Bug or intended 2nd boss Trial of Sekhama (or how its spelled)

So I was doing my 4th trial for the last points

I am 2967 hp
85% armour (16464)

I had 5968 honour left
and 75% honour resistance

I killed the 2 bosses in 7-10 seconds and move to the edge of the room

At that point I was 100% hp and 5800/5968 honour left

I even had the boon that said something like (if you die you get 30% life 50% honour or something like that).

then BOOM said the screen and I was INSTANT dead

The death box read that I had died in room 1 of the cunning or something like that?

Is this a bug?
Is it intended and due to some of my resistances not being maxed out?

Anyone tried the same?

Cant be borthered to do 30 minutes of trials again before I understand why I just wiped like that a full life and honour after a boss had already died

Noone tried this?
