Skyriding / Dragonriding for TrinityCore Master (Retail 12.x)

The first known working implementation of Skyriding (Advanced Flying / Dragonriding) for TrinityCore master branch (retail).

As of March 2026, the official TrinityCore PR #30199 by Traesh has been unmerged since August 2024. This patch builds on that work and adds the critical missing piece: the Vigor aura (372773), which is required by the WoW client's DB2 spell data to allow active Skyriding abilities.

What This Enables

• Skyriding: Momentum-based flight (diving, climbing, physics-based movement)
• Steady Flight: Traditional static flying (hover, constant speed)
• Flight Style Toggle: In-game button to switch between Skyriding and Steady Flight
• Active Abilities: Skyward Ascent (Lift Off), Surge Forward, Whirling Surge
• Auto-learning: All abilities automatically taught on login (Level 10+)
• Flying everywhere: Bypasses incomplete AreaMountFlags in DB2

Quick Start

Tested on: TrinityCore master, WoW 12.0.1 Build 66337

1. Apply the C++ patch

cd /path/to/trinitycore-source
git apply skyriding_trinitycore.patch

2. Copy the spell script

cp spell_advanced_flying.cpp src/server/scripts/Spells/

3. Reconfigure CMake and compile

cd /path/to/build
cmake /path/to/trinitycore -DCMAKE_INSTALL_PREFIX=/path/to/server -DTOOLS=0 -DSCRIPTS=static
make -j$(nproc) worldserver

4. Apply SQL (on your world + characters database)

mysql -u user -p world < skyriding_sql.sql

5. Deploy and restart

cp build/bin/worldserver /path/to/server/bin/worldserver
# restart worldserver

Why It Didn't Work Before (The Key Discovery)

The WoW client's DB2 data (SpellAuraRestrictions) requires CasterAuraSpell = 372773 (Vigor/Dragonrider Energy) for the active Skyriding abilities:

Spell	Name	Requires Vigor
372608	Surge Forward	Yes
372610	Skyward Ascent	Yes
361584	Whirling Surge	Yes

Without the Vigor aura on the player, the WoW client itself blocks the cast and shows "Not yet learned" - no packet ever reaches the server. This is why previous implementations (including PR #30199) couldn't get the active abilities working.

The fix: Cast spell 372773 on the player when Skyriding mode is active. This satisfies the client-side CasterAuraSpell check and allows the abilities to fire.
