A storm drake picks its fights carefully. Assuming it is confident of victory, it begins by using its breath weapon to separate the combatants from one another, then softens up the remaining opponents with call lightning, ice storm, and shout. If it has time to prepare, it may use control winds or control weather to create a setting more conducive to its victory. It doesn't hesitate to flee if out-matched, using either gaseous form or (if pursued) wind walk to escape.

Breath Weapon (Su): A storm drake has one type of breath weapon, a 60-foot cone of wind usable once every 1d4 rounds. This attack produces the equivalent of tornado-strength winds. Those in the cone may attempt DC 30 Fortitude saves to resist the effect.

Gaseous Form (Su): A storm drake can assume gaseous form at will as a standard action. While gaseous, the drake has a fly speed of 60 feet (perfect) and is unaffected by wind of any kind. It can't attack or use its breath weapon while gaseous, but it can use spell-like abilities normally. This ability is otherwise identical with the gaseous form spell.

Snatch (Ex): Against Medium or smaller creatures, bite for 4d6+12/round or claw for 2d8+6/round.

Spell-Like Abilities: At will - fog cloud (DC 17), 3/day - lightning (DC 18), sleet storm (DC 18), stinking cloud (DC 18), wind wall (DC 18); 1/day - control weather (DC 21), control winds (DC 20), ice storm (DC 19), shout (DC 19), wind walk(DC 22). Caster level 20th.

Air Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane Air. Air creatures always have fly speeds and usually have perfect maneuverability (see the section on Movement).
