This particularly applies to the new Razor Hydra from MM2. They have an ability that gives them a +2 to attack rolls against targets suffering from ongoing damage. There bite provides ongoing damage.
So my question is lets say they begin a hydra fury attack, and on the first attack hit. Do they get a +2 on the 3 other attacks against the target, or would all attacks happen at the same time, and all would get no bonus?
