The latter end of Combat Over was changed just to be a bit better paced.
Namely, some enemies were removed particularly around the Fetyraks. Also on Fetyrak was changed to fire, and a Fire Fetyraks was added to add something else to use Mirror against.

Spook Up enemies were moved about a fair bit. Stage feels less repetitive.

Champion Gadron has less health in the last phases, and the hard mode last phase had the enemy rate reduced.
