Unmodified 「空中バランス」 represents the ability to twist in midair in order to land softly. This might be inborn or the result of secret acrobatic techniques.
With suitable modifiers, it can represent other fall-breaking measures, from parachutes or retrorockets to super-powered gravity control.

■New Special Enhancement
Feather Fall: You always enjoy the benefits of 「空中バランス」, even if bound and dropped on your head. +20%.

■New Special Limitation
Parachute: You have a natural parachute, such as wings or skin flaps.
This works like unmodified 「空中バランス」 for falls that take two seconds or more, but deploys too slowly to affect shorter falls (distances of 6 × g yards or less). Your parachute needs open air in a radius equal to your height to function; it’s worthless if falling down a narrow passage, and is of no use in “very thin” or thinner atmospheres. -30%.

■Powering Up
Any power that can lower gravity or density, or justify 「飛行」, might include 「空中バランス」. For Gravity, 「サイコキネシス」, etc., add the Feather Fall enhancement. Those who have chi powers can use unmodified 「空中バランス」 to simulate “body lightening” (karumijutsu).
才能 adds to DX rolls to halve damage in all cases.
