Chaos Knight

Chaos Knight is a melee strength Hero with one of the highest physical damage outputs of all heroes. He is mostly played as a semi-carry and ganker. As his name implies, he has a theme based on randomness and uncertainty. His regular attack has an incredibly wide thirty damage spread, making his last hitting ability somewhat unreliable. Chaos Bolt is his most notorious luck-based ability which, at max level, can stun a target anywhere between a mediocre 2 seconds to an effective 4 seconds that will almost certainly assure the target's death; it will also deal a variable amount of damage ranging from miniscule to moderate. Reality Rift pulls Chaos Knight and his target to a randomly chosen point along the line between the two and gives him bonus damage for one attack. Chaos Strike is a crit-based ability with one of the lowest proc chances, yet also one of the highest multipliers. The illusions produced by his ultimate, which retain his full damage and only take double damage, benefit from his Chaos Strike and can teleport alongside him to attack the target whenever he uses Reality Rift. With up to four illusions being produced at Phantasm's highest level, Chaos Knight's damage output can be multiplied to be five times as great during teamfights later in the game, and it is not uncommon to see enemy heroes being killed instantly after being Reality Rifted by the apocalyptic horsemen. Thus, Chaos Knight is played as a carry who excels in both the mid and late game, if the game drags on long enough and he is able to acquire enough strength-based and survivability items to ensure that his illusions can stay alive, he will be able to overpower most hard carries.

Tips

 * While ganking in the early-mid game, use Reality Rift to get close to the enemy, then hit him once with your bonus damage and use Chaos Bolt to stun. If you are lucky, you could even get more than 2 hits while he's stunned.
 * In most situations, max Chaos Bolt and Reality Rift first, since the critical damage from your Chaos Strike is negligible in the early game (except the armor reduction), and you will not have enough mana to summon the Phantasm(s) with your ultimate.
 * Always activate your Armlet of Mordiggian before using your ultimate, since the illusions also gain bonuses from it.
 * By buying a Sange & Yasha, you will be able to disassemble it later and build a Heaven's Halberd and a Manta Style. You may buy the first item if you need more survivability, since it gives you more health, some evasion and a reliable disarm; buy Manta Style first if you farmed really well, and you wish to confuse your enemies even more. It also grants additional increases to attributes.
 * Diffusal Blade will give Chaos Knight's illusions Manabreak. Like Phantom Lancer, an army of Chaos Knights can deplete enemy's mana very quickly. Its active ability can also be used to ensure that enemies do not escape Chaos Knight's army after Reality Rift, if Chaos Bolt is unavailable.
 * Buying an early Soul Ring will solve most of Chaos Knight's mana problems.
 * Phantasm boasts the most powerful illusions in the game, creating an army that can boost Chaos Knight's damage output for up to 400%. When used in conjunction with Reality Rift and Chaos Bolt it is often possible to destroy the target before they get a chance for retaliation. Given that your illusions do full damage and are far more durable than illusions produced by any other hero always remember that even if your main hero dies your illusions still pose a very serious threat.
 * If you manage to farm a Manta style you gain two additional albeit somewhat weaker illusions that serve to wreck havoc among enemy ranks, Manta Style illusions much like Phantasm and rune illusions are pulled to your target with Reality Rift. You can often use this to block your target in a swarm of illusions they will not be able to escape from. The ultimate orb from Manta Style also boosts your mana pool just enough to allow you to cast illusions together with your ultimate ability.
 * It is not entirely advisable to pick Chaos Knight against an enemy Medusa owing to the fact that Medusa's Stone Gaze destroys illusions regardless of their stats and given that your illusions are produced by your ultimate ability with a rather long cool down you cannot afford to have them destroyed easily like Naga Siren, Terrorblade and Phantom Lancer who can produce illusions much more frequently.
 * You may also want to be careful against an enemy Quas Wex focused Invoker. Given Chaos Knight's dismal mana pool and intelligence gain Invoker's EMP can completely drain him of mana even in later stages of the game and without his active abilities Chaos Knight is not nearly as potent.
 * Eye of Skadi is the most cost-effective stat item in the game and give the highest DPS for him; It makes you and your illusions far stronger by giving you 25 strength and 25 agility, and with 25 intelligence it almost single-handedly fixes any mana issues Chaos Knight could have by giving nearly 600 points of raw mana and some regen. At max level, it is even possible to use Refresher Orb after Phantasm, immediately cast Phantasm again, and still have a reasonably large amount of mana to work with.
