Jeeves thanks a lot for this idea it suits the Cthulu I am making as a NPC, but I am doing it with a Vestigial Wings for 5BP as a negative quality like insecticide features, 10 BP positive for gliding wings like the wingsuit from war and 15bp for fully functional magic wings using your descriptions
EDIT: Here is my version of the wings feature, what do you guys think?
Functional set of Wings
10-15 BP
A pair of wings grows from the back at the shoulders this may be avian or chiropteran in look. Contrary to the vestigial wings, a Functional set of Wings are fully developed and functional similarly to Eastern Dragons flight methods in a form of magical levitation, this gives the player 1 magic attribute but cannot cast spells or use adept powers unless in addition to wings she takes Adept, Magician or Mystic Adept.
Gliding wings (10 BP), these function similarly to a wing suit (War164) but speed and direction of fall may be controlled, with a glide ratio ranging from 1 meter forward to 1 meter fallen up to 5 meters forward for every meter fallen. Gliding wings use the Parachuting skill (which has its own wings specialisation) and gliding at 1 or 2 meters forward requires a Reaction + Parachuting (3) test upon landing to avoid fall damage upon landing where the damage is equal to 1d6 per 5 meters fallen.
Fully functional wings (15 BP), these give the owner full use of her wings, gaining access to the flight skill (RC88) (which has its own wings specialisation), these wings can glide as above but with a Reaction + Flight (3), these wings allow vertical take-off with a Strength + Flight (5), with modifiers +1 character is running into the wind, +2 for stronger winds, +2 for strong thermal updrafts, jumping from a high ledge or gliding gives a +3, background mana count (SM118) and mana reduction also affects flight and if your magic attribute falls below 1 your wings may only be used for gliding.
A character who is interrupted (by a successful attack that does more than (body) damage) in flight must make an Reaction + Flight (3) test to avoid falling to the ground. A character attempting to carry heavy objects receives a modifier to flight tests appropriate to the weight and bulk of the object. Metahuman bodies for example, give a modifier equal to -(body).
The character’s clothing must accommodate the wings, and he will find it impossible to wear certain items. The Functional set of Wings quality is incompatible with any other wing and back modifications or qualities.
