Sorry, I missed this earlier. To my surprise, the rules don't say on a fire giant. For a stone giant, it says "It uses both hands when throwing a rock." Since stone giants are supposed to be the best at rock throwing/catching, I'd say all of them require two hands.Gansk said:I'm not sure if giants need one hand or two to throw rocks, so the disposition of Flambe's greatsword may or may not be a factor in the following round (rules help welcome).
