I was just reading the section about first aid and came upon this: First aid may only be applied to each Wound once and is a Full Action by you and your patient.
What does it mean exactly? For example if a PC loses 3 wounds, after counting the TB and AP bonuses, does it mean I can only heal a single wound a single time? This dosen't make much sense to me, to be honest. Maybe it means that I can only treat a single location once per day/week/month? Does it mean that I can only put a single first aid on a single wound or a specific wounded location, like an arm? But what if this arm has been damaged in two different locations, for example hand and elbow?
As far as I get it, the rules for this mean that I can only treat a single wound once, not location like hand or leg, but a wound. If my PC fails the first aid test to this wound, then he can't heal it again (at all?). If my PC does manage the test, it means that the wound is treated, even if I've only managed to heal 3 out of 4 damage points. Am I right here?
