So im trying to convert viviscitude (and to a lesser extent the Tzimisce clan as a whole) and i was wondering if there is actually any problem just dropping them in and switching "blood points" to "vitae" when it comes to costs and adjusting the skills to requiem's roster.

For example, does masquerade's weapon power scale differently than requiem's? Does the damage?

I'm a bit out of my depth in onyx path's arena, being a pathfinder stan and reluctant D&D expert, the world/chronicles of darkness use a very different mechanical style, both in mechanism and the involvement of rules.
