Inconsistencies with Honour Resistance

Been running several level 80 Trial of Sekhemas. I've succeed several times so this several times but I've observed some things and after discussing with a few other friends that run it consistently, I think there are some attacks in the trial that either ignore honour resistance or honour resistance isn't working as literally as it reads.

With 75% honour resistance, I've taken damage from spike floor traps that would deal ~1800 damage to my armor/evasion character but the honour loss will be negligible by comparison. Taking a slam from the big skeletons specifically on the fourth floor can deal similar damage than this and take much larger chunks out of the honour bar (from ~2k down to 200). These were observed in the same run, with no boosts to monster/trap damage or any changes to my armor or honour resistance.

Again I've succeeded in completing the trial several times but maybe look and verify if there are some outliers with what is or is not working with honour resistance.
