Justification / Modifications:
Escape, Nuke and Chase in one ability. Time Leap is superb and has to be maxed first. The first level of rewind gives you +10% chance to backtrack while each following level only gives 5%. Therefore we get that first level asap. Its much better than stats.
After that Curse of Ages is maxxed to increase your Lane presence.

Starting Items:
Runes of Blight, Healing Potion, Logger's Hatchet, 3x Minor Totem

Core:
(Iron Shield >>) Lifetube >> Steamboots >> Runed Axe >> Elder Parasite

Runed Axe is a very good staple item for Chronos. To get the most out of it build it asap. Get an Iron Shield if the lane is hard and you most likely also want an early Lifetube. Then build Steamboots and finish Runed Axe. If you have 3 or more hard carries on your team I strongly suggest you skip runed axe and go straight for Elder Parasite (because you will not have enough lanes/forest to farm with so many carries thus making Runed Axe a lot less effective).
Also core (altough arguably) is Elder Parasite, giving you the very effective attack speed to steal agility and bash under Chronofield. Some prefer to get Elder Parasite before Runed Axe; I usually don't.

After Core:
Geometer's Bane >> Savage Mace >> Riftshards (>> Shrunken Head)

Geometer's adds much needed survivability to this build.. If you see yourself dying too early in fights get a Shrunken Head earlier or go for a Behemoth's Heart. Shrunken is very situational (more so than on other heroes). Usually you can eliminate the main threat in your chrono field. Should you still get CCd/Nuked to fast after Chrono field you can consider Shrunken.

Alternative Items:
Charged Hammer: Attackspeed and damage. A popular choice, especially in pubs.

30-Seconds-Guide
- This hero needs a lot of farm, and he is not very good at it. After the laning phase go to the lane pushed the least and ask your teammates to leave so you can "static farm" (farming while counter-pushing the lane to stay safe).
- Try to place the Chronofield to trap your enemies right at the edge of the sphere. This way your melee allies can still attack them.
- Always carry a Homecoming Stone when farming so you can Time Leap into the forest and TP out when you get ganked.

Counters:
- One Word: Barbed Armor. Chronos will instagib himself when he attacks you into Barbed Armor when he has Elder Parasite on.
- Don't let him free-farm. It's not easy to gank him due to time leap but try to not let him solo farm a lane. Scaring him away is enough. A few coordinated ganks during the mid game will significantly hurt him.
