Kyrian
Dîme spoliatrice - Interesting ability that applies a dot to your target, if your target dies while the dot is active you generate 5 Soul Shards. If they survive, the cooldown is refreshed. There are numerous scenarios where this spell could be very useful as you can end up having very high uptime on this dot. You can also gain quite a few Soul Shards over the chorus of an encounter or even a full dungeon.
Invocation de régisseur - Not very interesting ability, but can situationally be useful as well.
Necrolord
Trait de décimation - An "execute-style" ability that buffs your next 3
Incinérer casts.
Trait de décimation and the bonus to
Incinérer both increase the lower health your target has. This is looking to be the "go-to" option for raiding as of right now.
Chair recomposée - An absorb on a 4-second channel, buffed by channelling near a corpse. This ability isn't game-breaking as Warlocks already have quite a few damage reductions and shields available, but it does add another layer of defensiveness that can prove to be useful in a lot of scenarios.
Night Fae
Pourriture d’âme - Alternative AoE ability that could prove to be good. However, with this being capped to 4 targets it's not very likely you will end up utilizing the
Drain de vie part of this ability.
Forme d’âme - Kind of an interesting mobility option that may end up being useful, but with already having
Ruée ardente,
Cercle démoniaque and
Porte des démons available it's hard to say how useful this is actually going to end up being. Very situational.
Venthyr
Catastrophe imminente - This is an interesting ability as it provides you with a spell that applies either
Malédiction des langages or
Malédiction de faiblesse to all enemies within 12 yards of the target. This could prove to be very useful in a number of mythic+ pulls to reduce the damage dealt by set pack.
Porte des ombres - This teleport ability can be very useful both in Mythic+ and in raids. It can be used to skip difficult packs of mobs or to avoid raid mechanics. This can prove to be a very strong ability in a lot of content.
