For a Gutter Runner, stealth is everything. Always moving in the shadows, the Gutter Runner wears a black cloak to blend in with the surroundings and makes as little noise as possible. Equipped with Warpstone Rat Claws that glow a sickening shade of green, the Gutter Runner will expertly leap at its enemy, using its weight and momentum to knock the player onto his or her back. Left prone and vulnerable, the Gutter Runner will then proceed to hack into the hero's torso, forcing the rest of the players to rush to the aid of their comrade.
Having undergone gruelling training in their mysterious fighting styles, the Gutter Runner is able to bend and contort its body, making it incredibly nimble and able to move at speeds unachievable by man. While attacking a hero, it will focus all of its attention in killing him or her, but once the other players start attacking it, the Gutter Runner will roll backwards and disappear into a cloud of smoke.
