Strategy 1 (ft. Octopus Cat)
To win before the Heavy Assault C.A.T. appears, just deploy Awakened Bahamut Cat ASAP and make sure it is protected by enough meatshields as well as Octopus Cat. No item is needed. The Berserkory can ￼appear for 2 seconds when you are hitting the base, but since you have Octopus Cat it is not an issue at all.
