Division

(This spell counts as an Ethelleturgy Spell)

You divide the assemblage of a willing Humanoid you touch into its three distinct segments, allowing the soul, body and mind to each act on their own for the duration. While affected by the spell, the creature's current Hitpoints are divided by 3 (rounded down), as two metaphysical duplicates of them appear within 5ft. Each duplicate appears with the same Hitpoints and AC as the affected creature. 

On the affected creature's turn, each Duplicate may move up to half of the affected creature's movement speed. Whenever the creature makes an attack on their turn, they may have each duplicate make the same attack towards a creature within range. Whenever the creature casts a spell on their turn, they may have each duplicate cast a spell of the same level and casting time. (Consuming additional spell slots as normal)

If any Duplicate is reduced to 0 Hitpoints, the spell immediately ends, and all the Duplicates vanish. Whenever the spell ends, the affected creature regains all Hitpoints left between the Duplicates as they vanish.
