Use this calculator to determine how much energy you will use according to how much Gunboat Weaponry you use and Tanks and/or Scorchers that you will deploy in one attack. Input a number of shots for each different weaponry type (or leave it at 0 if you have not unlocked or will not use that weaponry type during the attack), add the number of Tanks and/or Scorchers that you will use if applicable, and submit the form. The results will display the cumulative energy cost for each item as well as the total amount of energy used by all of these items in the attack.
You can also use the bottom section of the form to find out how much damage your Artillery and Barrages will do.
Barrage Effectiveness: Because of the Barrage's spread-out shots, not all of its 15 rockets may hit a given target. You may also intentionally fire a Barrage off to the side to hit another building. So, you may change the Barrage effectiveness with the last input. Generally, 14 out of 15 rockets (93.33%) will hit a 3x3 or 4x4 building if you aim at the center of it, and all 15 rockets will generally hit a 5x5 or larger building if you aim at the center of it.
