Atreiti's Planeswalker Binding

A bright light, that offers no real illumination somehow, takes shape in the cloud of heat and smoke produced from the burnt offering. The soul of a CR 1 or lower non-humanoid it belonged to is pulled to this plane. After half a minute, the bright light takes shape as the actual soul of the being, and it must make a wisdom check against the caster's spell DC. If unsuccessful, the being will not be under the caster's control when summoned. During the last half-minute, the body of the being takes shape, completing after the full casting time has passed. The summoned being is not a representation, but the actual being. When it dies, it is not unsummoned, and the spell will no longer work for that being.

If the caster maintains concentration for a full day, the summoned remains on the plane permanently. Once concentration is lost, if the summoned was unwilling, it is hostile to the caster until the end of the 24 hours, after which it is pulled back into its own plane.

• At higher levels: When you cast this spell using a spell slot of 2nd level or higher, you may summon a being with a CR matching the spell slot level or lower. If done at level 3 or higher, Planeswalker Binding may summon a willing humanoid.
