Once every 1d2 rounds, a fire 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 19) 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).
Fire Roar (Su)
3/day, a fire gigas roars a fiery cone blast within 30-ft. burst. Any creature within the area of effect takes 10d6 points of fire damage and are inflicted with the Burn status effect for 1d6 rounds. A successful Reflex save (DC 20) reduces the damage by half and negates the status effect. Blue mages may learn this ability as a 5th level spell (Knowledge: Local DC 25).
Heated Rock (Su)
Fire gigas transfer the heat of their bodies to rocks as part of an attack action when they throw rocks. A heated rock deals 1d6 points of additional fire damage on a hit.
