//:://////////////////////////////////////////////
    AOE On enter:

    - Acts the same as the heartbeat, if I only used the heartbeat, it might not
      affect things it "ran over" at all!
      (note: safety catch, if they still have the Knockdown from it, or a
       special visual for same amount of seconds, the next heartbeat or any On
       Enter's won't affect them)

    - Does 3d6 damage, reflex save half, and if they fail thier first reflex save,
      there is a second else knockdown for 6 seconds.
