Your ability to channel divine magic is near unmatched in this realm. You are able to channel a restorative aura around you for 30 feet.
Spend an action and one 8th level spell slot to activate this feat. Once activated, you can channel this aura and every turn thereafter you can cast Greater Restoration and Mass Cure Wounds on up to 8 creatures in your aura.
To channel such strong magics is incredibly deadly even for someone of your skill. Every time a creature is affected by the aura (using either Greater Restoration or through Mass Cure Wounds) you expend 3 hit die and take 3d6 of damage this represents you channeling your life force into maintaining this effect. If all your hit die are used, you die and are unable to be resurrected by anything short of a Wish Spell.
