# Cannon

The Cannon is a structure that is automatically built after a Power Plant is built and gives a Guild the ability to attack other Guilds.

Attacking other Guilds consumes Attack Charge, which must be recharged. The Attack Charge scale is charged through an Energy donation available to any Guild member, similar to building or improving structures.

Each subsequent level of the Cannon increases the number of shots fired, increases the Energy cost of a shot, increases the maximum size of the Attack Charge scale, and increases the number of resources that can be looted in a single turn.
