Arcane Vitality Surge

Through years of relentless training and countless brushes with death, you master both spell and body. You gain the following: 

• Power Unleashed. When you cast a spell that deals damage, you can add your spellcasting ability modifier to one damage roll of the spell.
• Vital Recovery.  When you expend a spell slot to cast a spell of 3rd level or higher that deals damage, and you add your spellcasting ability modifier to that damage, you can regain hit points equal to your spellcasting ability modifier. Once you use this benefit, you can’t use it again until you finish a Long Rest.

Special Condition: If you already benefit from adding your spellcasting ability modifier to a spell’s effect due to another feat or class feature, you do not gain the benefit of adding your spellcasting ability modifier to your spells from this feat. However, you still gain the healing ability of this feat.
