Thank you for your report! I'm working on a hotfix to release asap
Healer does not have unique dialogue for when you already have a healer recruited and a second robe... (Mentioning it because fossil does have dialogue for the equivalent scenario...)
The bishop's stab dialogue clearly refers to him being shot with pirate's gun and not stabbed with dagger 48... The bleeding mirror's dialogue can also be updated to fit the gun more but it does make sense in its current state...
A somewhat more major bug: it seems that reviving while poisoned makes the poison damage take away a second revive... (Enemy has to kill you before the poison ticks...)
I tested the scenario you described and this is what happens:
-The enemy hits you, reducing your hp to zero
-The poison deals damage (but your hp are already at zero)
-At this point, you come back to life using a resurrection (only one)
Everything seems to be working correctly, but I'll do more tests in the future
