Let's share tactics

[Choco]

No wizard worth his Int score has one book. There's an adventuring book plus a book in his stronghold, and possibly one in the mage guild vault. Probably also tattoos of the most crucial spells on his body (teleport, orbs, enervation, dominate, glitterdust). He teleports somewhere, prepares spells (even if only those tattood on himself), and comes back with a full load.

Exactly, which is why in my first post I specified that if they even let you get into melee range to begin with, they likely do not know what they are doing (unless it is all part of the plan of course...).

Plus, there's also sunder's constant problem that you just sundered most of the treasure you were going to get for killing the wizard.

Still better than having the wizard kill you.
