Dang, I'm annoyed that it's a multi choice though, one thing I really liked doing was parking the wisp at certain spots. You could escort them through a ritual and stay on the other end of it, trigger the ritual, and half the mobs would get possessed.
You could also park a bunch of the splitting wisps at the map boss, go clear the rest of the map to gather more, and escort those to the boss and power it up with like 20 wisp mods.
Also sometimes the wisp group would split and half of them would go one way and the other half would go the other way, which I guess would be fixed in this patch by the other change making them target the nearest rare instead of a predetermined one.
