Once during your move, you can mount a creature that is within 5 feet of you or dismount. Doing so costs an amount of movement equal to half your speed. For example, if your [[Movement and Position|Speed]] is 30 feet, you must spend 15 feet of movement to mount a horse. Therefore, you can’t mount it if you don’t have 15 feet of movement left or if your speed is 0. If an effect moves your mount against its will while you’re on it, you must succeed on a DC 10 [[Dexterity Saving Throw]] or fall off the mount, landing [[Prone]]] in a space within 5 feet of it. If you’re knocked [[Prone]] while mounted, you must make the same saving throw. If your mount is knocked [[Prone]], you can use your [[Reaction]] to dismount it as it falls and land on your feet. Otherwise, you are dismounted and fall [[Prone]] in a space within 5 feet of it.
