Battle Medicine
Feat 1
Source Pathfinder Core Rulebook
Prerequisites trained in Medicine
Requirements You are holding or wearing healer's tools.
You can patch up yourself or an adjacent ally, even in combat. Attempt a Medicine check with the same DC as for Treat Wounds, and restore a corresponding amount of Hit Points; this does not remove the Wounded condition. As with Treat Wounds, you can attempt checks against higher DCs if you have the minimum proficiency rank. The target is then temporarily immune to your Battle Medicine for 1 day.
Editors note Paizo has clarified the usage of worn tools:
Worn tools should only take 1 hand to use, as you only draw the things you need from the kit and not the entire kit. This has been marked for future errata.
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.
GeneralA type of feat that any character can select, regardless of ancestry and class, as long as they meet the prerequisites. You can select a feat with this trait when your class grants a general feat.
HealingA healing effect restores a creature's body, typically by restoring Hit Points, but sometimes by removing diseases or other debilitating effects.
ManipulateYou must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
SkillA general feat with the skill trait improves your skills and their actions or gives you new actions for a skill. A feat with this trait can be selected when a class grants a skill feat or general feat. Archetype feats with the skill trait can be selected in place of a skill feat if you have that archetype's dedication feat.
