Jedi or Sith

You concentrated harder this time. But it is still not working. Suddenly you felt tired, weak. You also saw a light between your hands! You accidentally learned Force Body, draining your own health to give your powers a boost.

Zac was surprised that you were able to get Force Blast under control, but he was not intimidated. Finally you released your power. Zac did the same. Both of your powers are now in a Force lock. Either one of you can win. Surprisingly both of have to same level of power. You could use Force Body again to gain the advantage, but then you might die.
