Cloth Of Desperation Glitch:

Unlock the Cloth Of Desperation, then defeat a Colossus. As the black strings are headed towards you, use the Cloth Of Desperation by jumping and pressing Crouch/Grab. If you are using it when the strings hit you, the game will glitch. You will be surrounded by the parachute in the shape of a clam shell when you fall to the ground. Whether you save the game or not, after you wake up in the castle it will still be glitched. To exit, get on Agro, use the Cloth Of Desperation again, or climb.
