Also, the more wands wizard-boy is crafting, the XP cost adds up.
'Specially with higher level wands, CL x Spell Level x 750 gp, 1/25th of that is the XP cost, per wand. So, for a 1st level spell, CL 1, it's 'only' 30XP, say it's Magic Missile, you'll burn through a bunch of charges each encounter, so it'll last only a few encounters, for a 2nd level spell, CL 3 (minimum), it's 180XP, for a 3rd level spell, CL 5 (minimum), it's 450 XP, for a 4th level spell, CL 7 (minimum), it's 840XP. That's per wand. It doesn't sound like that much, but with a character that's primarily crafting wands, well, it does add up, since, honestly, how likely is it that he'll only be making one wand for each spell he wants? he's going to make at least two, so he's got spares, quite possibly more. That XP adds up, the GP adds up too.
