Woodcutting

How mcMMO's Woodcutting skill works. chopping logs with an axe. Tree Feller, Leaf Blower, Harvest Lumber, Clean Cuts and Knock on Wood, with the real chances, XP values, durability costs, and the Tree Feller anti-exploit XP reduction.

Woodcutting is the lumberjack skill. You level it by chopping logs with an axe, and in return you get extra drops, the ability to slice through leaves, and the spectacular Tree Feller super ability that brings down an entire tree (and its leaves) in one swing.

Earning XP

You earn Woodcutting XP for each log or wood block you break. The amount depends on the species (Experience_Values.Woodcutting in experience.yml). A sample:

BlockXPBlockXP
Oak Log70Spruce Log80
Birch Log90Acacia Log90
Dark Oak Log90Jungle Log100
Cherry Log105Mangrove Log95
Pale Oak Log130Crimson/Warped Stem35
Shroomlight100Mushroom Stem80
Mangrove Roots10Nether/Warped Wart Block1

"Wood" (bark-on / stripped) variants pay their own (usually slightly lower) values. See experience.yml for the full list. Stripping a log with your axe does not give XP; breaking it does.

Tree Feller: the super ability

Tree Feller is Woodcutting's super ability. When active, breaking a single log destroys the whole connected tree (every log plus the surrounding leaves) in one go, dropping all the loot and XP at once. The locale even calls it "Make trees explode."

Activating it

  1. Hold an axe.
  2. Right-click to ready your axe (you'll get the "tool ready" notification).
  3. Left-click a log within the activation window to fire Tree Feller.

You need mcmmo.ability.woodcutting.treefeller and at least Tree Feller rank 1, unlocked at Woodcutting level 5 (Standard) / 50 (RetroMode). There are 5 ranks (levels 5/25/50/75/100 Standard), which gate how the ability behaves and which non-wood parts get processed.

Duration

duration (seconds) = 2 + (Woodcutting level ÷ IncreaseLevel)
ModeIncreaseLevelLength cap levelMax duration
Standard510022 seconds
RetroMode50100022 seconds

Cooldown

Tree Feller's cooldown is 240 seconds by default (Abilities.Cooldowns.Tree_Feller).

Maximum tree size

A single Tree Feller can process up to Tree_Feller_Threshold = 1000 blocks (config.ymlAbilities.Limits.Tree_Feller_Threshold). If a tree is larger than the threshold, mcMMO aborts with "That tree is too large!" and nothing is felled.

Tool durability and "Splinter"

Tree Feller is hard on your axe. Each log that grants Woodcutting XP costs extra durability equal to Abilities.Tools.Durability_Loss (default 1 per log, on top of normal use). Before felling, mcMMO checks whether your axe can survive the total durability hit:

  • If the axe can't take it, Tree Feller is cancelled and you get the message "YOUR AXE SPLINTERS INTO DOZENS OF PIECES!", and you take a random chunk of damage (up to your current health minus 1). No tree is felled.
  • An Unbreakable axe skips the durability check entirely and is never at risk.

"Splinter" is not a real sub-skill in this version. mcMMO 2.2.054 ships permission and locale entries for Splinter, Bark Surgeon, and Nature's Bounty, but none of them have any implementation in the source. There is no SubSkillType for them. The "Splinter" text you may see is only the failure message above (your axe breaking during Tree Feller), not a separate skill. Treat these three as work-in-progress placeholders.

Leaf Blower: slice through leaves

Once Leaf Blower is unlocked, you can break leaf blocks instantly with an axe (instead of slowly punching through them). It's a simple passive unlock with 3 ranks:

RankUnlocks at (Standard)Unlocks at (RetroMode)
115150
235350
365650

Leaf Blower requires an axe in hand and the mcmmo.ability.woodcutting.leafblower permission. Until you reach level 15, leaves break at vanilla speed.

Harvest Lumber: double drops

Harvest Lumber is your bread-and-butter bonus: a chance for any log you break to drop an extra copy (double drop). It's available from rank 1, which unlocks at Woodcutting level 1, so every Woodcutter has it from the start.

ModeMaxes out at levelMaximum chance
Standard100100%
RetroMode1000100%

The chance scales linearly with your level. From advanced.yml:

Woodcutting:
    HarvestLumber:
        ChanceMax: 100.0
        MaxBonusLevel:
            Standard: 100
            RetroMode: 1000

At level 100 (Standard) every log you chop double-drops. Double drops respect the server's per-block double-drop toggles in config.yml.

Clean Cuts: triple drops (end-game)

Clean Cuts is the mastery tier on top of Harvest Lumber: a chance to drop two extra copies (a triple drop) instead of just one. Its single rank unlocks at Woodcutting level 100 (Standard) / 1000 (RetroMode). It's a true end-game perk.

ModeMaxes out at levelMaximum chance
Standard100050%
RetroMode1000050%
Woodcutting:
    CleanCuts:
        ChanceMax: 50.0
        MaxBonusLevel:
            Standard: 1000
            RetroMode: 10000

Note the MaxBonusLevel of 1000: Clean Cuts keeps scaling well past the normal level 100 cap, reaching its 50% ceiling only at Woodcutting 1000. When a block break checks for bonus drops, mcMMO rolls Clean Cuts first; if it succeeds you get the triple drop, and only if it fails does it fall back to a Harvest Lumber (double-drop) roll. So the two don't stack on the same block.

Knock on Wood: Tree Feller goodies

Knock on Wood only matters during Tree Feller. It improves what the non-log parts of a tree (mostly leaves) give you:

RankUnlocks at (Std / Retro)Effect
130 / 300Saplings/propagules always drop from felled leaf blocks (even the ~75% that normally drop nothing)
260 / 600Adds a chance to spawn bonus XP orbs from non-log tree parts

By default, when Tree Feller knocks down leaves, mcMMO only drops their loot about 25% of the time (a nextInt(100) > 75 check). With Knock on Wood rank 1, any saplings or propagules that would have been suppressed are still dropped. At rank 2, there's a flat 10% chance per non-log tree block to spawn an XP orb (a random 1–99 XP, controllable via advanced.ymlWoodcutting.TreeFeller.Knock_On_Wood.Add_XP_Orbs_To_Drops, default on).

Anti-exploit: reduced Tree Feller XP

Felling a whole tree in one click could hand out a huge XP burst, so mcMMO ships a built-in diminishing-returns rule: ExploitFix.TreeFellerReducedXP (in experience.yml, enabled by default).

With it on, each successive log in a single Tree Feller pays out less:

log XP = max(1, baseLogXP − (logsProcessedSoFar × 5))

So the first log gives full XP, the next gives base − 5, then base − 10, and so on, never dropping below 1 XP per log (unless that log's base XP is 0). This stops players from farming enormous trees purely for the XP spike. Turn the flag off to restore flat, full XP for every log.

mcMMO also tracks player-placed blocks: logs you placed yourself give no Woodcutting XP and are skipped by drops, so you can't farm a tree you just built.
