Update yaaaay!.
Wait no I wasn't here to say that. Well, I guess more people will put a better report right after, but I gotta say it now. Apparently, to nerf the leech spells, you put them down to +0. Well, it seems that at least vampirish night doesn't do any damage at all. I assume the idea was to make the attack only based on the base stat alone, but you actually reduced it's damage to 0
