Still seeing this triggering off on the Aura owner\caster. If I change FACTION(foe) to FACTION(!foe) then nothing happens. Potentially, could still deal with this to make life simpler on the monsters getting attacked (and just heal up the cleric each time for whatever damage they take), but would be great to figure out a means in which it doesn't impact the caster.
Sorry, should mention this is all in 5E, this test was with just the Aura Effects and Ongoing Saves Effects loaded.
