Dota 2 river mods
The river is the strip everyone stares at all game. Valve sells these as vials; these are the community versions and they layer over whatever you own.
The D2PFX catalog has 20 mods in this category. Each changes what you see on your own screen; everyone else sees their own game.

Installing any of these
Open Dota 2 Mod Manager, find the hero, press Install. The app puts the file in a free pak slot in the folder your game mounts, tells you when two mods carry the same file, and puts everything back after a Dota patch. The full guide, or the manual route if you would rather do it yourself.
