Wizard's Familiar, a leveling dagger for wizards only

This is a set of scripts and items that basically makes a dagger 'level up' when wielded by a wizard. The blade doesn't do much for non-wizards, but gets very powerful as the wizard gains levels (granting feats, extra spell slots, extra damage, gaining spellcasting powers...). It reverts to the base item when unequipped. The dagger does not level up while wielded - it does it at the time it is equipped. The base dagger can be wielded by anybody, it just doesn't level up for non-wizards. The erf includes the base dagger (two versions, one normal and one already identified), 9 leveled up versions of the dagger (1st, 5th, 10th, 15th, 20th, 25th, 30th, 35th, and 40th), and all the scripts I used.

This item and scripts was created as an experiment that actually worked. It could probably be done with different scripting and variables and such, but this method seemed to be the simplest to understand (I'm a beginning scripter) and implement.

[Edit:] I've reworked this item so that it makes use of tag based item scripting. A new .erf has been uploaded (as of May 3rd, 2005) to the Vault that does not contain the old equip_scriptrun and uequip_scriptrun scripts.
