While building a character for the newest season of encounters (Blackguard) I decided to take the Sentinel Marshal Theme. As part of the entry package for the theme you receive the Marshall's interdiction encounter power. In that power it states that:
Effect: The target is immobilized until the end of your next turn. You also mark the target until you end your turn without hitting or missing it with an attack. In addition, you designate the enemy as your marshal’s quarry until the end of the encounter. -via Compendium (Dragon # 407)
However, Marshal's Quarry isn't listed anywhere in the compendium or described in the original Dragon article beyond reference the Marshal's interdiction power referencing it. I assume it works similarly to the Hunter's Quarry power of the Ranger class, but if anyone had any sort of errata, faqs, or just anything from the designers/publishers clarifying it I would appreciate it.
