Djezet Weapon (High-Grade)

The djezet in weapons absorbs magical power. Critical hits made with a djezet weapon against a prepared or spontaneous spellcaster cause the target to lose one prepared spell or one spontaneous spell slot unless the target succeeds at a Will save (DC 30 for standard-grade or DC 40 for high-grade). The spell is randomly selected from among the caster's highest three spell levels (and then from among the spells prepared in that level, for a prepared spellcaster).
