That is, you lose all your mana as a welcoming gift. Particularly the spells added here, because this mod is hardcore. I mean, this could be excused if they were supposed to be more of a side thing, with the clan being less magic-oriented and the spells are just a bonus, but it's the freaking Tremere. I've played what I think was a previous version of it a while back and it had a pretty big problem.
