Secret Art: Chase the Horizon

You focus on a single enemy and maintain a constant position from them. Whenever the target moves, you may move the same amount as they did (up to your movement speed) away from them for 0 RP. This movement does not provoke attacks of opportunity from the target, but does provoke from other enemies.

 Every time this happens, you may make a Light attack against the target with a ranged weapon. If the target spends multiple AP on a single movement action, you may make an amount of Light attacks equal to the AP they spent.

Lasts until the start of your next turn or until you can no longer see the target.
