You need 15 bookshelves placed around an enchantment table to reach the maximum enchantment level of 30 in Minecraft. While you can place up to 24 bookshelves, adding more than 15 does not increase the enchantment level beyond 30. The bookshelves should be placed with a one-block gap around the table, typically forming a 5x5 square with the enchantment table in the center. In summary:
- Minimum for max enchantment level 30: 15 bookshelves
- Maximum bookshelves that can be placed: 24 (no extra benefit beyond 15)
- The bookshelves must be placed one block away horizontally and can be stacked up to two blocks high
This setup will allow you to access the highest level enchantments for your tools, weapons, or armor at the table.
