Since we haven't seen any visuals of the new spell I thought the new spell should mimic the art that inspired it.
Storm, Earth and Fire: Cosmetic idea
Storm: While the spell is active the monk crackles with White Lightning. (Character has a White Glow)
Earth: The First Clone Swings a Giant Stone Panda Totem. (Clone has a Green Glow)
Fire: The Second Clone of yourself cast dual-weilds to burning Katanas like in the picture. (Character has a Red Glow)
