If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.

* Tinker rarely finds himself in the middle of a fight, which is where Chaos Knight typically thrives, and even in the rare cases of being so, at level 3 Tinker's constant rearm and blink away can kite and dodge Chaos Knight's spells reliably, so Chaos Knight has very little catch against Tinker's mobility. This gives Tinker impunity to create more chaos in a teamfight than Chaos Knight can control, laying down the field with March of the Machines and constantly being hit by rockets and lasers.

* Impetus deals double damage to illusions, making it effective against Phantasm.

* Time Walk and Backtrack allows Faceless Void to easily negate Queen of Pain's burst damage.
* Chronosphere prevents Queen of Pain from escaping with Blink, and her low survivability makes her an easy kill.
* Time Dilation will prevent Queen of Pain from using her low-cooldown spells or force her to buy Black King Bar or a Eul's Scepter of Divinity to dispel the debuff and re-engage.
