idea for a new warlock blast

Leeching Bolt

Dark Invocation

Blast Shape

when using this blast shape the warlock is healed 1 point per dice of damage if it hits a target

only base blast dice are used for this eldrich master and hellfire bonus dice do not apply ( limiting the regen to 22? max or maybe put a cap of 20 if needs be )

as for vfx of this i was thinking a reverse magic missle effect with red missles 1 per point fly from the target to the caster after a hit like droplets of blood

since it will be a shape and not a blast type it cant be used/abused with eldrich glaive so only 1 per round ( auto quicken wont effect dark invocations )

idk how hard it is to do this but if anyone can its you bro

I don't play warlock much but i liked the idea =D

The Warlock already has many ways to heal himself: Fiendish Resilience, Devour Magic, UMD Wands of Cure Wounds and any healing scroll, plus the Healing Blast from Eldritch Disciple and Vampiric Feast in epic. I believe the Warlock doesn't need another healing method, that is not in PnP no less.

The energy should be spend on fun invocations like Steal Summoning or some of the epic Warlock only feats, in my opinion.
