Ability
Blocking Move
1 RP
Range: Self
You move in front of the target and their movement action immediately ends. Until the end of their turn, they are Challenged by you and your next Block action against them costs 0 RP. If they willingly move from you through any method (including teleports) you may make a Heavy attack against them with Sure Hit.
Your movement may ignore Line Movement restrictions for this ability.
Requirements
You made an opportunity attack against a target moving away from you. Must be mounted.
