Reptilian Wings

You sprout wings/put on bio mechanical Reptilian wings (if your not an reptilian species). With your wings, you have a flying speed of 20 feet if you aren’t wearing heavy armor and aren’t exceeding your carrying capacity. Note: the wings can not be removed after being put on it'll fuse with your being (bio mechanical ones do need a fuel of three coal peices per in game week) (you now can use coal as a food source, your teeth are as hard as a iron pickaxe)
