This is Awejake20's chronos guide. I reached as high as 4th on the leaderboard last split with him, so hopefully I know what I'm talking about. Chronos is a versatile god that can play every role except support, and is my favorite god to play. Here I will go over his skill set ad why I use the builds above.
Time Rift: This is his main damaging ability, which comes with a very short cool down but a small AOE. I level this move first, but not at level 1 because it is easier for me to clear wave at this level with his 3.
Accelerate: This ability gives chronos increased attack and movement speed over 7 seconds, which allows him to be effective at jungle and adc. Plus, activating this ability stops his passive wheel on 1 of 4 quadrants, giving chronos a different buff at each quadrant. Quad I gives increased healing, giving him great sustain and eliminating the need for major lifesteal such as Bancroft's talon or typhon's fang. Quad II gives a full mana refund on his abilities, further improving his sustain. This should be used before every wave clear to conserve mana. Quad III gives 25% increased magical power, and should be used to initiate attacks. Quad IV gives 35% increased power for basic attacks only, and should be used when attacking structures or initiating attacks when playing as ADD.
Stop Time: This move provides a line of damage that also stuns. I prefer this move to clear wave at level 1 because it hits the whole wave, but you can level this or his 1 first. An extremely useful move that can turn the tide in team fights.
Rewind: His ult returns him to his health and position 8 seconds ago, and is great for escaping, immuning out of a crowd control ult, or regaining the upper hand in a fight. I level this last, because doing so only decreases the cool down.
Chronos is weak the first couple of levels before he gets his 2. It is very important to play passively and not engage the enemy here, as his abilities do little damage and his 3 has a very high cool down. Once you get his 2, it is much easier to clear wave. Stop on quadrant II, then use his 3 on the whole wave and his 1 to finish it off. I typically buy potions to survive these first 3 levels, then you can use his passive to sustain after that.
These roles are played very similarly with chronos. You start to be able to clear wave easily, and at this point you can use his naturally high movement speed to rotate and gank. Use his 1 to poke enemy gods in between waves, or while melee gods are busy clearing wave. Use his 3 to stun enemies who are bold enough to attack you. His passive will provide sustain.
With quadrant IV of his passive, chronos can deal a great amount of basic attack damage at a high attack speed. In this role, your main focus should be initiating with quad IV instead of III, and dealing damage through auto attack instead of abilities. Don't be afraid to use them though.
The high movement speed created by his 2 makes him able to move through the jungle probably faster than anyone in the game. Here, you should use quad III in the jungle and hit enemies with the stun to initiate the tank. And if you ever run into a sticky situation, you can just ult away.
Blessing: Mages Blessing should be the main starter item, but hunters blessing should be used at adc and assassins when jungling.
Boots: I typically go purple boots for the penetration, but another option is to go blue boots for early CDR and switch them later for purple. Traveler's shoes could be good for jungling, but not necessary.
Chronos Pendant: I get this item second because chronos is much more effective with low cool downs. The cool downs are very high on his 2 and 3, and these builds still do massive damage while giving you your moves back fast.
Spear of Desolation: This is a great item that provides power, penetration, and CDR. What more could you ask for.
Polynomicon: This is a staple item on chronos. Once you get enough power in the first three items, you can add in a polynomicon proc in between all three moves in his combo, which will do hundreds of damage on top of you're already high ability damage.
Obsidian Shard: with penetration that scales with protections, this item allows you to completely shred enemy tanks and non tanks.
Demonic Grip: This replaces obsidian shard for adc. It still provides penetration, but does so in a manner more conducive to auto attack damage.
Rod of Tehuti: This item simply tops off your build with a whopping 150 magical power.
Relics: I typically go some combination of aegis, beads, or teleport. Aegis can protect you from a burst damage ult until you can ult away. Beads are useful if the enemy team has a lot of crowd controlling ults. Teleport is necessary for solo, and great for split pushing.
No matter what my role is, during the team fighting stave I operate out of the jungle more, hitting enemies with the stun, or picking off mages that stray too far from their tanks with his combo.
Chronos also has the ability, with polynomicon and quad IV, to do insane amounts of structure damage. One option instead of team fighting late game is to split push by teleporting to a ward. By utilizing quadrant IV and the polynomicon proc, I have destroyed phoenixes in less than 10 hits. Plus, you always have your ult to escape from an enemy gank.
Chronos is super fun to use, and can be played in almost any role. Please leave comments on any changes/suggestions/updates you think I should make on this guide. These builds and strategies have worked well for me, and I hope they do for you Too:)
