Electricity Aura (Su)

An old or older bronze dragon has an aura of electricity. All creatures within 5 feet take 1d6 points of electricity damage at the start of the dragon's turn. An ancient dragon's aura is 10 feet. A great wyrm's damage increases to 2d6. A bronze dragon can suppress this aura at will.

Repulsion Breath (Su)

Instead of a line of electricity, a bronze dragon can breathe a cone of repulsion gas. Targets must make a Will save or be compelled to do nothing but move away from the dragon for 1d6 rounds plus 1 round per age category. This is a mind-affecting compulsion effect.

Water Breathing (Ex)

A bronze dragon breathes water and can use its breath weapon, spells, and abilities underwater.

Wave Mastery (Su)

For up to 10 minutes per age category per day, a juvenile bronze dragon, along with creatures or vessels within 50 feet, can move at twice its normal speed in water.
