Hear me out…
The concept would be based on the tapping of mobs essences and using it to heal yourself and your teammates.
Basic mechanics would be based around doing light damage to mobs that translates to healing for you and the party/raid.
Soul Expulsion: Damage over time spell that slowly forces the essence out of the target creating an aura around them that heals anyone in range for X amount. (scale down for number of targets, etc, balance). Stacks up to X time (balance).
Energy Focus: A ‘totem’ type spell, you plant this and it takes the essence you’re tapping from all sources and creates a healing aura around it instead of the targeted enemies.
Essence Transfer: Cast once on a friendly target and a second time on an enemy target. Directly feed essence from the enemy into the target to heal them.
If you target your Energy Focus instead of a friendly unit, you will amplify the healing aura around the Focus.
Self Sacrifice: Allow you to cast your Essence damaging abilities on yourself to heal those around you or feed your Energy Focus.
Charge Focus: Turns off the healing Aura of an energy focus allowing it to store essence.
Discharge Focus: Discharges all stored Essence from your Energy Focus onto the target.
This is just sorta some of what I’ve thought of in relation to this spec idea to give a flavor concept and direction.
I am now accepting flames and insults. Tyvm.
