What a Supercharge is
- At Town Hall 18, a building that is at its maximum level can be upgraded further with charges. Today 18 buildings can: Mortar, Air Defense, Hidden Tesla, Bomb Tower, X-Bow, Inferno Tower, Scattershot, Builder's Hut, Monolith, Multi-Archer Tower, Ricochet Cannon, Multi-Gear Tower, Firespitter, Revenge Tower, Super Wizard Tower, Gold Mine, Elixir Collector, Dark Elixir Drill.
- Defenses get two charges, the Gold Mine, Elixir Collector and Dark Elixir Drill three.
- On a defense, the first charge adds damage and the second adds hitpoints; the Air Defense gets damage from both. On a resource building the first two charges each raise capacity and production, the third adds hitpoints.
- Each charge needs a free Builder (or B.O.B). The first charge costs a lot less than the last normal level: for 11 of the 18 buildings it is 3 to 24% of it, for the other 7 it is 40 to 55%. A Supercharged building gets a blue electric glow.
- When Supercell adds a new level for a building, its charges are removed. The Sparky Stones you earned (10 per charge) stay.
New level coming
The wiki marks 10 of the 18 with New Level Coming, Depletes Soon: a new level for these is on its way, and then their charges are removed. On 20 October 2026 Supercell cut the cost and time of every charge on these 10, so they are cheaper and faster than before; the Sparky Stones you earn from them stay when the charges go.
