I’ve liked the idea of a flying companion in Ars Magica for a long time, and only now have a write up. This effect is the classic: “grant a man wings of a bird” and as such is such a wonderful match to the imagery of the Icarus and Daedalus legend. Daedalus certainly paid for his hubris is a most vicious way, and while his crafting of waxen wings wasn’t his only great achievement in the legends (i.e. the labyrinth was a wonder too), it is one that he is most famous for.
The Cursed Gift of Daedalus
Muto Corpus 30. R: Touch, D: Sun, T: Part, Req: Animal
Grants the target a pair of wings and the ability to fly.
(Base 5, +1 Touch, +2 Sun, +1 Part, +1 Requisite)
Obviously the MuCo5 guideline requires Target: Part to be effective, and Sun is a desirable duration as Concentration is just too risky. As a story suggestion – an Athletics ability check might be used for maneuvering at the story-guide’s discretion.
