Translucent, writhing energy and blue sparks can be seen raging within this weapon.

A shattermantle weapon damages a foe’s spell resistance. Each time the weapon strikes a foe that has spell resistance, the value of that spell resistance is reduced by 2 for 1 round. The penalties for multiple hits during the same round stack. For example, if you succeed on three attacks in the same round against the same foe, that foe’s spell resistance is reduced by 6 until the beginning of your next turn.

Prerequisites: Craft Magic Arms and Armor, assay spell resistance (SC 17).
