DotA2 Arc Warden Skill Build Guide

Dota2 Arc WardenDotA2 Arc Warden (Zet): In the magnetic and ether touched lands of the far south a perpetual storm rages. In this strange, barren land, only an isolated tribe of nomads know to exist. These nomads worship the very nether storms that plague the land, and born out of this bizarre energy and intense faith, a chaotic god emerges. Sensing the calamity of the approaching battle of the ancients, the infant deity imbues his most trusted prophet with avataric powers and sends him to quell the forces of order and good that impede his growth. Wielding the ether touched powers of lightning, magnetism, and the ability to reverberate an exact duplicate of himself into being, Arc Warden is a force to be reckoned with.
