Thunderbolt (Su)

A thunderbird can fire a ray of thunder and lightning from its outspread wings as a standard action. This attack has a range of 200 feet with no range increment, and requires a ranged touch attack to hit. A creature critically hit by a thunderbolt is stunned and deafened for 1 round if it fails a DC 22 Fortitude save. The save DC is Constitution-based.

Storm Aura (Su)

A thunderbird is surrounded by a 100-foot-radius spread of severe winds that blow out from the center, dissipating swiftly at the limit of the aura’s range. In this area, ranged weapons (but not siege weapons) take a –4 penalty on attack rolls, Fly checks are made at a –4 penalty, and exposed flames are extinguished. Small creatures must make a DC 10 Strength check (if on the ground) or a DC 20 Fly check to move toward the thunderbird, while Tiny or Smaller creatures can be knocked backward (1d4 × 10 feet if they are on the ground and fail a DC 15 Strength check, or 2d6 × 10 feet if they are flying and fail a DC 25 Fly check). Creatures on the ground that are pushed back take 1d4 points of nonlethal damage per 10 feet, and flying creatures that are pushed back take 2d6 points of nonlethal damage regardless of the distance they are pushed.

In addition, once every 1d4 rounds, a bolt of lightning strikes a random creature (other than the thunderbird) within the area of its storm aura. This bolt of lightning deals 12d6 points of electricity damage (DC 22 Reflex halves). The save DC for the lightning bolt is Constitution-based, while those for resisting the wind effects are fixed.

Stormsight (Ex)

A thunderbird ignores all vision penalties and concealment from weather effects, including those created by fog cloud, obscuring mist, and similar spells.
