Sekhemas Glitchy

So I'm cruising along in sekhemas, get the boon for you cannot take damage and then die get 1 shot somehow from Zarohk when I'm not supposed to take damage and my honor is completely full? Make it make sense.

His one shot mechanic (portal at center of arena, have to collect 6 totems) bypasses the no damage boon completely, since it doesn't deal damage and is a flat "fail" mechanic that simply kills you. Really annoying, especially when he spawns totems off-screen so you can't plan your route effectively
