Noqual Weapon (Standard-Grade)

Noqual weapons are inimical to summoned creatures and spell effects that can be damaged by conventional attacks. Against such targets, a Strike with a noqual weapon gains a circumstance bonus to damage equal to twice the number of weapon damage dice. In addition, noqual weapons disrupt spellcasters' concentration, causing them to become stupefied 1 for 1 round on a critical hit.
