After slaying Gladius, Beast of Night, one of the very next Nightlords you're likely to come across in FromSoftware's new co-op roguelike spinoff Elden Ring Nightreign is Adel, Baron of Night. The Gaping Jaw Expedition you hunt it in is the first of the six additional missions you unlock after beating Gladius, though it's not easier than the other ones you can embark upon by any means.
In fact, I'd say Adel is actually one of Nightreign's harder Nightlord bosses, even if its overall moveset is on the simpler side. It hits very hard and is very mobile compared to some of your other targets in your quest to dispel the Night, but luckily, also has some very pronounced weaknesses and is very punishable once you know how to avoid its most lethal attacks.
