Casting Defensively is something most people just assume a caster does. Its downright stupid for a caster to take the damage and hope to make the role. Besides, a caster is going to have pumped up his concentration check anyway. So the chance of a caster failing a concentration check is minimal or impossible. No point in not casting defensively.<br/><br/>Supernatural abilities are not subject to disruption, dispelling, nor spell resistance. Thus no need for concentration on this chicks part anyway.
