Harvest EXP
Gives you extra experience for harvesting fully grown crops, on top of whatever farming already gives you.
How It Works
Breaking a fully grown crop adds a little XP to you directly instead of dropping an orb. On a shared farm, the XP goes to whoever harvested the crop, not whoever is standing closest. It only works in Survival or Adventure mode.
Crops that grow in stages (wheat, carrots, potatoes, nether wart, cocoa, and similar) only give XP once fully grown. Breaking them early gives nothing. Melons and pumpkins always give XP, since those blocks only exist once they've grown.
A harvest that pays XP may also play a sound and show a message like "+2 Farming XP (Wheat)". The XP goes into your normal enchanting level. There's no separate farming level or leaderboard. Farming XP also repairs Mending gear, like any other XP.
