Fortune is an enchantment applied to mining and digging tools to increase block drops.
For coal, diamond, emerald, nether quartz, and lapis lazuli, Fortune I gives a 33% chance to multiply drops by 2 (averaging 33% increase), Fortune II gives a chance to multiply drops by 2 or 3 (25% chance each, averaging 75% increase), and Fortune III gives a chance to multiply drops by 2, 3, or 4 (20% chance each, averaging 120% increase). 1 drop has a weight of 2, and each number of extra drops has a weight of 1.
For redstone, carrots, glowstone, sea lanterns, melons, nether wart, potatoes, beetroots (seeds only) and wheat (seeds only), each level increases the drop maximum by +1 (maximum 4 for glowstone, 5 for sea lanterns, and 9 for melon slices).
For tall grass, each level increases the drop maximum by +2.

High levels of Fortune unobtainable in survival will still function normally. At extremely high levels, the excessive amount of resulting items can lead to severe lag.
Silk Touch and Fortune are mutually exclusive. If commands are used to apply both Silk Touch and Fortune to an item, the Silk Touch enchantment will take precedence over the Fortune enchantment for blocks affected by both enchantments.
