Potions of Air
1st Rank: Deep Breath
Immune to air based toxins, reduce penalties from air based difficulties by 1 level per rank of Potions. Also can hold breath for extended periods of time. 'Voice' can be projected extremely loudly, or carried further on the wind than normal.
2nd Rank: Lighter than Air
Gain 2 ranks of jump and Cat's grace. If the creature already has flight, then add 1 more rank of flight, and you may remove the 'Maintain' restriction. If it did not have flight, gain 1 rank of flight, but suffer -4 penalty to CV and DV while flying.
Rank 3: Gail-force
Your breath comes out with incredible speed and strength, allowing you to blow creatures and objects away. As a combat action, make a check of Body+CV+Ranks of Potions. Any creature in 10 foot cone in front of you must make a body check against your roll, or be pushed 5 feet per point they fail by. Furthermore, all ranged attacks made by others against a target within 10ft (times your sizes above medium) suffers a penalty to the attack rolls equal to your Potions. Ranged attacks moving in the direction of your breath attack gain bonus CV equal to your ranks of Potions, and +1 range increment.
Rank 4: Strip the air
Requirement: Air Elemental Template
The drinker can control air to a degree outside of itself. This is most often used in combat to effectively suffocate the opponent, though it can also be used to 'suffocate' fires, etc. The creature gains an attack that immediately starts depriving the target of air, and in some cases actually rips the air right out of the targets lungs.
This gives 2 ranks of an attack with the 'stun, enervation (2 ranks), insidious, and toxic qualities. This does gain bonuses from any combat stats, but can't be combined with other attacks (like claws, bite, etc.) except for ones specifically designed for the same effect, like grappling, constrict attacks, etc.
