Elemental Attack 
Choose from air, earth, fire, metal, water, or wood (this choice can't be changed once you select it for the impersonator). The noppera-bo impersonator targets a creature within 60 feet and creates a detonation of that element; that creature takes 4d6 @item.flags.system.rulesSelections.elementalAttack.damage (slashing (air), bludgeoning (earth, water, or wood), piercing (metal), or fire (fire)) damage (DC 24 reflex save). Elemental Attack gains the appropriate elemental trait.
