Battle Healer

When you are in melee of an enemy and use Healing Word or Mass Healing Word to heal any of your ally, you regain hit points equal to your strength or dexterity modifier + half your spellcasting modifier rounded down. For the purpose of buffs the rest of your equipment might give you, the hit points you regain are not considered as being healed.

You gain proficiency in medicine. If you already have proficiency, your proficiency modifier is doubled.
