Archfey 21
Celestial 22 + 1 = 23 Decent blaster+healer. If Blade had Hexblade's +Cha-to-hit, this could be my favorite.
Fathomless 23
Fiend 20
Genie 19
Ghost in the Machine 7
Great Old One 21
Hexblade 23
Lurker in the Deep 18
Raven Queen 19
Seeker 18
Undead 21
Undying 12 - 2 = 10 Frankly, I feel like most of its interesting features should be pact-agnostic invocations.
Undying Light 5
