The Trialmaster Boss Guide

The Trialmaster is one of the many endgame bosses available in the Path of Exile Endgame. The Trialmaster can only be challenged if the player survives past the 10th Wave of the Trial of Chaos and has the three Fate Fragments to access his arena.

Getting to the boss

At the end of 10 rounds of the Trial of Chaos you have the option to challenge The Trialmaster. You use the 3 fate fragments obtained from defeating the 10th round boss in Trial of Chaos, or trading with other players:

• Cowardly Fate- Drops from Uxmal, The Beastlord during the 10th round.
• Deadly Fate - Drops from the Bahlak, The Sky Seer during the 10th round.
• Victorious Fate - Drops from Chetza, The Feathered Plague during the 10th round.

Blood Wave Whirlwind

Occasionally the Trialmaster spreads his arms out in a mocking manner, before swiftly spinning with his spear causing small crescent blood waves to fire from his spear.
