PMMO x Cataclysm Compat

If you're running Project MMO with L_Ender's Cataclysm, the Cataclysm entities show up with no XP values and no skill gates. This mod fills that in. Kills on every boss, mini-boss, and regular mob now reward combat and endurance, and fighting a Maledictus or Scylla requires the levels you'd expect.

What it does

Pure data. No Java behavior, no mixins, no asset overrides. Just JSON files under data/cataclysm/pmmo/entities/ wrapped as a Forge mod for modpack compatibility. Three tiers:

• 8 bosses, end-game XP and high level gates
• 8 mini-bosses, mid-tier values for dungeon and arena fights
• 21 regular mobs, baseline XP for the common encounters

Supported entities

Bosses:

• Netherite Monstrosity
• Ender Guardian
• The Harbinger
• Ancient Remnant
• The Leviathan
• Scylla
• Maledictus
• Ignis

Mini-bosses:

• Ender Golem
• The Prowler
• Kobolediator
• Wadjet
• Amethyst Crab
• Clawdian
• Aptrgangr
• Ignited Revenant

Regular mobs:

• Endermaptera
• Deepling
• Deepling Brute
• Deepling Angler
• Deepling Priest
• Deepling Warlock
• Coral Golem
• Coralssus
• Lionfish
• Ignited Berserker
• The Watcher
• Koboleton
• Draugr
• Royal Draugr
• Elite Draugr
• Brontes
• Drowned Host
• Hippocamtus
• Storm Serpent
• Symbiocto
• Urchinkin

XP scaling

Bosses pay out enough to feel like a milestone. Mini-bosses sit a tier below, big enough to matter but not enough to substitute for the bosses themselves. Regular mobs are baseline grind value. Damage XP scales with tier too, so smacking a Draugr 100 times doesn't equal one boss kill.

The numbers above are just the kill bounty. PMMO also awards combat XP on every hit landed, so total per-kill combat XP scales with mob HP. Tougher mobs like the Ender Golem and Coralssus naturally pay out more than the base value since they take more hits. Endurance is earned from damage taken plus a smaller bonus on kills, not from damage dealt.

Requirements

Minecraft 1.20.1, Forge 47.x. Project MMO and L_Ender's Cataclysm are soft dependencies, so the mod won't crash if either is missing. The JSON just won't apply.

Compatibility notes

Server-side. Clients don't need it for the mod to function, though installing it on both is fine. Safe to add or remove on existing worlds since nothing is persisted to world data. No textures, no models, no recipes touched.
