• ️ Custom GUIs — draw menus in YAML with actions & conditions, no code
• Cross-plugin Economy — one API over Vault / ExcellentEconomy / PlayerPoints
• ️ Native Attributes & Elements — a full attribute & damage system with no AttributePlus required; add your own via yml + JS
• 7 Languages — fully translatable, just edit yml
• Custom Blocks & Bridges — ModelEngine, CustomCrops, MythicMobs, CraftEngine, MagicGem, CustomFishing…
• ️ Database · PDC · PlaceholderAPI · Diagnostics — SQLite/MySQL storage, persistent data, PAPI, one-command health check

Unified Item Sources
One reference syntax to pull items from 10+ item plugins — any sub-plugin can copy and use it directly:
Bridged: CraftEngine · MMOItems · NeigeItems · MythicMobs · ItemsAdder · Nexo · CustomFishing · MagicGem. Missing plugins are skipped — no errors.


️ Platform Toolkit
Everything your gameplay plugins (or you, the server owner) need on one base:

• Scripting — GraalJS + Groovy: GUI conditions, click actions, diagnostics, external item modules
• Custom GUI — YAML-defined menus with data sources, pagination and actions, no code
• Economy — give / take / set across Vault / EE / PlayerPoints with one action string
• Custom Blocks — unified block abstraction bridging ModelEngine / CraftEngine
• Data — SQLite / MySQL storage, PDC helpers, PlaceholderAPI bridge
• Diagnostics — /qcl status shows ecosystem health, bridges, modules and health codes at a glance

️ Native Attributes (no AttributePlus needed)
A built-in attribute & damage system — attack / crit / defense / dodge / penetration, plus an element system (fire / water / thunder… with mutual restraint). Attributes stack per source across items, classes, gems and sets.
Add your own with one yml entry + a short JS hook ( on_damage_dealt / taken / kill / tick / equip…):
