Submission: Met Kalfu (Petro Loa)

I made some edits to reflect your very positive changes. I felt a retainer fixes the issue with having to wait too long. The necromancy was giving certain clans a unneeded power boost. I left the negative drawback of being Infernal only if the retainer burns.
I also edited a way for the retainer to gain life other than from the pool cost of Infernal.
Do you feel this helps the problem? Or do you still feel this needs more changes?
