Regarding when Battle Master
s go to the KO
area when they're removed from the battlefield in upgrade mode: Do they switch to bot mode when they go there or do they stay in upgrade mode? And if they do stay in upgrade mode, how does this interact with Emergency Maintenance?
They stay on their Upgrade side and it does not interact with Emergency Maintenance because upgrades are not counted as characters.
No. When in Upgrade mode, Battle Master
s do not count as characters, so they would not be counted by Emergency Maintenance on the battlefield or in the KO area.
