Trial of Chaos path. You can alternatively finish the Trial of the Sekhemas and beat Zarokh instead; you don't have to do both.
Can you buy the Fates instead of farming them? Yes. The three Fates are tradeable on the Currency Exchange (roughly a Divine for a set). Many players still farm 10-round Trials because the Fates drop for free alongside ~0.25–1 Divine of other loot per run.
