Best relic for vitality conjurer?

I’m playing a vitality conjurer… a sort of hybrid with pox and swarm but also savagery. Used deathchill relic for a while with aura for flat vitality damage, upgraded it to scourge which is okay but I don’t feel like I really make use of the granted skill. Now I’m thinking about upgrading to necrosis but I’m not sure that that skill would be worth it. Don’t feel like I need a movement debuff because I’ve got full CoF and none of the resistance debuffs would benefit me. (Why couldn’t Necrosis reduce vitality or bleeding which is at least a decent part of my damage compared to ele, aether, chaos). So how is necrosis compared to scourge or should I just go back to deathchill aura so that I can play with basically only four buttons other than heals that I hit only on bosses/thick hero packs.

Do you have the expansions? Meditation is excellent for that build. I run something very similar.

No, just base game. I’m running basically the same skill setup except traded some points from BoD and SolaelWF (first node) and occultist mastery only 40 to have Wend totem with blood pact.

I’m starting to like scourge strike a bit better now that I have a vitality damage weapon which added ~20% damage by knocking out the conversion to cold. Necrosis gives me nothing but AoE vitality damage and I don’t know how good it is but I wreck mobs pretty well - against big targets I don’t know if the damage is enough to be better than scourge strike. Aether, chaos and elemental RR just seems so out of place for a vitality damage relic.
