You need 10 fern flowers to unlock a fifth enchantment slot. Without them, you can have 4 slots at the most.
For example, if you want to enchant a sword with I10E10A10W10F10 enchants, you need 10 fern flowers + 30 of all the other elements. If you were enchanting a sword to E10A10W10F10 only, you wouldn't need fern flowers. |
