Creating these since it has been requested by multiple people. These videos will have to be broken in 2 parts since it is not possible to complete all missions in 1 clear. These are very late, but I still hope they prove useful to those who have not yet cleared them.
The strategy for this quest was to kite Mont around the map while killing the other 4 enemies and then use slow and agility down on Mont to create a chain and finish him off. The second set of enemies are much easier to deal with and can for the most part be killed before they have a chance to act. Mainly because by this point, an esper evocation will have been used to boost your party's damage. Macherie proved to be the most difficult to deal with because of her healing and tankiness along with her calamity guard.
The light team clear was especially difficult because of the low damage from Camillo, Fina, and Phoebe. Only Ellshra had decent damage output, but her range is not very good. A lot of optimizations were made in order to make incoming damage manageable. There are no healing restriction missions so Fina is able to heal freely if needed.
