Anyone looking to achieve their third character Ascension in must first beat a powerful boss — Ashar The Sand Mother. This massive scorpion is a challenging opponent you face during the Trial of Sekhemas challenges, which test your character's might to see if they are worthy of Ascension. You'll need to overcome Ashar to unlock unique specializations for your character's class from a new Ascendancy.
The Trial of Sekhemas can only be found when you defeat the boss Balbala the Traitor during the game's main story quests. Once you beat this enemy, they will drop the Balbala's Barya item, which you can take to the Trial of Sekhemas node on your map. Placing the Balbala's Barya item into the altar at the Trial of Sekhemas location unlocks the area's challenges, including its Ascendancy bosses.
You have to defeat two other Ascendancy bosses in the Trial of Sekhemas before you have a chance to face Ashar. The Trial of Sekhemas in demands that you accumulate a unique resource called Honour from defeated enemies in a specific Trial tier. You also need a Djinn Barya of at least Level 60 to access the arena in which Ashar spawns.
Honour acts as both a currency and a health resource in the Trial of Sekhemas floors. If you lose all your Honour, you will fail that Trial and be unable to face an Ascendancy boss.
Getting enough Honour on the third floor of the Trial chambers will allow you to open a path to Ashar's boss room. Before you take on Ashar the Sand Mother, you should make sure to accumulate more Honour than you need to unlock the stairs to the boss. Since Honour is tied to your overall health, the more you have before facing Ashar, the longer you will survive through the boss fight.
The final boss of Path of Exile 2's Trial of the Sekhemas is Zaroch The Temporal, the strongest enemy you could ever challenge during your journey.
When you're ready, interact with the altar in the Trial of Sekhemas on its third floor once you have enough Honour. This will open up the door
