banishment

[arpade]

ive practiced the empower (*gasp*). I havent tested it against summons yet, but in its desc, it sais it works against undead. This does not work. the result is "this creature is in its natural plane". either the help file, or the empower is incorrect.

Works against necromancer undeads. Whether it should work against all undeads or not, is open to discussion.

Maybe it will be better to rebuild a bit spell?
Let banishment force followers to forget where are thier master for a period of time. There will be the same result and no problems with other undeads and summoned creatures.
