@Mitzui There are 4 main mpq for Wacraft3 (there are few additional for titles only):
- War3.mpq
- War3x.mpq
- War3xLocal.mpq
- War3Patch.mpq
The last one holds data for patch in which 3 new neutral heroes were added: Tinker, Flame Lord and Alchemist.
Within Units\Creeps\HeroFlameLord\ you will find all sound files refering to hero plus: hero model, hero portrait model and cutom clouds8x8 texture.
His summon, Lava Spawn in within similar directory: Units\Creeps\LavaSpawn.
