The Lightning Long sword can be chaos and Gargoyles are weaker to fire damage thank lightning (very slightly weaker though). The Knight shield and armor is but a trick of the eye against scrub lords who invade new players with 400+ damaging weapons. Power Within would allow you to deal massive damage to the Gargoyles, needing 6 hits (for both Gargoyles) or less. Or you could throw some fireballs at the Gargoyles (with power within of course) and kill both without using anything else. PRAISE THE SUN!
