This attack can cause nasty, lasting burns to any target that takes damage. Unless the target takes a basic action to put out the burns, it will take one additional hit at the end of the round and the effect ends. A friend can help stop the burn before it inflicts damage, but this requires a First Aid stunt with a difficulty equal to the damage rating of the attack that caused Burn. A creature can only have one burn effect active at a time, even if damaged by several different types of attacks that each cause burn.
