The Stone Slammer is a heavy-duty, flying mountain that tragets defensive building by flattening them with gaint boulders and causes earthquakes. Immune to spell effects.
- The Stone Slammer is the third Siege Machine you unlock, available when the Workshop is upgraded to level 3.
- Stone Slammer prioritize defensive structures above all other targets, and will bypass all other types of enemy buildings and troops while any defenses remain on the battlefield. This is true even if they are under attack by enemy Clan Castle troops, heroes or Skeleton Trap skeletons. Note that like all troops that prioritize defenses, Stone Slammer do not consider the Clan Castle to be a defense regardless of whether or not it contains enemy troops, but do consider the defending Grand Warden and the level 12 Town Hall (if its Giga Tesla has been triggered) to be defensive buildings. Once all defenses are destroyed, Stone Slammer become like any other troop with no preferred target; they will attack the nearest building to them regardless of type, and will turn and attack enemy units if they become aware of any nearby.
- The Stone Slammer does not prioritise Walls, but it can deal up to 25x damage against them. This damage multiplier decreases with distance from the target, however.
- The Stone Slammer can still be used if there are no Clan Castle troops, however, when it is destroyed, nothing will spawn from it.
