When drinking this potion the drinker regains 2d4+2 hp immediately. Then, the drinker comes under the effect of the Charm Person spell for one hour. The “Caster” of the Charm Person spell is the individual who originally brewed the potion.
If a character is proficient with the Herbalism Kit, and has access to a kitchen, a cauldron or similar, they may attempt to take over the ownership of the spell. In order to successfully do this, the character must make an Arcana check, and beat a DC equal to the Spell save DC of the original creator of the potion.
