Head-to-head Dota 2 7.41e win rate from ranked matches.

Relying on Magnetic Field to save you from Chaos Knight is a common mistake. His whole kit is built to isolate and delete a single hero, and Arc Warden is a prime target. Chaos Knight uses Reality Rift to get on top of Arc instantly, making kiting with Flux difficult. Phantasm then creates a situation Arc Warden can't handle; his single-target focus is terrible against multiple strong illusions that will run him down. Even inside the Field, a well-timed Chaos Bolt can lock him down long enough for the illusions to finish the job. The Tempest Double also becomes a liability, offering up a huge gold bounty when caught and killed.
