patch-O.mpq (raid-visuals) ships full-replacement copies of 9 client DBC files: AreaTrigger, CreatureModelData, CreatureSoundData, SoundEntries, Spell, SpellIcon, SpellVisual, SpellVisualEffectName, SpellVisualKit.

These were frozen from a Turtle WoW 1.18.0 snapshot. Because MPQ patches replace whole files (not merge rows), any OctoWoW client running patch-O silently loses any DBC content OctoWoW added after that snapshot was taken — since the patched table simply doesn't have those newer rows.

Concrete symptom: summoning the "Buccaneer Bubbles" companion (item 98800, a team-exclusive pet) crashed clients with an ACCESS_VIOLATION, and the companion didn't even show up in the spellbook. Root cause: its model (CreatureModelData IDs 2766/2767, BabyOctopus/BabyOctopusPurple) doesn't exist in the frozen table raid-visuals ships. Spell.dbc alone was also missing 71 spell records OctoWoW has added since the snapshot.

The fix

The dbc/ folder in this repo holds OctoWoW's current live DBC baseline for these 9 tables (extracted from OctoWoW's own client patch files), instead of the frozen Turtle WoW snapshot.

patches/ and schema/ are unchanged from upstream — none of raid-visuals' actual visual/sound logic was touched. Every boss AoE indicator, icon fix, and sound tweak (duck mute, kodo footsteps, murloc dance, etc.) still applies exactly as before; only the foundation they're layered on top of changed.

built/ contains the already-patched output (baseline + all patches applied) — these are the exact files currently shipped inside the fixed patch-O.mpq release. If you have the original wow_dbc_patcher tool, running it with --dbc-dir dbc/ against this repo's patches//schema/ should reproduce built/ exactly.

Two open questions for the dev team

This baseline will go stale again the next time OctoWoW adds content that lands in one of these 9 tables (new pets/mounts/spells especially). Worth deciding on a process to periodically re-sync dbc/ against whatever OctoWoW's client currently ships.
Two of the "live" files I initially pulled (CreatureSoundData.dbc, SpellVisualEffectName.dbc) turned out to be older/incomplete compared to even the frozen Turtle WoW snapshot (missing records the frozen version had, e.g. the duck sound entry). I don't know which OctoWoW client file is the true current authoritative source for these two tables — if someone on the dev side can point to the right one, dbc/ should be updated accordingly.
