I figured this would be a good place to ask this, as it pertains to the Ranger's Quarry ability, which is similar to the Warlock's Curse. The Ranger paragon path Battlefield Archer is able to designate multiple enemies as their quarry at a time (4, in my case). Since a ranger can normally only have 1 enemy quarried, the Hunter's Quarry class ability on page 104 doesn't mention if you get extra damage on each target or not.
Taken from PH page 104:
Hunter's Quarry
Once per round, you deal extra damage to your quarry. If you can make multiple attacks in a round, you decide which attack to apply the extra damage to after all the attacks are rolled.
The first part of sentence #1 leads me to believe you can only hit oneof your quarries with the extra damage, but by stating "your quarry" at the end, I can see it going the other way too. The second sentence makes me lean more towards just one target taking damage. Should I rule it as most-likely-RAI, and do it once? Or what might-possibly-be-RAW and do it against "my quarry" (four different targets)?
