Companion to 2026_05_09_00.sql (DBC overlay for chrclasses + srci) and
2026_05_10_01.sql (proficiency skill rows in playercreateinfo_skills).
Those two grant the SKILL (Maces, Shield, Cloth, ...) to Paragon at
character creation; this one opens the SkillLineAbility rows that
CASCADE skill -> passive spell, so when a fresh Paragon is created
AC's `Player::LearnDefaultSkill` actually grants the proficiency
passives:
Block (107), Parry (3127), Dual Wield (674), Defense, weapon Shoot,
racial Mace/Sword Specialization, ...
Without this overlay, a class-12 Paragon spawns with the right skill
rows but a near-empty spellbook past the racials and class defaults
that come from playercreateinfo_action.
How it works
------------
AC's DBCStores.cpp::LoadDBC loads each store from the on-disk .dbc
file first, then merges <table>_dbc world-DB rows on top. Our patched
client SkillLineAbility.dbc (in patch-enUS-4.MPQ) OR's the class-12
bit (0x800) into ClassMask on 3,314 rows -- the same rows the server
needs for the cascade to fire on Paragon. Stock Docker installs use
the upstream `ac-wotlk-client-data` image which fills data/dbc/ from
a vanilla 3.3.5a extract, so without this SQL overlay the server
runs against an unmodified SkillLineAbility.dbc and the cascade
never fires.
Generation
----------
Auto-generated end-to-end by
`fractured-tooling/from-workspace-root/_gen_paragon_dbc_overlay_sql.py`,
extended in this commit to handle SkillLineAbility.dbc (14-int
WotLK layout, 56 bytes per record). The script diffs patched vs
stock by ID, keeps only rows whose stock ClassMask did NOT include
the class-12 bit but whose patched ClassMask does, and emits the
3,314 REPLACE INTO rows. Re-running with the same inputs is byte-
stable.
Verified locally
----------------
- Migration applies twice in a row at exactly 3,314 SQL overlay rows
(idempotent: DELETE WHERE ID IN (...) before INSERT).
- ac-worldserver restart logs:
>> Loaded 10219 SkillLineAbility MultiMap Data
-- the same total as stock (10,219 rows), confirming our overlay
REPLACES existing rows by ID rather than appending duplicates.
- Spot-checked spell IDs: 107 (Block, ClassMask 2115 = warrior +
paladin + dk + Paragon), 3127 (Parry, 2063), 674 (Dual Wield,
2157), 75 (Auto Shoot, 2052) all carry the 0x800 bit.
Existing characters
-------------------
The cascade fires inside Player::Create and Player::LearnDefaultSkill
at character spawn, so existing class-12 characters created before
this migration keep their broken state. Delete and re-roll, or hand-
grant the missing spells via .learn for individual existing chars.
CLIENT-PATCHES.md updated to add the third symptom ("proficiency
skills exist but passive spells don't auto-learn") and document
this migration as the fourth piece of the class-12 bootstrap.

AzerothCore
Build Status
Introduction
AzerothCore is an open-source game server application and framework designed for hosting massively multiplayer online role-playing games (MMORPGs). It is based on the popular MMORPG World of Warcraft (WoW) and seeks to recreate the gameplay experience of the original game from patch 3.3.5a.
The original code is based on MaNGOS, TrinityCore, and SunwellCore and has since then had extensive development to improve stability, in-game mechanics, and modularity to the game. AC has also grown into a community-driven project with a significant number of contributors and developers. It is written in C++ and provides a solid foundation for creating private servers that mimic the mechanics and behavior of the official WoW servers.
Philosophy
Our main goal is to create a playable game server, offering a fully working in-game experience.
Here are the main points we focus on:
-
Stability
- We make sure all changes pass the CIs before being merged into the master branch.
-
Blizzlike content
- We strive to make all in-game content to be blizzlike. Therefore we have a high standard for fixes being made.
-
Customization
- It is easy to customize your experience using modules.
-
Community driven
- AzerothCore has an active community of developers, contributors, and users who collaborate, share knowledge, and provide support through forums, Discord channels, and other communication platforms.
Modules
AzerothCore is designed to be highly modular, allowing developers to extend and customize the game to suit their preferences or create unique gameplay experiences. This flexibility enables the addition of custom features, content, and modifications.
We have a lot of modules already made by the community, many of which can be found in the Module Catalogue.
Installation
Detailed installation instructions are available here.
Contributing
AzerothCore can also serve as a learning resource for aspiring developers who want to understand how WoW servers work, how MMORPGs are structured, how game server emulators are created, or to improve their C++ and SQL knowledge.
If you want to contribute to the project, you will find a lot of resources that will guide you in our wiki.
We also recommend you read our Contributor Covenant Code of Conduct.

Authors & Contributors
The project was born in 2016 based on SunwellCore. Unfortunately, SunwellCore was published without any git history, so on git there are no credits for all the contributors before 2016.
