Titan's Fury

You grow thrice your size. You gain 100 temporary hit points, but once your 100 temp hp is gone you shrink back to normal size. You do double damage on melee weapon attacks and unarmed strike attacks, but attacks done to you do double damage as well. Your AC is reduced by 2 because you're a bigger target, but your speed is increased by 30ft. Once you use this you can't use this feature again until the next dawn.
