Artillery

"Your Gunboat fires a high-explosive cannon shell that damages enemy buildings. Be careful not to hit your own troops!"

Summary

• Artillery is the first Gunboat weapon available, unlocked at Headquarters level 1.
• Artillery fires a single projectile at the target point, damaging all Troops/Buildings and setting off all Mines, Boom Mines, and Shock Mines on hit.
• Each shot costs 2 more Gunboat Energy than the previous, with a starting cost of 3 Gunboat Energy.

Offensive Strategy

• Use Artillery to destroy key Defensive Buildings so that your troops do not come under fire from them.
• Artillery can trigger mines, neutralizing them before they threaten your troops. However, the Barrage is more effective for widely dispersed mines due to its large area of effect.
• Artillery shells deal splash damage. As demonstrated in the image below, up to four buildings can be damaged with the same artillery shell.

• It is possible to destroy resource and supportive buildings to accumulate more energy for other Gunboat Weaponry, but it is wise to ensure you receive more than spend on firing Artillery. Even then, Critters are more effective versus non-defensive buildings.
• Artillery can be used to "mark" targets for smokey Zooka attacks on defenses in Operations. Provided that no other targets in range are more severely damaged than the marked target, the Zookas will act to attack the marked target(s) first if a Flare is not used. A similar strategy can be used to target particular buildings when using the Universal Remote.

Defensive Strategy

• Do not place buildings adjacent to each other, not even adjacent at a corner, as they can all be damaged or destroyed at the same time. 
• Upgrade defenses that are common Artillery targets to increase their health. If a defense has a lot of health, an attacker will have to use more energy to destroy it. Building Health Statues can also be used for this reason.

Upgrade Differences

• There are no visual differences between upgrades. However, damage increases (by 8-11%) with each level.

Trivia

• The Artillery is featured as a character skin for the King's Tower in Clash Royale.
• Artillery's icon and projectile began as a simple, large cylindrical shell topped by a red dome, structured similarly to many others in the 20th century and beyond. It was eventually replaced with the current one at an unspecified date.
