This magic item is best attached to a dragon champion, to ensure that its special power can be used. Combat is ended, and both champions return to their pools. The entire combat is over; the attacker cannot continue with a new champion. The Bones do not have to be in the battle to be used. Since the power affects both champions in battle, if only one is immune, then the battle must continue. This is because champions cannot voluntarily be affected by something to which they are normally immune. If only one champion were effected, the power would be incorrect ("combat ends without a victor"), thus it is simply not effective.
