Keep Pace

Trigger Your prey is within reach and attempts to move away from you.

Bounty Hunter Once you are upon your prey, they can't escape.

Game Hunter When your hunted prey tries to bolt, you follow.

Stride up to your Speed, following the foe and keeping it in reach throughout its movement until it stops moving or you've moved your full Speed. You can use Keep Pace to Burrow, Climb, Fly, or Swim instead of Stride if you have the corresponding movement type.
