We are heading into combat against some Devils as part of the HR AP. Its going to be a Tough!
So as a mesmerist Im going to try the possession spell (from OA) against one of them as its a non native outsider, however if the devils have protection from good on - what if any bonus does protection from good do to prevent this. Would the devil (if it had it) get another save at +2 to avoid? I get protection from evils comments about possession generically, but then references mind affecting spells.
Im actually LN so my assumption is that protection from good would have no affect anyway (but I am interested).
Also could a dispel magic targeted at the devil actually throw me out of the body? Would they need to know it was possessed?
