Beast Intercept

You can command your beast companion to cut off a moving creature.

Prerequisite : Ranger level 9, Beast Master Archetype.

Benefit: You can use your reaction to command your beast companion to move up to its speed to a square adjacent to an enemy. If your beast companion ends its movement adjacent to that enemy, it can make one melee attack. If the attack hits, the speed of the enemy becomes 0 until the end of its turn.

Once you use this feature, you cannot use it again until you finish a long rest.
