Fly Free (5e Feat)
From D&D Wiki
Prerequisites: must have wings and a flying speed.
Use your wings as they were intended and fly without restrictions.
- You gain a permanent 30ft flying speed.
- If movement is restricted by your armour you can fly if you have your armour modified (medium armour 5gp, heavy armour 10gp to have it modified so your wings are free to move).
