Couple questions about demons and magic paths

[Gregstrom]

The big weaknesses of demons:
1: Banish. MR 12 takes some of the sting off this, but by no means all.
2: Various weapons have x3 damage against undead/demons. Say 'ouch'.
3: Cleansing Water and a couple of other spells specifically damage demons (and maybe undead) without MR checks.

Blood/Death = access to lots of vampires. Having both paths is pretty strong, as you can slip sideways to Astral and Earth easily from Death and you have a shot at the Blood uniques etc. Of course, it helps to know what minor paths you get with them.
