Lumberjacking

There is a particular satisfaction in felling a tree with an axe you forged yourself — and a particular profit, since carpenters and fletchers buy everything you can carry.

Stats: Strength (primary), Dexterity (secondary) · Title: Lumberjack

How it works

Use any axe on a tree. Per Scripts/Services/Harvest/Lumberjacking.cs:

Trees hold wood in 4×4-tile banks (BankWidth = 4).
Each successful chop yields 10 logs (ConsumedPerHarvest = 10).
Cut logs into boards with an axe (boards weigh less and crafting wants them).

Wood types and required skill

Log	Required skill (chop)	Vein chance	Board-cutting skill*
Ordinary	0	49%	0
Oak	65.0	30%	65
Ash	80.0	10%	80
Yew	95.0	5%	95
Heartwood	100.0	3%	100
Bloodwood	100.0	2%	100
Frostwood	100.0	1%	100

* Board-cutting accepts Carpentry or Lumberjacking at the listed value (Scripts/Items/Resource/Log.cs, TryCreateBoards).

Chopping also turns up ML bonus resources at 100 skill (bark fragments 10%, luminescent fungi 3%, switches 2%, parasitic plants and brilliant amber 1% each).

The axe damage bonus

Lumberjacking is secretly a combat skill — but only with an axe in hand. When a hit lands, ScaleDamageAOS (the active damage path on this AOS/EJ shard) adds:

lumberBonus = Lumberjacking × 0.2%   (+10% extra at exactly 100.0)   → +30% at GM
if (weapon Type != Axe) lumberBonus = 0      // axes only

It scales linearly: ~+0.2% damage per point, with a flat +10% jump at GM, for +30% at 100 Lumberjacking (GetBonus(Lumberjacking, 0.2, 100, 10)).
Axe-only. The bonus is zeroed unless the weapon’s type is Axe — i.e. a weapon that inherits BaseAxe (the whole Axes family: hatchet, war axe, battle axe, double axe, large/two-handed axe, executioner’s axe, ornate/heavy ornate axe, and the gargish axes). Swing a sword, mace, or bow and Lumberjacking adds nothing.
It’s added to the other melee bonuses, then multiplies base damage: damage = base × (1 + Tactics% + Anatomy% + Str% + Lumber%). For an axe warrior at GM Tactics + GM Anatomy + GM Lumberjacking + 100 Str that’s 1 + 0.6875 + 0.55 + 0.30 + 0.35 = **×2.8875** — the highest pure-skill melee multiplier in the game, which is exactly why the axe-lumberjack is a classic damage build.
Worked example: a 15-base-damage battle axe, GM Tactics+Anatomy+Lumber+100 Str → ~43 before item Damage Increase. The same swing with a non-axe loses the +30% (×2.5875 → ~39). Axes use the Swordsmanship skill, so this pairs with Swords + Tactics + Anatomy.

The full melee damage stack is laid out in Advanced combat → Damage components.

Training

0–10: buy from an NPC who knows it (a trainer teaches up to one-third of its own skill, capped at 42.0 — Scripts/Mobiles/Normal/BaseCreature.cs, CheckTeach: baseToSet = ourSkill.BaseFixedPoint / 3) or just chop — every use gains below 10.0.
10–100: chop trees in a loop — it’s a pure resource grind and GGS carries it. Standard gain rules apply; anti-macro is off, and GGS guarantees slow-but-steady progress at high skill. Strength trains alongside (primary stat), which also raises your carry capacity for hauling logs. See using & training skills.

Where

Yew — the forest is the town. Also: forests north of Britain, east of Skara Brae, and west of Vesper (per world_knowledge.yaml).
