Ebrietas from bloodborne. Forgot how many times I died with her.

Did you play the dungeons in Bloodborne?
Ebrietas is a joke compared to Amygdala in the dungeon where you only have 1/2 of your life.

Don't remember but I did plat the game though.  Did I have to come accross with her in order to plat it?
