If I want to buy a wand with a caster level higher than minimum, how do I calculate the cost? The prices given in the Corebook are for minimum caster level. Say I want a wand of Fireball with a caster level 10th. Thanks.
The market price of a wand is spell level x caster level x 750 gp. So a wand of fireball (10th) would cost 3 x 10 x 750 = 22,500 gp.
Use the wand formula. I think it's spell level times caster level times 750. So you are looking at 30*750.
