Stone Slammer
Siege MachineUnlocks at TH126 levels
The Stone Slammer is a heavy-duty, flying mountain that targets defensive buildings by flattening them with giant boulders and causes earthquakes. Immune to spell effects.
How it works
- •A flying, defense-targeting siege - like a supercharged Balloon with a wider splash radius.
- •Each boulder has two hitboxes: a 1-tile high-damage hit plus a 3-tile splash that deals 25x damage to Walls.
- •Deals damage when destroyed and drops your Clan Castle troops where it falls.
