Once every 1d2 rounds, a thunder gigas can cause the ground to erupt around it within a 30-ft.-radius. Creatures within the area of effect take 8d6 points of earth damage and are inflicted with the Weighted status effect for 1d6 rounds. A successful Reflex save (DC 24) reduces the damage by half and negates the status effect. Blue mages may learn this ability as a 4th level spell (Knowledge: Local DC 23).
Lightning Roar (Su)
3/day, a thunder gigas roars an electrifying cone blast within 45-ft. burst. Any creature within the area of effect takes 15d6 points of lightning damage and are inflicted with the Static status effect for 1d6 rounds. A successful Reflex save (DC 24) reduces the damage by half and negates the status effect. Blue mages may learn this ability as a 6th level spell (Knowledge: Local DC 27).
