As a mage I want to see the difference between icons of pet nova (Freeze) and my own one. Both spells uses same icon, so I decided to link Freeze to other existing one (by editing Spell.dbc) and redraw it.
Redrawing gone well, but editing spell.dbc causes wow to crash.
What did I do (russian client):
1. Remove anything from data/cache/ruRU/
2. Run a game to let it create patch-ruRU-*.mpq files there, in my case there's 3 of them, larger than 1kb: patch...13164, ...13329 and ...13287.
3. In ...13164 containing ICONS folder I put redrawn icon of hawkstrider mount, and it worked (for hawkstrider mount). This MPQ contains Spell.dbc as well, but changing it gives nothing.
4. ...13329 also contains Spell.dbc, and with it changed there's WoW Error appears immediately after launch, telling that "An attempt was made to move the file pointer before the beginning of the file." File is BDFilesClient\Spell.dbc. DBC and MPQ (Ladik's) editors are safe.
5. ...13287 just cannot be opened.
Would be nice to finally get a resolve.
