False love's kiss is a more powerful version of charm person. Preparing false love's kiss involves casting the spell over a mixture of striped toadstool poison (see the Dungeon Master's Guide, pages 296-297) and a half-pint of wine. This creates a clear, wax-like substance that is applied to the caster's lips. The caster must then kiss the subject of the spell, who gets a Will save to avoid the effects. If the save is failed, the target sees the caster as a friend, much like the charm person spell.
The duration of false love's kiss may be extended by one day if the caster makes a successful Diplomacy check opposed by the target's Sense Motive skill. This check must be made before the spell's duration ends, and the caster and the target must be together for at least one hour before the check can be made. Only one such check can be made per day.
The waxy gloss created by this spell remains potent for up to one day or until the spell is discharged.
Arcane material component: The striped toad poison and a half-pint of wine.
