The game registers each skill with ten XP values and stores each one × 1.5 (PerkFactory.AddPerk) — the numbers above are the stored ones.

How the game scales the XP you earn

Every gain — from an action, a recipe, TV or a tape — passes through the same multipliers (IsoGameCharacter$XP.AddXP), and they stack:

Your starting levels in the skill

none → ×0.25 · skills you start with no levels in (not Fitness, Strength or Running)
+1 → ×1 · Running: ×1.25
+2 → ×1.33
+3 or more → ×1.66

Starting levels come from the occupation and traits picked at character creation — plan them in the trait planner.

Traits

Fast Learner → ×1.3 · every skill but Fitness and Strength
Slow Learner → ×0.7 · every skill but Fitness and Strength
Crafty → ×1.3 · the Crafting skills
Pacifist → ×0.75 · weapon skills and Aiming

Then the book you are reading, if your level is in its range, and the sandbox “XP multiplier” — 1 in every preset.

The no-levels rule matters most: a skill you start with no levels in earns a quarter of the XP, so a single starting level in a skill you mean to train makes it learn four times as fast (Fitness, Strength and Running are spared).

Skill book multipliers

Each series has five volumes covering levels 1–2, 3–4, 5–6, 7–8 and 9–10. The multiplier applies to XP earned while your level is in the volume's range, in full once the whole book is read:

Skills	Vol 1	Vol 2	Vol 3	Vol 4	Vol 5
21 skills (all others)	×3	×5	×8	×12	×16
Long Blade, Aiming, Reloading	×1.5	×2.5	×4	×6	×8

All 35 skills

By category; sort by books, recipes or the XP TV and tapes give. Each picture is the skill's first book, or the first thing it lets you make.
