Chaos Knight

Chaos Knight is a melee strength Hero famous for his unorthodox disables and is most commonly played as a semi-carry and ganker. His core abilities all have effects that are based on randomness: Reality Rift, for example, pulls Chaos Knight and his target to a randomly chosen point along the line between the two at the time of casting. The random factor of these abilities mean that they can be extremely powerful if the random number generator is in your favor. This is especially true for Chaos Bolt, which at max rank has a chance to be a 4 second targeted stun, which in turn is almost a guaranteed kill early in the game (4 seconds is equivalent to Black Hole). This ability makes Chaos Knight into a very strong roamer in the early-mid game. At the same time, Chaos Knight's Chaos Strike and Phantasm abilities both scale well with items, giving the Chaos Knight presence even in the late stages of the game.

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're 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, and you won't 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'll 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 grants you better stats, too.
 * An Armlet of Mordiggan paired with a Helm of the Dominator/Satanic can make a very powerful combination, especially with attack speed and damage items.

Trivia

 * Chaos Strike's skill icon bears a similar appearance to a D20 dice, commonly used in table-top RPG games, where a full 20 usually results in a critical. This is representative of the chance that comes with the skill.
 * Chaos Knight's lore and dialogue lines draw many references to the Four Horsemen of the Apocalypse.
