Configure XP and Skill Multipliers

Adjust experience gain rates and skill multipliers on your Project Zomboid server.

Common Configurations

Fast Progression (Casual)

SandboxVars.lua
XPMultiplier = 3.0,

Players level up 3x faster. Good for servers where you want players to reach higher skills quickly.

Slow Progression (Hardcore)

SandboxVars.lua
XPMultiplier = 0.5,

Half the normal XP rate. Skills take much longer to level, making each point feel more valuable.

Balanced with Head Start

SandboxVars.lua
XPMultiplier = 1.5,
ConstructionBonusPoints = 2,
CookingBonusPoints = 1,
FirstAidBonusPoints = 1,

Slightly faster progression with some starting skill levels so new characters aren't completely helpless.

Max Progression

SandboxVars.lua
XPMultiplier = 10.0,

Extremely fast leveling. Players reach max skills quickly. Good for PVP-focused servers where combat skill matters more than grinding.

Bonus Points Explained

Bonus points give all new characters free skill levels at creation. This is separate from the trait and occupation system.

  • 0 = No bonus (default)
  • 1–3 = Small head start
  • 5+ = Significant advantage from the start

💡 Tip: Bonus points stack with occupation and trait bonuses. A character with Carpenter occupation + 3 bonus Construction points starts very strong.
