I've been playing the mod for a while now and one thing that was bothering me where stuff like certain boss enemies only being able to be killed by the player and not other ally npcs.

I'm not sure about Gravemind but Didact, Tartarus and the Prophets in particular. It's very frustrating losing many allies in this situation because they don't even deal any damage to them.

This is not the case with Guilty Spark so it would be very appreciated.if the same goes for the other bosses.
