In the Wizard spell list, under level 8, there is a spell listed as "Trap the Soul". However the spell can not be found in the subsequent spell descriptions.
Some people online are saying that the spell was folded into the "Imprisonment" spell; however, that spell is level 9 not 8, and is listed as a Warlock Spell, but not a Wizard spell.
Furthermore, the spell "imprisonment" doesn't trap any souls; it only imprisons the body of the target into either beneath the earth, chains, a prison on a demi-plane, by putting the person to sleep, or by shrinking the person to 1 inch and trapping their body in a gem.
Where can I find the spell description for "Trap the Soul"?
