Combine Kai's Strike/Kai's Smite and replace one of them with "Catching Spirits".


The Symbol of Catching Spirits gives the undead specialist the power to *search undead while in RT*/preserve an undead
target which would otherwise vanish too fast to be searched before RT ends.

So the Symbol is a running symbol and when it is going, if you kill an undead who has a tendency to disappear too fast,
the creature's soul will be unnaturally bound by the magical powers to their body until the Volner searches them. Or the
Volner can search the undead while in physical RT.
