Nexus Clash

Guy Bourgeois Was infected with Defiler poison, than infected with Minor poison by a plague rat, then he was killed. Up until that point, the defiler poison was dealing damage. (I didn't take any actions after getting the minor poison, so I don't know what the stack effect might have been.)

I saw a post on discord that when he died he spawned a skeleton and a shambling zombie.

Upon respawning Guy still has the Defiler poison status effect, but is not taking damage.

seraphs don't take damage from poison due to corpus machina

you'd probably notice 6 damage per action if you were taking damage, and if you were, that'd be the bug

Sorry about the post. In the light of day rereading the log there was no bug.
