Drogo
"Oh, looks grim." thinks Drogo. But he figures quick offensive action is best. Focusing his mind on the realms of fire, he calls into existance a ball of yellow flame in the palm of his right hand, which he is careful to keep above the water.
OOC: This is produce flame. On his next action, he plans to throw the little fire ball at the plant creature. Hopefully, if it extends 6 feet above the water, he should be able to aim above his companions. His attack, if this will work for round 2, would be +6(1d6)+3
