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.

He is recommended for new and intermediate players.

Recommended Items
Manta Style is an excellent item as it will improve your illusions by providing stats and works with Reality Rift. Chaos Knight has one of the highest starting movement speeds in the game, bested only by Luna. By giving him Drum of Endurance and Manta Style he can effectively chase down his opponents. Getting predominantly strength based items late-game is a good idea to ensure that his illusions get the extra damage.
