Herbalism

Herbalism is mcMMO's farming and foraging skill. You train it by harvesting plants: crops, flowers, mushrooms, cacti, sugar cane, vines, coral, nether growth and more. As you level you get bonus drops when harvesting (Double Drops, then Verdant Bounty for triple), your hoe can auto-replant crops (Green Thumb), you dig up rare items from foliage (Hylian Luck), you spread mushrooms (Shroom Thumb), and you unlock Green Terra, the super ability that tripples drops and supercharges Green Thumb.

Earning XP

Every harvestable plant has its own flat XP value from experience.yml. A few highlights:

Double Drops

Double Drops is the bread-and-butter perk: a chance for every harvested plant to drop twice as much. The chance scales linearly with your Herbalism level:

Herbalism:
    DoubleDrops:
        ChanceMax: 100.0
        MaxBonusLevel:
            Standard: 100
            RetroMode: 1000

So a level 50 standard player doubles roughly half their harvests; at level 100 every eligible plant double-drops.

Verdant Bounty: triple drops

Verdant Bounty is the high-level upgrade to Double Drops: when a drop is rolled, Verdant Bounty can turn it into a triple drop instead. It unlocks very late and tops out at a 50% chance:

Herbalism:
    VerdantBounty:
        ChanceMax: 50.0
        MaxBonusLevel:
            Standard: 1000
            RetroMode: 10000

While Green Terra is active, every bonus-drop roll is automatically a triple drop; Verdant Bounty's RNG is skipped.

Green Thumb: auto-replant & mossy blocks

Green Thumb has two jobs.

1. Auto-replanting crops. When you harvest a mature crop with a hoe (and you're not sneaking) and you have the matching seed in your inventory, Green Thumb has a chance to instantly replant it. It works on wheat, carrots, potatoes, beetroots, nether wart, cocoa, torchflower and sweet berry bush. The chance scales with level:

Green Thumb also has ranks (unlocked at levels 25 / 50 / 75 / 100 in Standard) that control how grown the replanted crop comes back: higher ranks replant crops at a later growth stage, so they finish sooner.

2. Making blocks mossy / grassy. Holding wheat seeds and right-clicking certain blocks spreads green growth onto them: cobblestone → mossy cobblestone, dirt → grass, stone bricks → mossy stone bricks, and so on. This is gated by its own permission nodes (see below).

Hylian Luck

Hylian Luck gives a small chance, when you break certain foliage (tall grass, ferns, flowers, etc.), to find a rare item instead, themed after smashing bushes in Zelda. It caps at a 10% chance:

Hylian Luck unlocks at level 1. The specific treasures and their per-item drop chances come from the Hylian treasure table in treasures.yml.

Shroom Thumb

Shroom Thumb lets you spread mycelium onto dirt and grass. Hold a mushroom and consume one brown and one red mushroom to attempt it; on success the block becomes mycelium. The chance caps at 50%:

If the roll fails, the two mushrooms are still consumed.

Farmer's Diet

Farmer's Diet makes farmed food (bread, carrots, melon, etc.) restore more hunger when eaten. It improves in 5 ranks:

Green Terra: the super ability

Green Terra is Herbalism's super ability. While it's active:

• Every eligible harvest gives a triple drop (no RNG, Verdant Bounty's roll is bypassed).
• Green Thumb is guaranteed and effectively boosted by one rank, so crops replant at a more advanced growth stage.
• You can right-click blocks with seeds to spread green growth (the same mossy/grass conversion as Green Thumb, but spent directly through the ability).

How to activate it

1. Hold a hoe.
2. Right-click the air to ready your hoe ("You ready your Hoe.").
3. Left-click a block within the activation window to trigger Green Terra.

Green Terra unlocks at Herbalism level 5 (Standard) / 50 (RetroMode).

Duration

duration (seconds) = 2 + min(cap, Herbalism level) ÷ IncreaseLevel

A level 50 standard player gets 2 + 50/5 = 12 seconds; a level 100+ player gets the full 22.

Cooldown

Green Terra has a 240-second cooldown by default (Abilities.Cooldowns.Green_Terra). There is no maximum-length cap by default (Max_Seconds.Green_Terra: 0).

Commands & permissions

Green Thumb's plant and block conversions can be permissioned individually (e.g. mcmmo.ability.herbalism.greenthumb.plants.wheat, mcmmo.ability.herbalism.greenthumb.blocks.cobblestone). See Permissions for the full list.
