Thresholds and trait multipliers are read from the community wiki's live 42.20.4-stamped pages; per-skill grind numbers come from build42guide.wiki's field testing (checked 2026-08-04 against 42.20.0). We have not re-counted XP in-game on 42.20.4 yet.
The Core Curve Cross-Verified
| Level | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|---|---|---|---|---|---|---|---|---|---|---|
| XP to next | 75 | 150 | 300 | 750 | 1500 | 3000 | 4500 | 6000 | 7500 | 9000 |
Passive Strength/Fitness run their own 1,500 → 150,000 ladder. Skill books apply a level-bracketed multiplier — 3×, 3×, 5×, 5×, 8×, 8×, 12×, 12×, 16×, 16× across the ten levels (recalculated every 10% read) — and VHS tapes cover Aiming, Animal Care, Blacksmithing, Electrical, First Aid, Knapping, Pottery, Tailoring and Welding at community-reported (unconfirmed) rates.
