Mounted Combat

A willing creature that is at least one size larger than a rider and that has an appropriate anatomy can serve as a mount, using the following rules.

Mounting and Dismounting

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 (round down). For example, if your Speed is 30 feet, you spend 15 feet of movement to mount a horse.

Controlling a Mount

You can control a mount only if it has been trained to accept a rider. Domesticated horses, mules, and similar creatures have such training.

The Initiative of a controlled mount changes to match yours when you mount it. It moves on your turn as you direct it, and it has only three action options during that turn: Dash, Disengage, and Dodge. A controlled mount can move and act even on the turn that you mount it.

In contrast, an independent mount--one that lets you ride but ignores your control--retains its place in the Initiative order and moves and acts as it likes.

Falling Off

If an effect is about to move your mount against its will while you're on it, you must succeed on a DC 10 Dexterity saving throw or fall off, landing with the Prone Condition in an unoccupied space within 5 feet of the mount.

While mounted, you must make the same save if you're knocked Prone or the mount is.
