Brew Potion( Player's Handbook v.3.5, p. 89)
You can create potions, which carry spells within themselves. See the Dungeon Master's Guide for rules on potions.
Caster level 3rd,
You can create a potion of any 3rd-level or lower spell that you know and that targets one or more creatures. Brewing a potion takes one day. When you create a potion, you set the caster level, which 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 x its caster level x 50 gp. To brew a potion, you must spend 1/25 of this base price in XP and use up raw materials costing one half this base price. When you create a potion, you make any choices that you would normally make 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.
