Description: You can create wands, which hold spells
Prerequisites: 5th Level Caster
You can create a wand of any 4th-level or lower spell that you know. Crafting a wand takes one day for each 1,000 gp in its base price. The base price of a wand is its caster level times the spell level times 750 gp. To craft a wand, you must spend 1/25 of this base price in XP and use up raw materials costing one-half of this base price. A newly created wand has 50 charges. Any wand that stores a spell with a costly material component or an XP cost also carries a commensurate cost. In addition to the cost derived from the base price, you must expend fifty copies of the material component or pay fifty times the XP cost.
