His chakra-infused shurikens cause basic atks to randomly trigger a Wind, Wood, Fire, or Earth effect, giving attacks extra effects. With all 4 elements assembled, Element Strike casts automatically. Randomly added attribute can stack up to 5x.
When casting Iron Stance, up to 2 nearby allies also receive its effect, also increasing their physical crit rate.
