Build 42.19 · skill names, effects, XP sources, starting boosts, and skill-book coverage

At a glance Full character-skill index for Build 42.19: display name, effect text, practical XP sources, and whether a skill book exists. For deep craft trees, use the linked guides (farming, forging, firearms, and so on).
Build 42 skills & common XP myths B42 includes skills many older lists miss: Blacksmithing, Butchering, Carving, Knapping, Glassmaking, Animal Care, Masonry, Pottery, and Tracking. Also: Aiming XP scales with hit count (×2.7 below level 5), not total damage; Nimble XP comes from moving while aiming, not fence-hopping; First Aid XP comes from treatment actions—not from injuring yourself on purpose.

Passive

Skill What it does How XP is earned Skill book
Fitness Increases melee attack speed, and speed and success chance of climbing. Decreases exhaustion rate. Exercise menu (Health panel); chance XP while running/sprinting with usable endurance; chance XP on successful non-ranged hits while endurance is still high. Can also decay with long inactivity depending on sandbox. No
Strength Increases melee attack damage and knockback and your inventory encumbrance limit. Reduces muscle strain. Exercise menu; chance XP while moving at over ~50% max carry weight; XP for hitting trees with a non-bare-hands weapon; XP equal to last hit count on non-ranged multi-hits. Can decay with long inactivity. No

Deep dive: fitness training guide. Higher Strength also helps with melee weapon damage and knockback.

Agility

Skill What it does How XP is earned Skill book
Running Increases how quickly you move when running. Chance XP while jogging or sprinting with usable endurance (same move timing as Fitness chance rolls). No
Lightfooted Decreases the noise of your footsteps, whether running, walking, or crouching. Mainly quiet movement around zombies. Some Life and Living / media skill lines can also help. Details: Lightfooted guide. No
Nimble Increases how quickly you move when in a “combat stance”, and decreases footstep noise. Move while aiming (combat aim mode). XP only rolls when your position actually changes—standing still while aiming does not farm it. Fence climbing is not the current Nimble XP path. No
Sneaking Decreases the distance at which zombies spot you and the sound of your footsteps while crouching. Crouch/sneak near zombies without being spotted; higher levels make quiet approaches safer for early looting. No

Combat

Weapon skills share a common pattern: use weapons of that category in successful hits. Maintenance reduces weapon condition loss; it gains XP from qualifying melee hits and from many Build 42 repair, sharpening, assembly, and improvised-equipment recipes.

Skill What it does How XP is earned Skill book
Axe Increases attack speed and damage when using axe-type weapons, and reduces their muscle strain. Hit zombies (or valid targets) with axe-category weapons. Melee weapon XP uses a damage-based amount with a low per-hit cap (not unlimited raw damage). No
Long Blunt Increases attack speed and damage when using long blunt weapons, and reduces their muscle strain. Hit with long blunt weapons (bats, crowbars, etc.). See also long blunt weapons. No
Short Blunt Increases attack speed and damage when using short blunt weapons, and reduces their muscle strain. Hit with short blunt weapons. No
Long Blade Increases attack speed and damage when using long blade weapons, and reduces their muscle strain. Hit with long blade weapons. Has skill books with lower multipliers than most craft books (1.5 / 2.5 / 4 / 6 / 8). Yes (reduced mult.)
Short Blade Increases attack speed and damage when using short blade weapons, and reduces their muscle strain. Hit with short blade weapons. No
Spear Increases attack speed and damage when using spear-type weapons, and reduces their muscle strain. Hit with spear-category weapons. No
Maintenance Decreases the chance of melee weapons being damaged. Trained through melee combat. Qualifying melee hits can award Maintenance XP separate from actual condition loss: often a small fixed amount, or less when the weapon is already very durable. Shoves, stomps, weapons that never grant Maintenance XP, and some badly held two-handed attacks do not qualify. Repairing or sharpening gear, assembling spears, and crafting many improvised weapons or tire-armor pieces can also award Maintenance XP directly. See maintenance leveling and weapon repair. Full skill-book multipliers (3–16). Yes

Firearm

Skill What it does How XP is earned Skill book
Aiming Increases your chance of hitting a target with firearms, and of doing extra damage. Score hits with ranged weapons. Base XP = number of targets hit that shot. Below level 5, that amount is multiplied by 2.7. It is not “total damage dealt.” Shotguns still excel early because they often hit more targets per shot—not because of a separate damage formula. Books use reduced multipliers (1.5–8). Yes (reduced mult.)
Reloading Increases the speed you reload firearms and magazines. Trained by reloading firearms. Reload actions: insert magazine, load rounds into magazine, and related reload steps. Below level 5 those actions grant more XP. Books use reduced multipliers (1.5–8). Yes (reduced mult.)

Crafting

Most craft skills level by completing recipes, builds, dismantles, or repair actions that award that perk. Prefer reading the matching skill book before grinding when the volume is high.

Skill What it does How XP is earned Skill book
Carpentry Allows the building of wooden constructions. Build and disassemble wooden furniture/constructions; some barricade actions grant a little Carpentry XP without skill-book multipliers. Guides: carpentry, fast leveling. Yes
Cooking Allows the creation of more nutritious and delicious food. Cook food and craft food recipes (including evolved recipes). Making food items can award Cooking XP. See cooking guide. Yes
First Aid Increases the available information for injuries, and the quality of medical treatments. Treatment actions grant XP—not “dig dirt barehanded.” Examples: bandage (~5), clean burn (~10), stitch/splint/remove glass (~15), remove bullet (~20). Self-inflicted wounds only create medical work; they are not a safe or recommended grind. Guides: first aid, medical supplies. Yes
Electrical Allows the creation and maintenance of electrical devices. Dismantle electronics and complete electrical recipes/repairs (including generator work at higher levels). Guide: electrical skill. Yes
Welding Allows the building of crude metal barricades and objects. Metalworking recipes and dismantling with a propane torch. Related: metalworking tips, B42 metalworking overhaul. Yes

Butchering Increases the quality of meat harvested from animals. Butchery pipeline: processing carcasses on hooks, removing heads, leather, meat, and related steps (Butchering XP on those actions). Yes

Survival

Skill What it does How XP is earned Skill book
Fishing Increases your chance of catching a fish, the quality of your catches, and makes your fishing equipment less likely to break. Catch and pick up fish (larger fish grant more XP); checking fishing nets also grants small XP. Season, bait, and gear still matter. Guide: fishing. Yes
Trapping Increases the chances of catching an animal in a trap, and allows better traps to be crafted. Harvest successful traps (animals or valid catches). Building traps alone is not the main XP path. Guide: animal traps. Yes
Foraging Increases the quality of items found using Search Mode, available search categories, and the search radius. Enter Search Mode and collect forage finds. Higher levels unlock more categories and better finds. Guide: foraging. Winter stockpiles still matter for winter. Yes
Tracking Increases the available information on wild animal clues found in Search Mode, and allows smaller clues to be found. Inspect animal tracks and use Search Mode for wildlife clues; higher Tracking shortens inspect times and reveals more detail. Yes

Sandbox skill multipliers

Custom sandboxes expose per-skill XP multipliers for all 35 skills listed above (plus a global multiplier toggle). Defaults on Apocalypse-style presets are typically 1.0 per skill unless you change them. Raising multipliers accelerates leveling but softens the progression the game balances around.

FAQ

How many skills does Build 42.19 have?

The sandbox multiplier list exposes 35 player skills (including the nine B42-era trades such as Blacksmithing and Tracking). Category headers in the skills UI are not separate leveled skills.

Is Aiming still best trained with shotguns?

Shotguns remain strong early because XP is based on how many targets that shot hit, with a 2.7× factor under level 5. They are not special-cased for “total damage XP.” Noise and ammo cost still matter.

Do I level Nimble by climbing fences?

No. Current rules award Nimble when you move while aiming and your tile position changes. Fence climbs can still be useful movement, but they are not how Nimble XP is granted.

Should I hurt myself to level First Aid?

No. XP is granted by treatment actions (bandage, stitch, remove glass/bullet, splint, clean burn, etc.). Self-injury wastes health and supplies and is not required.

Why do skill names look different on older guides?

Build 42 renamed several skills in the character UI. Common renames: Sprinting → Running, Farming → Agriculture, Metalworking → Welding, Husbandry → Animal Care, Flint Knapping → Knapping, Blacksmith → Blacksmithing. This page uses the current in-game names.
