Bodak Death...raise ok?

[RUMBLETiGER]

It is a good idea, but, the duration is just 2 hours a level and some of the spawning windows are the entire next night for energy drain wights and 1d4 days for some creatures.

I'd wait until the shortest amount of time in which the undead would rise and cast the spell, than recast it as many times as possible to reset the duration before the spell wore off.
