When fitted to a mount, this magical harness sprouts wings and grants the creature a flying speed of 60 feet. Integrated into the harness is an exotic saddle, granting you advantage on any ability check made to remain mounted.
Winged harnesses come in many styles and are often designed for a specific mount or rider. The Pereghost’s warhorse, Andaraho, wears a black harness with a 30-foot wingspan.
