Rage Spell Tower unlocks at level 1.
Level 0 includes construction. Two builders can upgrade two towers in parallel.

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.
Each row is the cost and time to reach that building level, before boosts.
| Level | New spell option | Gold cost | Base time |
|---|---|---|---|
| LV1 · Construction | Rage | 9,000,000 | 7d |
| LV2 | Poison | 11,000,000 | 8d |
| LV3 | Invisibility | 12,000,000 | 8d 12h |
| LV4 | Earthquake | 27,000,000 | 10d |

| Poison Spell Tower | Level 2 | Damages and slows attacking troops in its affected area. |

| Earthquake Spell Tower | Level 4 | Damages nearby ground troops when triggered. |

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.
