Warrior is one of the tougher classes in the game I think. I haven't rolled one yet, but I have read a lot of what people have to say about it. I rolled a softcore Merc and Witch this season. I just got the first two ascendancies on my merc last week. Hoping to get him to endgame by the end of this coming week.
I don't even know what that means xD must be something after act 2
Yes, the first ascendency trial of sekhemas becomes available in Act 2.
