|Storm Aura|Stormsight|Thunderbolt
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 suffer a -4 penalty on attack rolls and exposed flames are extinguished. Creatures must make a Paralysis save to move toward the thunderbird.

This bolt of lightning deals 2d8 electricity damage (Breath save halves).
