Change Permanently

Well, sorry if this has been posted before, I'm relatively new to this, but, I've spent a couple of hours searching but to no avail, as such I'm actually posting this. I need help where I can change the skin of a model to something else in all games, as in the core files. Well I did come across one thread, it said it needed MPQMaster, but I don't know how to use it. Is there any tutorial here, can somebody point me to it or just a brief information. For example, every game I play the 'Anti-mage' char skin is changed to the skin I downloaded or something.

Use some MPQ program to open War3.mpq and then find the demon hunter skin. Replace the file in the MPQ with your custom skin (keeping the same path).

Disclaimer: Playing on B-Net with a modified MPQ is against the ToS, so...

You can broke your mpq in this way and unable to patch or play multyplayer games.

There is no need of mpq editing, if you allowed local files, you can place file directly to war3 folder.

You can always create backups.

Ah, but playing with different skins WOULD be cool, no doubt about it.

If you care about your CD-key, do not edit your MPQs. There is no guarentee you won't get banned, and it's highly likely if you try and play ladder / b.net that you WILL get banned.
