Brew Potion
[Item Creation]
You can create potions which carry spells within themselves. See DMG for rules on potions.
Prerequisite: Spellcaster level 3rd+
Benefit: You can create a potion of any spell of 3rd level or lower that you know and that targets a creature or creatures. Brewing a potion takes 1 day. When you create a potion, you set the caster level. The caster level must be sufficient to cast the spell in question and no higher than your own level. The base price of a potion is its spell level multiplied by its caster level multiplied by 50 gp. To brew a potion, you must spend 1/25 of this base price in XP and use up raw materials costing half this base price.
When you create a potion you make any choices that you would normally take when casting the spell. Whoever drinks the potion is the target of the spell. Any potion that stores a spell with a costly material component or an XP cost also carries a commensurate cost. In addition to the costs derived from the base price, you must expend the material component or pay the XP when creating the potion.
