Timbersaw

Rizzrak the Timbersaw is a melee Strength hero that excels in dealing pure damage and causing destruction around the battle field. He is a strong ganker whose spells are low in mana cost, cooldown and can destroy trees in an area around him, as well as inflicting pure damage; this makes him an good counter to magic tanks and high armored heroes. Whirling Death unleashes razor sharp edges that deals magical damage to an area around him and reducing the primary attribute of his enemy hero; if Whirling Death cuts down trees in the process, the damage type becomes pure. Timber Chain allows him to latch himself to a tree, pulling him towards it and dealing pure damage to enemies in his path; the low cooldown and low cost of this ability greatly increases his mobility. Reactive Armor makes him more resistant and resilient, increasing his armor and health regeneration temporarily every time he gets hit by an enemy, stacking up to a maximum level. His ultimate skill, Chakram fires a spinning saw blade at a targeted location, cutting down trees and enemies in its path, dealing AoE pure damage, and slowing his enemies for every 5% health they are missing.
