Archanist Question(s)

Actually it's Necrogenesis which heals you based on spell damage and Parsimony that recovers MP based on the spell cast.
I dare say that Parsimony is not an MP drain because it does not gives you a net gain, it was originally meant to halve the casting cost but they were not able to implement it as such in the 1.0 engine

It was half mp cost and mp on hit and both of those are skills not spells.
