Did you know that the damage output of a defense building can be calculated in different ways?
In Boom Beach, the main metric for calculating damage is by “damage per second”. However, if you tap on the little fire icon over any weapon’s information screen, you’ll see additional information described as “damage per shot”.
In some cases, the damage per shot can explain what happened to your Troops. For example, the Boom Cannon can destroy a Heavy with only one or two shots due to its damage per shot (depending on the level of the Boom Cannon and the Heavy of course). The Boom Cannon doesn’t shoot every second, but it has a high damage per shot!
