Venthyr and Necrolord are potentially not final but still… all of them are kind of nothing special, mostly - “are the numbers big enough?”.
For MW Night Fae heal allies for an essence font bolt which either be close to useless or will mark everyone in a raid with an essence font bolt to then drop a cooldown on them. Raid ability.
Necrolord seems like an usable cooldown depending how much extra it will heal. M+, vivify spam moments in raid.
Venthyr - not sure how active spawns will be but it’s either random or somewhat smart ReM spam. Raid?
Kyrian have a cooldown-alike power to EF which can be handy when Revival is on CD or would dispel stuff. Raid, EF value in M+.
