Spirit Shift is an animus so it can be cast by Kaya on another beast, right?
So, a pureblood goes ghostly, runs through the enemy's line and ends up next to their caster. Then Kaya casts Spirit Shift on the pureblood and teleports herself to within 2" of the beast. Then she feats and teleports her three other feral warp wolves in to shred the enemy caster, right?
Is this scenario doable?
