1) Not sure if this is a bug or intentional: Dracul awards piety for using lifesteal two times per monster (assuming it has blood, of course): when you first hit it with a lifestealing blow, and also if your finishing blow does lifesteal. (Note that if you KO a monster in one blow, then you only get Lifesteal-piety once.) Dracul's Codex entry says "Dracul will give you piety for every XP-valuable monster you steal life from.", which is ambiguous. Is the way it is now intended; is Dracul supposed to give Piety for every lifestealing blow; or is only the first time you lifesteal a monster (or even only the finishing blow) supposed to award piety?
2) My death gaze here is at 25%. Aequitas' health is at 63/348 = just over 18%. Why am I getting a "Death" prediction? Does being Cursed make Death Gaze not work?
Note that the prediction does suggest that I'd remove all of his 63 health, despite my attack being only 40, and Aequitas only having 3 stacks of burning. If the prediction here is accurate, my guess as to what's going on is that being Cursed is removing Death Gaze's "first strike" capacity, but otherwise leaves it working normally.
Also note that my next course of action was to quaff three health potions, then deal the finishing blow. I lost the health I had just regained, meaning the problem (if there is one) isn't that "while the prediction is wrong, otherwise death gaze is worked as expected".
For comparison's sake, here's the second boss I fought in the same dungeon:
Here Death Gaze worked as expected. I was able to kill Bleaty immediately, despite being lower-level and my attack being lower than Bleaty's remaining health.
3) A minor issue: Nowhere in the Gorgon's description does it say that they start with 10% Death Gaze, or that they're immune to Death Gaze. In contrast, the Half-Dragon's description does say that they start with 20% knockback.
