[BUG ?] Broken Vampire ?

[foxclear]

I had a Vampire (a Foil one, not sure if it matters). Yet, I tried "feeding" him a holographic card, a foil card, a gold seal, and a purple seal. Some of which were scoring cards, some not (which shouldn't matter considering the wording of the Vampire, but still ...).
Well, that Vampire actually drained a single one of my enhanced cards (can't remember which one, it wasn't even the first. Might have been a Mult card, but can't be sure), the rest he didn't interact with : they kept their enhancement, and he didn't get buffed in return. It was the only joker that interacted with my cards, the rest being adding to Mult
Are those I described not considered as enhancements ? If so, what is an enhancement ? Or is it simply broken ?

Yeah, not every card modification is an enhancement. You can check enhancements in the collection : it's every modification that can be done by using tarot cards. Seals or holographic don't count.

Oh !
Well, thanks for the clarification ! That is certainly lacking in term of description, though. At last I've found something bad to say about this game :D
