Mathematical Formulas

In 0.2.0, XP and progression use a monster-level-based system with level-difference multipliers and zones. This replaces the previous health-based XP formula.

How the New System Works

Your XP gains depend on two main factors:

Monster level - Base XP scales with the monster’s level (higher level = more base XP).
Level difference - How close the monster’s level is to yours. Fighting monsters near your level gives the best XP; farming much easier or much harder content is heavily penalized.

XP Gain from Mobs

Base XP (Monster Level)

Base XP is determined by the monster’s level:

Base XP ≈ MonsterLevel × √MonsterLevel   (conceptually; implementation may use level² scaling)

Monster Level	Approx. Base XP
1	~1
50	~353
81	~729
100	~1,000

Higher-level monsters give more base XP.

Level Difference Multiplier

The difference between your level and the monster’s level applies a multiplier:

Your Level vs Monster Level	Multiplier	Result
Same level (±0)	1.5×	Best XP!
1–5 levels higher	1.1× – 1.5×	Great XP
6–25 levels higher	1.0×	Normal XP
26–30 levels higher	0.5×	Reduced (50% penalty)
31–40 levels higher	0.4×	Low (60% penalty)
41–50 levels higher	0.3×	Very low (70% penalty)
51+ levels higher	0.2×	Minimal (80% penalty)
1–5 levels lower	1.4× – 1.0×	Good XP
6–25 levels lower	0.96× – 0.2×	Decreasing XP
26+ levels lower	0.1×	Very low (90% penalty, trivial content)

You can disable the underleveled XP penalty (rows where the monster is higher than you) via EnableGapLevelXpReducer: false in config - you will get full XP (1.0×) from higher-level monsters. See Configuration or Difficulty Scaling. Best strategy: Fight monsters within ±25 levels of your level. Same-level or slightly higher (±5) gives the highest bonuses.

Final XP Formula

Final XP = Base XP(monster level) × Level Difference Multiplier × RateExp × ZoneRateExp

Variable	Description
Base XP	From monster level (see table above)
Level Difference Multiplier	From your level vs monster level (see table)
RateExp	Global XP rate from RPGLevelingConfig (default 1.0; e.g. 2.0 = double XP)
ZoneRateExp	Per-zone XP multiplier from ZoneLevelConfig (default 1.0; e.g. 2.0 = double XP in that zone, 0.5 = half). Applied to mob kills and block break XP in the zone.

Example (Level 81 vs Level 81 monster, RateExp 3.0, ZoneRateExp 1.0):
Base 729 × 1.5 × 3.0 × 1.0 = ~3,281 XP per kill.

Zones and Monster Level Ranges

The world is divided into zones with different monster level ranges:

Zone	Name	Monster Levels	Best For
1	Emerald Grove	1 – 25	Early game (Level 1–30)
2	Howling Sands	25 – 50	Mid game (Level 20–55)
3	Borea	50 – 75	Late game (Level 45–80)
4	Devastated Lands	75 – 100	End game (Level 70–100)
5	Skylands	85 – 100	Max level
6	Poisonlands	90 – 100	Ultimate challenge

Monster Level Variation (±5)

Monsters in a zone have ±5 level variation around their base. Same zone, same “type” of monster can be different levels (e.g. 30, 33, 37, 40). This adds variety and keeps combat less predictable.

Zone Colors on the HUD

The HUD shows the current zone and its color based on how it fits your level:

Color	Meaning	XP	Action
White	Too easy (−26+ levels)	10% (90% penalty)	Move to a harder zone
Green	Good match (±25 levels)	100–150% (full + bonuses)	Stay here
Orange / Red / Purple	Too hard (+26+ levels)	20–50% (50–80% penalty)	Come back when higher level

Pro tip: If the zone name is green, you’re in the right place for the best XP.

XP Required for Level

Total XP required to reach a level:

XP_required = LevelBaseXP × level^2.5 + LevelOffset   (level ≥ 2)
XP_required(1) = 0

The exponent 2.5 (not squared) gives a steeper curve: easier early levels, much harder at high levels.

Variable	Description
level	Target level
LevelBaseXP	Base for level formula (default 150.0 in config; examples below use 50.0)
LevelOffset	Added to total XP per level. Only affects XP needed for 1→2; for 2→3 and beyond it cancels out when taking the difference.

Examples (LevelBaseXP = 50.0, LevelOffset = 0.0):

Level	XP Required
1	0 (starting)
2	283
10	15,811
50	883,884
100	5,000,000

XP Needed for Next Level

XP_needed = XP_required(level + 1) - XP_required(level)

Progression and Monsters per Level

Approximate monsters to kill per level when fighting same-level monsters (RateExp 3.0, LevelBaseXP 150, default formulas). “XP per level-up” is the range for one level step in that band (e.g. 1→2 needs ~850 XP, 9→10 needs ~10,500 XP). Total XP to go 1→10 is much higher (~47,400).

Level Range	XP per level-up (min – max)	XP per Kill	Monsters per level-up
1 → 10	849 – 10,984	4.5 – 122	189 – 90
20 → 30	34,809 – 60,089	403 – 703	86 – 85
50 → 60	134,566 – 172,496	1,591 – 2,039	85
80 → 82	270,849 – 277,111	3,220 – 3,281	84
90 → 100	326,656 – 372,192	3,845 – 4,433	85 – 84

Total (1 → 100, same-level farming): ~9,000 – 12,000 monsters (order of magnitude), depending on exact rates and level choices.

XP from Mining and Woodcutting

0.2.3+: You can earn XP from breaking blocks:

Mining XP: Blocks whose ID contains ore or mineral (e.g., Iron_Ore, Diamond_Mineral)
Woodcutting XP: Blocks whose ID contains log or tree (e.g., Oak_Log, Birch_Tree)

Note: Stone, rock, wood, and plank blocks do NOT give XP (but still benefit from Mining/Woodcutting stat speed bonus).

Block XP Formula

Block XP = BaseBlockXP × PlayerScale × ZoneMultiplier × RateExp

Variable	Description
BaseBlockXP	From config: `BlockXPBaseMining` (default 5.0) or `BlockXPBaseWood` (default 3.0)
PlayerScale	`1.0 + (playerLevel - 1) × BlockXPPlayerLevelFactor` (no cap). Factor default 0.1 (see Main Config).
ZoneMultiplier	`1.0 + (zoneLevelMid - 1) × BlockXPZoneLevelFactor`, capped at 1.5
RateExp	Global XP rate from config (same as mob XP)

Zone Bonus for Blocks

Mining/woodcutting in higher-level zones gives more XP. Each zone can have its own BlockXPZoneLevelFactor in Zone Config:

Zone	ZoneLevelMid	BlockXPZoneLevelFactor	Zone Multiplier
Zone 1 (L1-15)	8	0.005	1.035×
Zone 2 (L15-50)	32	0.005	1.155×
Zone 4 (L75-100)	87	0.005	1.43×

Example

Player level 50, mining ore in Zone 3 (L50-75, zoneLevelMid=62), RateExp=3.0, BlockXPPlayerLevelFactor=0.1:

BaseBlockXP = 5.0 (mining)
PlayerScale = 1.0 + (50-1) × 0.1 = 5.9 (no cap)
ZoneMultiplier = 1.0 + (62-1) × 0.005 = 1.305
Block XP = 5.0 × 5.9 × 1.305 × 3.0 ≈ 115.4 XP per ore

At level 80 (no zone bonus, factor 0.1): PlayerScale = 1 + 79×0.1 = 8.9 → ~133 XP per ore (mining, base 5, rate 3). See Main Config for EnableBlockXP, BlockXPBaseMining, BlockXPBaseWood, BlockXPPlayerLevelFactor.

Stat Points

Same as 0.1.9:

Stat points per level: 3 (configurable)
Max level: 100
Total at max: (100 − 1) × 3 = 297 stat points

See Configuration for StatPointsPerLevel, StatValuePerPoint, and related options.
