Rules of the Game: Making Magic Items

[Staffan]

If you wanted to get into more complex math, the price of a partially charged wand probably ought to bottom out at the scroll price, or possibly higher - a wand is slightly more useful than a scroll in that there's no caster level/spellcasting stat issues. Then again, one can't copy a wand into a spellbook.

I'm thinking that something like 20-35% of the value of a wand ought to be in the last charge. Having the ability to launch two fireballs is a much smaller improvement over the ability to launch one fireball, than the ability to launch one fireball is over the lack of fireball-launching ability in the first place.
