Companion Mods & Content Packs | MMO Skill Tree Docs

Overview

MMO Skill Tree ships as a small core jar plus an ecosystem of separate downloads. One of them is not optional. The rest are additive: install the ones you want, skip the rest, in any combination.

ZiggfreedCommon (required)

Every server running MMO Skill Tree 1.4.0 or newer needs ZiggfreedCommon installed alongside it. This is not a content pack, it adds no quests or items, and it does nothing visible on its own.

ZiggfreedCommon

Required

Shared, mod-agnostic Hytale primitive and framework library: 3D sound, camera shake, HUD/toast primitives, the branching NPC dialogue engine, the UI retint/theme engine, and the shared cast/ability runtime kernel the MMO jar links against at compile time. Zero gameplay of its own.

Requires: Hytale server only (no other mod dependency); pin: 1.4.0

CurseForge Installation

Load order matters

The Hytale server loads ZiggfreedCommon before the MMO Skill Tree jar. Drop ZiggfreedCommon-1.4.0.jar into the same Mods/ folder as MMOSkillTree-1.5.2.jar; without it the MMO jar cannot fully initialize. It is never bundled inside the MMO jar and never shipped as part of a content pack. One copy covers every mod on the server that needs it (MMO Skill Tree, MMO Mob Scaling, and Kweebec Nightmare all depend on it).

Official content packs

Each pack is a standard Hytale asset pack (a .zip dropped into Mods/), built with IncludesAssetPack: true, additive on top of the base mod. None of them require Java or a server restart beyond the normal mod-load cycle.

MMO Skill Bounty Pack

Content Pack

Rotating bounty boards (daily, weekly, quick contracts), the Bounty Token currency, a Token Shop with a per-skill XP Exchange, placeable board/trader blocks, and the Adventurer's Guide hub NPC.

Requires: MMO Skill Tree 1.4.3+

CurseForge Bounty Board docs

MMO Skill Quest Pack

Content Pack

Two hand-authored zone questlines for Orbis: the Emerald Wilds starter campaign and the tougher Howling Sands follow-up, each with its own auto-spawning quest-giver NPC and branching dialogue.

Requires: MMO Skill Tree 1.4.0+

CurseForge Quests docs

MMO Skill Mastery Pack

Content Pack

The mastery and currency systems: 20 spendable mastery progression tracks, the mastery-point and life-essence currencies, and matching quests/achievements. The Mastery and Currency menu tabs stay hidden without it.

Requires: MMO Skill Tree 1.1.0+ (functionally needed for the full mastery feature set)

CurseForge Mastery docs

MMO Skill Taming Pack

Content Pack

Quests, achievements, and level rewards for the Taming skill. The skill itself only activates once the separate, third-party Alec's Animal Husbandry mod is also installed.

Requires: MMO Skill Tree base plugin, plus Alec's Animal Husbandry for the Taming skill to activate

CurseForge Custom Skills docs

MMO Skill Capes Pack

Content Pack

A pure cosmetic asset pack: the same 20 mastery cape items MMO Skill Tree already bundles internally, for cosmetic-only servers running no plugin at all.

Requires: None (standalone; do not install alongside the MMO Skill Tree plugin, which already ships these capes)

Item Rewards docs

Never install both cape sources

MMO Skill Tree bundles the mastery cape items internally and grants them automatically at skill level 100. Installing the standalone MMO Skill Capes Pack on the same server causes duplicate item and translation ID warnings at load. Only use the standalone pack on a server that is not running the MMO Skill Tree plugin.

Standalone companion mods

These are independent Hytale mod jars, not content packs. Each has its own version numbers, its own install requirements, and works with or without MMO Skill Tree installed (with reduced functionality when it is absent).

MMO Mob Scaling

Companion Mod

Scales open-world mob difficulty to the players around them: native zone/biome floors, distance-from-spawn escalation, and a rarity ladder (Rare/Epic/Legendary/Boss) with affixes and bonus loot. Reads player power only through the frozen MMOSkillTreeAPI (getPowerLevel, statRewardSum, getCombatLevel). This is the current replacement for the built-in Elite Mobs system, which was removed in 1.5.0.

Requires: MMO Skill Tree 1.5.0+, ZiggfreedCommon 1.4.0+ (both hard dependencies)

CurseForge Configuration docs

MMO Mob Scaling is a separate, standalone, optional companion mod with its own CurseForge listing and its own version numbers. It is under active development; treat any specific version or feature claim about it as subject to change until confirmed on its own release page.

Kweebec Nightmare

Companion Mod

A standalone co-op horror minigame with zero MMO dependency: relight corrupted shrines to escape a Void-corrupted grove while a hunter closes in, or defend a heart-sapling through waves of Blighted Kweebec. Runs fully on its own; if MMO Skill Tree is also installed, surviving a night feeds MMO skill progression through optional hooks.

Requires: Perfect Utils and ZiggfreedCommon (both required); MMO Skill Tree is optional

Install order

For a server running the full official stack:

1
Install ZiggfreedCommon
Required for MMO Skill Tree 1.4.0+, and for either standalone companion mod above.
2
Install the MMO Skill Tree jar
The base plugin.
3
Install the content packs you want
Any order among themselves; each is independently optional and additive. Skip the Capes Pack if the base plugin is already installed.
4
Optionally install one or both companion mods
Kweebec Nightmare needs Perfect Utils and ZiggfreedCommon. MMO Mob Scaling needs MMO Skill Tree 1.5.0+ and ZiggfreedCommon 1.4.0+.

All of the above target the same Hytale server range as the base mod (>=0.5.0-pre.0 <0.6.0, "Update 5").

Author your own pack

Any of the official packs above are built the same way a server owner or content creator can build their own: a data-only Hytale asset pack, no Java required. See Content Packs to get started.
