Defeating Nightmare and Void, a mod by Samihamer1 to make Nightmare King Grimm and Pure Vessel slightly more challenging by having them team up.

Not too hard overall but it's pretty fun to try to deal with both of their attacks at once. I didn't quite realize you could stand in Pure Vessel's foot when he dives (or maybe it's just been too long since I've done the fight). I'm not too sure how to make it through the third pufferfish phase unscathed except by bouncing on Grimm's head or spamming descending dark.
