While an attraction spell is good for a fling or a crush, it’s not so much for long-lasting love. Binding spells are performed to put the subject under the power of the person casting the spell.

The Scroll of Planar Binding is a Spell Scroll found in Baldur's Gate 3. It allows you a free cast of the Planar Binding spell. Scrolls can be scribed by a Wizard to learn the spell permanently.
