The Trial of the Sehkemas is a challenging gauntlet that consists of seven different rooms, each with a unique set of poe2 trade trials and challenges. As you progress, you'll encounter various obstacles, many of which come with negative conditions that hinder your character's abilities. Some rooms might also inflict debuffs, adding to the difficulty.
One key element of this trial is the honour system. Honour is a resource that represents your life pool throughout the entire trial, displayed at the bottom of your screen. Every time you take damage during the trial, your honour will decrease. If your honour reaches zero, you fail the trial and will have to start over. Keep a close eye on your honour, as every hit can make the difference between success and failure.
Once you complete all seven challenges and defeat the final boss, you'll gain access to the Altar of Ascendancies. Here, you can choose your Ascendancy class, which will grant you your first two Ascendancy points, allowing you to begin customizing your character's playstyle with new abilities.
After completing the Trial of the Sehkemas and ascending to your chosen class, you will want to continue progressing and earn more Ascendancy points to unlock additional nodes in your Ascendancy skill tree. To do so, you'll need to complete the Trial of Chaos, which becomes available in Act 3.
The Trial of Chaos is located in the Temple of Chaos, and it is unlocked after you defeat Xyclucian, the Chimera, in the Chimeral Wetlands in Act 3. As with the Trial of the Sehkemas, you'll need to pick up a special item dropped by the boss: the Chimeral Inscribed Ultimatum. This cheap POE2 Currency serves as your key to accessing the Trial of Chaos.
