I still don’t understand how do you make energy fighters?

All fighting Rogers are trained in the training room. The only difference is what you equip them with. Switching armor & weapons will change their power and what they do.

Warrior armor and weapons are for the Rogers you want to fight up front with hand weapons. They are the tanks and can protect your other players from damage.

Gunslinger armor and weapons are for the Rogers you want to fight in the back. They are shooters.

Engineer armor and weapons are for the Rogers you want to fight in the middle, they can be both healers & battle with energy.

Jewelry with energy damage & energy charge are for Engineers. Energy damage is how much damage they can do before critical bonuses.

Energy charge can give your energy weapon bonuses. My favorite engineer weapon is the one that resurrects your other players when they die. Can be very useful if you have warriors in front to protect them in battles.

Engineer weapons/armor/jewelry can be found in crates or creating them in the workshops at your house.
