Boush the Tinker is a hero from Dota Allstars. He is an Intelligence Sentinel/Radiant hero.
Goblin engineering was always innovative, but Boush brought it to such extreme that most refuse to believe that his powers lie in machine and rather think that he fights with magic. He can shoot focused light and homing projectiles as powerful and as flashy as most destructive Elven Arcane spells. It is said that not even the best Necromancers can raise armies comparable to seemingly endless amount of clockwork goblins that Boush can easily summon. And while some refuse to believe in his machinery skills and other call him the master artist of engineering, none can deny the destructive force of this goblin.
Boush's rare voiceline was; "Suck my lvl1 dagon!"
