wwn/game-rule/combat-action# Combat Action: Use a Skill
The combatant uses a skill that could be plausibly applied in a few seconds. An Int/Heal or Dex/Heal skill check to stabilize a wounded comrade is one such potential use, as is turning a creaking engine wheel, shouting out a stirring rallying cry to timorous NPC allies, or anything else that might be done quickly.
