SPECIAL ABILITIES

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.

Tidal Wave (Su)

A great wyrm bronze dragon can cause the sea to rise up and crush his enemies once per day as a standard action. This affects an area of coastline 120 feet in length and targets all creatures within 40 feet of the shore—treat the targets as if struck by an avalanche. Treat all creatures as if they were in the bury zone. The save DC to halve this damage is equal to the dragon’s breath weapon DC. Those who fail their saves take full damage and are drawn 60 feet off shore and deposited 20 feet under the surface on the round after the wave hits.

Vortex (Ex)

Once per day, an ancient or older bronze dragon can create a vortex as a standard action, just like an elder water elemental. A bronze dragon can maintain this vortex for 1 round per age category.

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.
