Chapter 1 - 1. I can get out of round 1 fine but the Sully in round 2 heals faster then either character can attack. Advice?
Level them up so that they are more powerful.
Switch off auto and make sure that you are only triggering Baymax when you actually need his shields (keep him attacking as much as possible) and Olaf soon before Sulley heals so you freeze him and prevent it.
