Levels are not XP points
Your XP bar fills with points; each level-up requires more points than the last. The anvil charges in levels, so the points you actually spend depend on your current level. Spending 3 levels at level 40 costs far more points than 3 levels at level 10.
The level-to-points formula
- Levels 0-16: each level costs (level^2 + 6*level) points.
- Levels 17-31: each level costs (2.5*level^2 - 40.5*level + 360) points.
- Levels 32+: each level costs (4.5*level^2 - 162.5*level + 2220) points.
Why this matters for god gear
A god-sword recipe might cost 30-39 levels. If you are level 45, those levels represent tens of thousands of XP points - a big chunk of grinding. This is exactly why the optimal anvil order matters: every level saved is a large number of points you don't have to farm. The calculator shows both the level cost and the minimum XP points for the whole recipe.
Practical XP farming for enchanting
- Enderman or hostile-mob farms: thousands of points per hour.
- Blaze rods + bottle o' enchanting: instant, trade-friendly XP.
- Mining quartz/ancient debris: XP while gathering resources.
- Breeding animals (pre-farm): cheap early-game XP.
