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 or Mirage that provides alacrity. If for some reason you don't have another player providing alacrity, you should use Chronomancer - Utility Boon Support instead.

Slot Changes


If you need a utility skill you can swap out :
  • 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.


  • 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.




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 most 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.

Opening/Continuum Split Burst

  1. - only if you have it slotted.
  2. Weapon swap Weapon swap
  3. - enter during the cast of this skill.
  4. , , - Shatters have no cast time so these can just be mashed, but make sure you press them in the order listed.
  5. - You won't be able to cast this if you entered Continuum Split with 2 clones.
  6. if it hasn't ended already

General Rotation

  • Outside of the opening burst and your rotation is simply casting skills off cooldown and swapping weapons to maximise casts of and . If multiple skills are available at once, use the following list to prioritize the order you cast them in:
  • 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, .
  • If you're using Focus, simply replace with

Continuum Split

  • Your should come off cooldown while you're on your shield set. When you swap to shield and is nearly off cooldown, avoid casting skills other than and . When your weapon swap is ready, move to step 5 of the opening burst.
  • Your first will be shorter than the rest since you will only be able to generate 2 clones before entering it. As a result it won't be possible to complete the full rotation listed before it ends.
    • As a result, should be skipped in your first Continuum Split.
    • If you're still struggling to fit everything in, consider skipping the and and simply casting instead.


  • You can use to pull adds onto the boss if needed.
  • 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, 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.
  • If your opening is ending before you have a chance to cast your shatters, try moving them up a few steps earlier and don't be afraid to cast them during other skills.

STM / Power Boon chrono is an absurdly fun and effective build that can manage extremely high DPS even as a support. This build should be a staple of any chrono main's arsenal.
