Companion Mods & Content Packs
Everything that installs alongside the base MMO Skill Tree jar: one required library, official content packs, and optional standalone mods
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.
The Adventurer's Guide hub NPC ships as a built-in NPC placement in the jar itself, not as part of any pack - manage it live with /mmonpc.
ZiggfreedCommon (required)
Every server running MMO Skill Tree needs ZiggfreedCommon 2.0.1 or newer installed alongside it. It is not a content pack and it ships no quests, items or worlds of its own, but it is more than plumbing: it carries the engines behind quests, achievements, requirements, conversations, placed NPCs, the whole economy and the placed-block ledger, keeps the one progress record per player those engines write, draws the in-world tracked-quest HUD, ships a neutral default for each of the seven feedback moments, and registers two command families and a folder of its own. A stale ZiggfreedCommon jar fails the boot up front, naming the version MMO Skill Tree needs, instead of a confusing class error partway through startup.
ZiggfreedCommon
The shared engine library: the quest and achievement runtime and its one progress record per player, the one requirements block, the dialogue engine, NPC placement, wallets and storefronts and boards, the feedback-moment engine with a neutral default file for each of the seven moments, the in-world tracked-quest HUD, shared loot tables, the placed-block ledger, plus the primitives the MMO builds on (3D sound, camera shake, toasts, the UI theme engine, the ability runtime). Registers /zigcommerce and /zigprogress (the MMO's /mmoshop, /mmobounty, /mmocurrency, /mmoquestadmin, /quest and /mmoachadmin are aliases over them), keeps its owner files under mods/ziggfreedcommon/, and ships neutral default words for shop shelves, board grades and the seven moments in all nine languages.
Requires: Hytale server only (no other mod dependency); pin: 2.0.1
Load order matters
ZiggfreedCommon jar into the same Mods/ folder as the MMO Skill Tree 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, RPG Stations, 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.
The packs need MMO Skill Tree 1.6.0
MMO Skill Bounty Pack
Rotating bounty boards (Daily, Weekly, and a fast two-hour Bihourly board), the Bounty Token currency, a Token Shop with a per-skill XP Exchange, and placeable board/trader blocks.
Requires: MMO Skill Tree 1.6.0+
MMO Skill Quest Pack
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), plus the Kweebec Nightmares chain (only appears when Kweebec Nightmare is installed), three dailies, and the Night Owl ladder awarding the Nightwarden set.
Requires: MMO Skill Tree 1.6.0+
MMO Skill Mastery Pack
The mastery and currency systems: 30 spendable mastery progression tracks spanning skills, individual abilities, and seven damage-school tracks (Fire, Ice, Lightning, Water, Arcane, Void, Poison), the mastery-point and life-essence currencies, and matching quests/achievements. The pack also places the Mastery Trainer, the character in the Forgotten Temple you talk to for the mastery quests and menu. The Mastery and Currency menu tabs stay hidden without it.
Requires: MMO Skill Tree 1.6.0+ (functionally needed for the full mastery feature set)
MMO Skill Taming 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 1.6.0+, plus Alec's Animal Husbandry for the Taming skill to activate
MMO Skill Stations Pack
Interactive work stations. Ships Timber Rights, a hub quest that awards a Sawmill: press use to saw logs into planks in a third-person work loop, earning passive Woodcutting and Crafting XP, scaled by your tool, with luck-tiered bonus loot. Carries the station content, the in-world block, and the loop's flavor assets.
Requires: MMO Skill Tree 1.6.0+ AND the RPG Stations companion mod (both hard dependencies); stations stay dormant without both
MMO Skill Capes Pack
A pure cosmetic asset pack: the same 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)
Never install both cape sources
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
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. Scaled enemies can cast signature moves from the shared ability catalog, and a bonus drop's odds can weigh a mob's rarity, affixes, difficulty, and region power. Reads player power only through the mod's frozen public API, never recalculating it independently. 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+ (its ability casting needs 1.6.0), ZiggfreedCommon 2.0.0+ (both hard dependencies)
RPG Stations
The interactive work-station engine, as its own mod: a diegetic third-person work loop at a station block, with tool gates, conditional loot, and a fourth-party authoring surface a pack can extend. Completely independent of MMO Skill Tree - it ships a working Sawmill and needs no progression at all. When MMO Skill Tree is also installed, the loop feeds skill XP, luck and mastery through a soft bridge; neither mod hard-depends on the other.
Requires: ZiggfreedCommon (required). MMO Skill Tree is optional. The MMO Skill Stations Pack supplies the MMO-facing station content
The stations release starts small
Kweebec Nightmare
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 (pinned to 2.0.1+), and for either standalone companion mod above. - 2
Install the MMO Skill Tree jar
The base plugin. - 3
Install RPG Stations, if you want work stations
It is its own jar, not a pack, and it goes in before the Stations Pack that supplies the content. Skip both if you do not want stations. - 4
Install the content packs you want
Any order among themselves; each is independently optional and additive. The Stations Pack needs RPG Stations from the previous step. Skip the Capes Pack if the base plugin is already installed. - 5
Optionally install the other companion mods
Kweebec Nightmare needs Perfect Utils and ZiggfreedCommon. MMO Mob Scaling needs MMO Skill Tree 1.5.0+ and ZiggfreedCommon 2.0.1+.
All of the above target the same Hytale server range as the base mod (>=0.6.0-pre.13 <0.7.0, Hytale Update 6 (0.6.x)).
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, and Building the zip for the packaging step.
