It's me again, the person who made 'The Giant List of Giants, Drunks, and Killers' and the 'Put up yer dukes'. This time, I'm saying to you how to make your Black Horse faster than anything. First, find a place for a pilgrimage, then put your horse inside the pillar circle. Get off, and activate the shrine, making you able to use that shrine at any church. Then quickly hop back on to your horse and press forward on the analog stick. You should bolt out of the shrine. Run forward. Your Black Horse should run at double speed, swim at double speed, and backup at double speed. If you wait, sleep, or anything, load another game, then load the horse game, the horse will still be fast. The only known method of getting rid of this is killing the horse. Also, if you collide with a large boulder on you horse, you will melt through and appear inside the rock. You can try to get out or load another game. When I find more glitches, I'll report back to you. Later.
