Woodcutting

Woodcutting is a skill that is based around chopping trees down with an axe. Levelling the skill gives you increased chances of extra wood dropping from trees, as well as extra duration on the tree feller ability.

Tree Feller
Locked until level 5 woodcutting

Make trees explode

Tree Feller is an active skill that allows you to chop down entire trees by only breaking one block. To use Tree Feller, right-click while holding an axe to ready your tool. With the tool ready, chop a block of wood or giant mushroom to activate the skill. Tree Feller only breaks blocks at the same height and higher than the block that is chopped, so cutting the middle of a tree will leave a stump. At level 0, tree feller is unavailable, it unlocks at level 5, and it increases by 1 second every 5 levels. This gives it a max duration of 22 seconds at level 100. The ability has a cooldown between uses that lasts 240 seconds (4 minutes). Tree feller does not break trees larger than 500 blocks by default and at lower levels, it breaks much less.

When using Tree Feller, the durability of one's axe will be decreased by as much as if each log/huge mushroom block had been broken individually. If one's axe should break while Tree Feller is active, the user will suffer eight damage and a message will appear reading, "Your axe splinters into dozens of pieces!". The surrounding logs/huge mushroom blocks will remain intact, apart from the one on which the axe was broken.

Leaf Blower
Blow away leaves Locked until level 15 woodcutting

Leaf Blower is an ability that will cause leaf blocks to break instantly when hit with an axe. When destroyed using Leaf Blower, a leaf block has a 10% chance of dropping its respective sapling. The leaves do durability damage to the axe and make a popping sound when broken.

Harvest Lumber
Harvest Lumber is a passive skill that allows you to gain two items instead of one when chopping any log or giant mushroom block that was either generated by the world or grown. The chance to get double drops increases by 0.1% per level to a maximum of 100% at level 1000.

Knock on Wood
This ability gives you goodies (saplings, xp orbs, apples, etc) when using Tree Feller. Tree Feller no longer gives non-wood items by default, it now requires Knock on Wood for additional loot.

Levelling

 * Create a large grove of birch trees, then chop down and replant as many trees as possible. This is because birch trees will not grow into the big trees that oak saplings can grow into, allowing for an easier time cutting down the trees when Tree Feller is on cooldown.
 * Create a mushroom tree by using bone meal on mushrooms planted on dirt, coarse dirt, grass blocks, rooted dirt, moss blocks, mycelium, nylium, or podzol. Mushrooms can be planted on mycelium, nylium, or podzol at any light level.
 * Most compactible tree to grow is spruce trees without letting the trees too big for tree feller to work. Put two blocks between each spruce tree.
 * 2x2 spruce trees have the best advantage of being able to cut down the entire tree easily, with or without Tree Feller.
 * Cut trees using an Efficiency V axe and run with speed potions to maximize the number of trees you can cut down during a single duration of Tree Feller.
 * Haste II Potions can be brewed from the Alchemy skill after level 125 Alchemy. They'll allow you to cut down trees faster.
