Well, I finally maxed out my two main characters on every category (guess the
Double the CP fragment skill is kinda pointless now) in
Final Fantasy XIII-2.
Bought the Snow DLC, where I have to fight him in the Colloseum. It's not related to the plot in any way, shape or form, but I'll be damned if it's one heck of a fight.
You see the trick to beating Snow is one that takes considerable amount of patience. Why? Because it's clearly a middle finger to anyone who spams the same Paradigm Shifts in one combat.
Snow can't be beat like that. First, he'll Power Up, then he'll start building up his Energy Attack. If you are still using the same PS he will eventually use Energy Max and use his special attack which kills you regardless of HP, Strengh or whatever.
In order to win, never... ever assign the same Job to a character, Noel can either be Commando, Healer, Sentinel. Serah can also be Saboteur, Medic and Synergist. Always have a Monster Healer, a Sentinel and a Commando. Occasionally it's a good idea to have a character get killed by Snow, so stack up on Phoenix Downs.
Use Ravager whenever pertinent to cause him to Stagger. When he does unleash Commando on his butt.
It's not an easy battle. Even on Easy Mode he requires a lot of strategy and careful planning.
