What blocks does the fortune enchant work on?

Solution 1:

Any block which drops an item other than the block itself when mined.

This includes:

  • Coal
  • Diamond
  • Redstone
  • Emerald
  • Lapis Lazuli
  • Nether Quartz
  • Melon (capped at 9 melons)
  • Clay (Capped at 4, but increases the chance of getting 4)
  • Seeds (from tall grass and wheat, but doesn't increase the actual wheat drop itself)
  • Nether Wart
  • Glowstone (capped at 4 dust, but increases the chance of getting 4)
  • Increases the chance of gravel dropping flint
  • Increase of dropping saplings and apples from leaves

Fortune works differently for different things. Most notably, at Fortune III you have a 20% chance to get twice as many drops, a 20% chance to get 3 times as many drops and a 20% chance to get 4 times as many drops for Coal, Diamond and Lapis Lazuli.

All others work similarly to Looting on a sword, increasing the maximum limit and therefore increasing the chance that it drops a lot of things, but not explicitly doubling or tripling the dropped amount.
