'ENCHANT WEAPON'

Usage : cast ’enchant weapon’ Accumulative: No Duration : Permanent

This spell will enchant non-magical (non-modifying) weapons only. By non-modifying weapons we refer to weapons that might alter any ability such as, for example, damage. The only way to know if a weapon is suitable for enchantment is to fully identify it.

The enchantment will modify the weapon as:

Level    Hit Roll    Damage

 0..17     +1         +1
18..19     +2         +1
20..20+    +2         +2

Enchanted weapons become not useable by people of the caster’s opposite alignment.
