Domain: Healing
When you cast a spell that lets you or an ally heal using a recovery, the target also adds hit points equal to double your level to the recovery.
Invocation of Healing: This battle, you gain an additional use of the heal spell (see Class Features, left). The first heal spell you cast after using this invocation allows the target to heal using a free recovery instead of spending a recovery.
When you cast a spell that allows an ally to heal using a recovery, you can let them use one of your recoveries instead. (If you also have the Protection/Community domain, any nearby ally can expend the recovery instead of you.)
The invocation of healing gives you two additional uses of heal this battle instead of only one.
Increase the additional hit points the target heals to triple your level.
