Re: The Wild Hunt
This. Definitely this. But:
Let them be (Stunned).
But when they fall behind (for whatever reason), they vanish away, back to their . . . well, whereever it is they come from
This maintains the overall impression that the individual members of the group are eerily synchronized, in their movements; they never become scattered. The vanishing can be IPE since appearing to fade in and out of sight might be part of the SFX.
Then, give the leader of the pack a Continuous Summon, only to call forth the missing ones
The overall SFX is that you can swipe at them and they dissipate, but a few seconds later they're back again, only this time over there somewhere
