You can easily divide your attention between chosen targets.

Encounter   ✦     Martial
Minor Action      Ranged sight

Target: One creature

Effect: You designate the target as your quarry, even if it isn't the closest enemy to you. The target doesn't count against your normal limit of one quarry at a time, although you can still deal your Hunter's Quarry damage only once per round.

Special: Using this power doesn't provoke opportunity attacks.
