Indeed, I suspect that is exactly why they made it harder. A free heal on every floor is a pretty big boost.
I wonder if they dealt with the humility loophole. That is, get to level 10 +50 XP to get your first milestone regen, then purchase humility to level up to level 10 and get a full heal for doing so. Effectively two full heals for the price of one. Solution is that humility shouldn't give a full heal if you're already reached your first milestone.
I did not realize that was one of their class abilities. Sorry about that!
Yup, they can't convert but also cannot lose piety. Makes them ideal
worshippers of Glowing Guardian and Dracul whose primary disadvantage is their stingy piety gain and harsh penalties.
