This iteration of Support Chrono is a boon support that provides 100% Quickness Quickness uptime for its party while dealing high personal DPS. This massively increases the group's damage output due to faster cast times. In addition, it can cheese certain raid mechanics using , , and .
This iteration of Support Chrono is currently the most commonly used option and is paired with a Renegade that provides alacrity. If for some reason you don't have a renegade providing alacrity, you should use Chronomancer - Utility Boon Support instead.

Slot Changes


If you need a utility skill you can swap out and/or :
  • helps with reflects.
  • provides aegis to your subgroup, useful for fights like Deimos CM.
  • provides Stability to your group.
  • for encounters that require heavy CC, and for recharging Time Sink.
  • If you're using a Focus, you should also use to make up for the loss of clone generation.


  • should be used if an encounter requires heavy CC.
  • is not required to maintain quickness, but it provides an easy way to start fights with quickness and can be used to cover up any mistakes in the rotation.



  • if you're using a focus offhand.


There are many variations of gear for Chronomancer and some of them can be difficult to acquire, however they all share a common goal in their stat choices which is to reach enough boon duration to maintain sufficient boons for their group. The required boon duration will depend on the skill of you and your group, as well as whether you're running with builds such as Firebrand - Quickness Support Power DPS and Renegade - Boon Support Power DPS. The version listed here will in theory work for all fights but if you find that your quickness uptime has gaps, don't be afraid to replace Berserker equipment with Diviner gear for additional boon generation.

Higher DPS:

You can use these if you're confident in your ability to maintain quickness on your party. Note that these shouldn't be used with the Focus variant due to its inherently lower quickness generation.


This build generates all of its quickness through shatters thanks to , therefore it is important to maximize value from each shatter cast but you should also make sure not to waste clones by summoning extras and overriding an existing one.

  2. Weapon swap Weapon swap

  5. Weapon swap Weapon swap

General Tips

  • Fill gaps in between skills listed in the rotation with auto-attack chains.
  • Make sure not to interrupt your autoattack chain as the damage from it is heavily loaded into the final strike, .
  • You can use to pull adds onto the boss if needed.
  • should be cast as soon as there is a charge available, but make sure to only use the last charge if you know there will be a period where you can't hit the boss in the immediate future where casting the long preparation channel won't cost you any DPS.
  • should be cast as soon as it comes off cooldown, once the opening burst is completed.
  • As previously mentioned, is not necessary to maintain quickness and is taken to provide a quick source of quickness at the start of the fight. After this, it can be cast at any point to cover any quickness gaps that may occur due to fight mechanics or player error.
  • and can be used to avoid incoming damage with less of a DPS loss than dodging.

Clone Sources

  • Each of your Phantasm skills will create a clone after a short delay, once the phantasm has completed its attack. Keeping track of your phantasms is important to ensure you don't waste any clones.
  • creates a clone on your target.
  • creates a clone on your target.
  • If you're using it, creates two clones on your target.
  • creates a clone on your target, but only if you take damage to trigger the counter.

Shatter Usage

  • is your primary shatter and does by far the most damage - if you have multiple shatters available this should be your first pick. It's ok to delay this a little bit if you're only at 2 clones.
  • should only be cast when you're at 3 clones, but make sure you'll have enough clones for the next afterwards.
  • should be saved for emergencies to provide CC or cover quickness gaps.
