Scourgerot by sabers

Basic attacks slightly lower enemy resistances for a brief duration, increasing their damage taken. Stacks up to 5 times and is refreshed with each basic attack.

Scourgerot fires his arm forward in a straight line, damaging all enemies in its path and applying a stack of Plagued Wounds. Each subsequent enemy or minion hit after the first takes less damage. The furthest enemy struck is also stunned for 0.5 seconds.

Scourgerot wraps his arm around himself for a short while, slowing his movement speed and losing the ability to attack or cast spells. However, he gains a small aura of pestilence that stacks Plagued Wounds on all enemy heroes remaining in its area of effect, giving him a shield that gains strength depending on the number of heroes affected.

Scourgerot plows his hand into a target location, infesting it with a blight that grants an increasing slow effect in an area for a moderate amount of time. Enemy heroes who linger for too long in the blight will be rooted for a brief duration.

Scourgerot plunges his arm into the ground before allowing it to burst out of the earth after a brief delay and knock up enemies at the target location. Not moving after the knock-up effect will cause his arm to start channeling deadly toxins into the air in a slowly increasing radius for a short time, severely poisoning anyone caught in its area of effect. Moving, being displaced, or being incapacitated will cancel the effect.

Scourgerot drinks a deadly concoction of toxins that temporarily grants his other arm the same powers of pestilence. Scourgerot gains attack speed while Toxic Rush is in effect, and the effects of Plagued Wounds, Diseased Shield, and Blighted Earth are doubled. Black Reach and Putrid Grasp may also be used again for free for a short time after the initial cast.

Instead of mounting, Scourgerot shoots his long, plague-infested arm into the ground, grasping firmly before vaulting himself to a target location.
