How to use the Spell Tower calculator

Choose your Town Hall, then set your current and target Spell Tower levels. Use level 0 if you still need to build the tower. Leave the boosts off for the base cost and time.

Use Add to queue to save a plan with its builder and boost settings. The queue adds the plans in order and estimates when they would finish if you started now.

The Four Spell Tower Spells

Each level unlocks a defensive spell. You can switch back to a spell you unlocked earlier. The active spell has no effect on upgrade cost or time.

Tower nameUnlocked atDefensive role
Rage Spell TowerLevel 1Boosts nearby defenses and defending units.
Poison Spell TowerLevel 2Damages and slows attacking troops in its affected area.
Invisibility Spell TowerLevel 3Temporarily conceals nearby buildings and defending units.
Earthquake Spell TowerLevel 4Damages nearby ground troops when triggered.

See Supercell's Town Hall 15 release notes for the first three modes and the February 2026 update for Earthquake.

One Spell Tower or Two?

Building and maxing two towers costs 118,000,000 Gold without boosts. Allow 67 days with one builder or 33 days 12 hours with two builders working in parallel.

If both towers are already level 1, budget 100,000,000 Gold and 53 days with one builder or 26 days 12 hours with two. If your towers are at different levels, calculate each separately.

I use the same base for Clan Wars, Clan War League and Trophy Pushing, with both towers set to Rage.
