Artillery Strike is an achievement that requires the player to use a catapult in a Castle Wars game after gaining the knowledge from the Catapult Construction quest.
Just use a rock with a catapult and shoot. Players do not need to hit anyone or anything. It is strongly recommended to do this when Castle Wars is the spotlighted minigame.
- This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
