A1: That was just my poorly worded way of saying that Sun-Sundi was in the path of the lightning bolt.
A2: Yes, the minimum is 15 with Spell Penetration, which I failed to apply. Jabba's CL check result should have been a 15. I apologize for my error.
A3: A draw? I should have noticed that. Let me check. If neither combatant damages the other by the end of round 524, there will be a draw. However, if Sun-Sundi does not exit the Victory Zone between now and then, Sun-Sundi will be able to choose to negate the draw by virtue of having been in the VZ for three consecutive rounds.
