Area Attack( Savage Species, p. 30)
You can wield improvised weapons to attack several spaces at once.
Power Attack (PH) , STR 19, Huge size,
You can use your great size and strength to pick up a heavy object and attack an area as a standard action. Such an attack may consist of swinging a large log or smashing a door down on opponents' heads. The area affected is a half-circle with a radius equal to your reach. You deal damage to all creatures two or more size categories smaller than you within the area. The base damage dealt depends on your size category, as given on the table below. Add 1 1/2 times your Strength bonus to this base damage to determine the total damage for the attack. Size ------- Category Damage. Huge --------- 1d8. Gargantuan - 2d6. Colossal ----- 2d8. Though it can deal significant damage, this form of attack is awkward and unbalancing. You incur a -2 penalty to your Armor Class and on Reflex saves until your next action.
