Healing Transformation Feat 10
Source Pathfinder Core Rulebook
You can take advantage of shapechanging magic to close wounds and patch injuries. If your next action is to cast a non-cantrip polymorph spell that targets only one creature, your polymorph spell also restores 1d6 Hit Points per spell level to that creature. This is a healing effect.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
DruidThis indicates abilities from the druid class.
MetamagicActions with the metamagic trait, usually from metamagic feats, tweak the properties of your spells. You must use a metamagic action directly before Casting the Spell you want to alter. If you use any action (including free actions and reactions) other than Cast a Spell directly after, you waste the benefits of the metamagic action. Any additional effects added by a metamagic action are part of the spell's effect, not of the metamagic action itself.
