While playing is FSC today, someone had an Electron Vortex(I don't know what star count it had.) and I had a War Hammer. He would lay the bomb, then I could use the charge of the hammer on the enemies caught in the vortex. It is a very powerful technique because the hammer charge will deal almost 1k damage, but it can be hard to hit with because it will knock enemies away. The vortex keeps this from happening, and if you bomber uses bomber gear, he can chain the bombs together, and the hammer-er can chain the charge infinity.
Simply put, discuss and share techniques like this one. It doesn't need to have 2 people. It could just need one person, or 4 people. Same goes for weapons: you don't need to use 2. You could use 1 to 16. (Although, a combo involving 16 weapons would get very complicated indeed!)
