Kill them all!
Henzell says...
  1. (L7 summ/necr): Summons 2-6 wraiths and undead "ghost" type monsters around the target. Smite-targeted, but only castable on a monster. In 0.16 and earlier caused sickness when cast unless you worshipped Kikubaaqudgha and passed a piety-in-200 check.
  2. < crate_> anyway if you have haunt sickness doesnt matter anyway < crate_> because you have haunt
