I was using this Angela in Incursions (Threat Level 5) with the prefights from a 5* Odin.

A few floors in (past 10)... I got effectively one-shot from near-full HP by a Nightcrawler.
I forgot to take a screenshot of the fight stats, but I remember taking 15k damage from his hit, and roughly the same from his Instant Bleed (which the fight stats said)
I recall definitely having the Protection buff active, and there weren't any nodes that would remove or bypass it, so... I'm not sure what happened.
Angela shouldn't be able to lose more than 18% from a single hit, yet she was instantly wiped.
That said, there have been other occasions where I've definitely taken more than 18% damage from a hit even with the Protection buff
...does it interact weirdly with the Odin/Angela synergy?
Has anyone else experienced something similar with this Protection not... protecting?
