Ravenous Sorcery

Primordial forces of hunger and carnage from beyond the veil have begun to influence your sorcery. You have gained an additional metamagic option to influence your spells.

Ravenous Spell. When you cast a spell that deals damage to one or more targets, you may spend 2 sorcery points. You recover hit points equal to half of the highest total of damage you deal to any one creature using this spell.
