RECOVER
When you take time to catch your breath and tend to what ails you, expend 1 use of supplies and regain HP equal to 4+Prosperity. You can't gain this benefit again until you take more damage.
When you tend to a debility or a problematic wound, say how. The GM will either say that it's taken care of or tell you what else is required to do so.
Characters will often need to Recover while on an expedition. This move is described in detail on Recover, in the Harm & Healing chapter.
