+Aid+

To give first aid, pick an ally within the activating fighter’s reach. Make a Sagacity check, getting -1 for each injury that ally has taken so far this battle. If passed, you can either remove an injury and D5 damage. If failed, nothing happens. However, if you fail by double or more you inflict another injury to the ally you were trying to aid.

For example, Skald has a Sagacity value of 6 and an ally within his reach that has rolled twice on the injury table. On the Sagacity check if he rolls a 1-4 he can remove an injury from his ally, on a a 5-7 he fails to help his ally, and on a 8-10 he hurts his ally instead having him roll on the injury table for a third time.
