Laughing Raven

''Harpies, manticores, angels, it doesn't matter to you. You will clip their wings and bring them to the ground, laughing all the way at your cruelty. These creatures don't deserve the gift of flight, they are weak, but although you are weaker, you are clever. Clever as you are, you are more cruel than clever. The pain of your cunning will surge through their bodies and force them to come crashing down, where you will end them. Slowly and surely.''

Wonderous Item
This is a long length of red silk ribbon that ever so often has black runic script crawl across it. Once per short rest, you may force a flying creature to make a DC 15 Con save. On a failure it takes 6d4 piercing damage and falls to the ground prone as dozens of black spines penetrate their limbs.
