I like the alterations myself. I'm not sure 'boss killer' would be desirable either considering if you have someone who specializes in taking out BBEG there is a big incentive for the GMs to play around countering that person so fights don't end instantly. A couple of negative levels start hitting those huge -X penalties to hit on things rapidly causing attacks and spells to be worthless quickly is too threatening to not have a counter too if you have a huge villain.<br/><br/>I can offer an alteration to your proposed Connoisseur of Life alteration. Remove the 'can't heal energy drain/ability drain' and alter it so all 'HP Drained from Methu's Energy Drain or ability damage from bite (or whatever it is you are using to cause that) is considered Vile Damage'. It keeps them from bouncing out of the aura and instantly curing the hp damage, minions are dead from the energy/ability drain anyway, and bosses that can't heal ability drain are going to either be immune to it or have temp stat points to keep it from gimping them anyway. The Vile damage means even if they get out of range they'd need to consecrate or hallow an area to heal it which is more complicated than getting out of the 60' aura. It also makes it harder for other demons to fight him since they'll have to seek out a way to get hallow or consecration.
