Mob Kill XP

Overview

Mob Kill XP controls how much experience offensive weapon skills earn when you kill a mob. Kill XP is used by the Damage+Kill and Kill-Only combat XP modes. In Damage+Kill mode (the default), kill XP is awarded as a bonus on top of per-hit damage XP. In Kill-Only mode, it is the sole source of offensive weapon XP.

Mob XP values are stored in mods/mmoskilltree/mob-kill-xp.json using an override-based system. The file only contains your customizations — defaults are built into the mod and auto-update with new versions.

Kill XP Formula

When Weapon XP Scaling is enabled (default):

Kill XP = Mob Base XP x (100 + Weapon XP) / 100

The weapon's per-hit XP value (from XP Maps) acts as a percentage bonus on the mob's base XP. For example, a sword with 70 per-hit XP grants a 70% bonus — killing a Trork (65 base XP) yields 65 x 170 / 100 = 110 XP.

When Weapon XP Scaling is disabled:

Kill XP = Mob Base XP only

Weapon quality has no effect — all weapons award the same XP for the same mob. Toggle this from the Mob Kill XP admin page.

Pattern Matching

Mob type IDs use longest substring matching. When a mob is killed, its type identifier (e.g., Skeleton_Fighter) is checked against all patterns. The longest matching pattern wins:

• Skeleton matches Skeleton_Fighter, Skeleton_Archer, Skeleton_Burnt, etc.
• Skeleton_Burnt is more specific — takes priority over Skeleton
• Wolf matches Wolf, Wolf_Arctic, etc.
• Empty string "" is the fallback — matches any mob with no better match

Default XP Tiers

Over 100 mob types have built-in XP values organized by difficulty:

File Structure

{
  "schemaVersion": 1,
  "weaponXpScaling": true,
  "overrides": {
    "Skeleton": 80,
    "Dragon": 600,
    "Chicken": -1
  }
}

• schemaVersion — Config format version (do not change)
• weaponXpScaling — Whether weapon quality acts as a percentage bonus on kill XP
• overrides — Your customized mob XP values (only stores changes from defaults)

Special Values

• -1 — Disable a pattern (mob gives no XP on kill)
• 0 — Pattern gives zero XP (still processed)
• Positive number — Base XP awarded for killing a matching mob

Admin UI

Access the visual editor via /mmoadmin → Mob Kill XP:

• Browse all mob patterns with default and current values
• Status indicators: Default (green), Override (orange), Disabled (red)
• Click a pattern name to copy it to the edit field
• Add/Update — Set or change XP for a pattern
• Disable — Set a pattern to -1 (no XP)
• Reset — Revert a single pattern to its default
• Trim Overrides — Remove overrides that match their default values
• Weapon XP Scaling toggle — Enable/disable weapon quality bonus

Reference Files

Check mods/mmoskilltree/_reference/defaults-mob-kill-xp.json for all default mob XP values. This file is auto-generated and read-only — use it as a reference when creating overrides.

Best Practices

• Use specific patterns for variants that should differ from their base type (e.g., Skeleton_Burnt at 85 XP vs Skeleton at 65 XP)
• The fallback pattern (empty string) catches any mob without a specific entry — set it to control the baseline
• Use Trim Overrides periodically to clean up overrides that match defaults
• When adding custom mobs, use the mob's type identifier as the pattern
• Back up mob-kill-xp.json before major changes
