A Book of Building sells for 50 Gems in Clash of Clans.
Magic Items are valuable consumable items in Clash of Clans that significantly accelerate progress by instantly completing various tasks, such as upgrades, research, or troop training. While their primary value lies in their utility, players also have the option to sell these items for a small amount of Gems. This can be particularly useful if a player reaches the maximum capacity for a specific item and needs to make space, or if they simply prefer to convert an unneeded item into a different resource.
Understanding Magic Item Sales in Clash of Clans
When you obtain a Book of Building, or any other Book-type Magic Item, and you don't have an immediate use for it or have already reached your storage limit of one, the game provides an option to convert it into Gems.
- Standard Selling Price: The selling price for a Book of Building is consistent with other "Book" type Magic Items. All Books, including the Book of Spells, Book of Heroes, and Book of Everything, sell for 50 Gems each.
- Capacity Considerations: Most Books have a maximum capacity of one, meaning you can only hold a single instance of that specific Book at any given time. If you receive another Book when your inventory is full, you will typically be prompted to sell the one you currently possess to claim the new one, or the incoming item might be lost depending on its source.
- Strategic Choice: While selling a Magic Item provides a quick influx of Gems, their primary benefit often far outweighs the modest selling price. Using a Book to instantly complete a lengthy upgrade can save days or even weeks of build time and millions of resources, which is generally more beneficial than the 50 Gems received from selling it. However, if you are actively saving for a significant Gem purchase, such as an additional Builder Hut, selling an unneeded Book can contribute to your Gem total.
Below is a summary of the selling prices for various Magic Items:
| Name | Max Capacity | Selling Price (Gems) |
|---|---|---|
| Book of Building | 1 | 50 |
| Book of Spells | 1 | 50 |
| Book of Heroes | 1 | 50 |
| Book of Everything | 1 | 50 |
