Take the Reigns

You point your finger towards a mounted combatant within range, and perform the somatic component of this spell. When you do so the target must make a Strength saving throw. On a failure, the target is shunted from their mount with a blast of force energy and you teleport to their place at the reigns. On a successful saving throw, the target is unaffected.

If the mount has a hostile attitude towards you, then you must succeed on a DC 17 Animal Handling check to take control of the mount. Otherwise, you fall prone off of the mount at the end of your turn.
