Breath Weapon (Su): Either a line of lightning 5 feet high, 5 feet wide, and 5x5x80 feet long or a cone of repulsion gas 40x40x40 feet long. It cannot use either breath weapon until 1d4 rounds later. Lightning damage 8d6, Reflex half DC 20; gas damage Will save (DC 20) or be compelled to do nothing but move away from the dragon for 1d6+4 rounds. This is a mind-influencing compulsion enchantment.

Spells: Knows and casts arcane spells as a sorcerer of level 3, gaining bonus spells for a high Charisma score. Can also cast cleric spells and those from the Animal, Law, and Water domains as arcane spells.

Spell-Like Abilities: At will - speak with animals; 3/day-polymorph self. A bronze dragon's polymorph self ability works just like the spell, except that each use allows only one change, which lasts until the dragon assumes another form or reverts to its own (which does not count as a use of this ability). These abilities are as the spells cast by a 4 level sorcerer (save DC 14 + spell level).

Immunities (Ex): All dragons are immune to sleep and paralysis effects. All bronze dragons are also immune to electricity.

Water Breathing (Ex): A bronze dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged.

Blindsight (Ex): Can ascertain creatures by nonvisual means (mostly hearing and scent, but also by noticing vibration and other environmental clues) with a range of 120 feet.

Keen Senses (Ex): Sees four times as well a human in low-light conditions and twice as well in normal light. It also has darkvision with a range of 400 feet.
