This version of Support Chrono is a boon support that provides 100% Quickness Quickness and Alacrity Alacrity uptime for its party. This massively increases the group's damage and healing output due to faster cast times and lower cooldowns. In addition, it can increase group wide boon uptime through , and cheese certain raid mechanics using , , and .

This iteration of Support Chrono has been largely superseded by other sources of Alacrity Alacrity. A higher-DPS version that provides only Quickness Quickness is now the common choice, which can be found here: Chronomancer - Power Boon Support.

This build is more pug-friendly as it doesn't require your group to stack within 240 units of you for , and it assists players outside your subgroup with 10-target . also means that you generate twice as much Protection Protection for your subgroup with .

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.

Remember to get a sword, focus, and shield offhand.

Standard Variant

The suggested gear here provides you with enough boon duration (65%) to comfortable sustain boons on your group, without trading off too much damage.

The following gear assumes you're not able to use any Infusions to gain extra concentration. If you can use infusions, you can use dT's gear optimizer to decide what combination of gear will be best for you to use.

If you're running with a group from LFG where you can't be sure of player skill, or with a generally inexperienced group you may want to run 100% boon duration to ensure boons stay up even with things being less than ideal. In those suggestions, the following gear setup is suggested:

Tanking and Toughness

If you're the tank in an encounter with toughness-based aggro, you will need to add toughness so that you have the highest toughness in your squad. Do a toughness check before pulling the boss and adjust your gear accordingly.

Here are some important toughness thresholds that you may need to take into account when gearing:

  • 1000: the baseline toughness of all builds
  • 1150: Soulbeasts with
If you only need a small amount of toughness, you can add one toughness infusion, replace one ring with Knight's stats, or use /. If someone has an absurd amount of toughness consider running Chronomancer - Minstrels Tank or similar.

Other Variants

  • can be put on your shield for significantly better CC from (as long as you stay on your shield while the projectile is active). It should also be put on your pistol if you're running one.
  • can be used if your group doesn't need the fury from Pack Runes. Note that if you're running scholar runes you'll likely want to pick up extra boon duration from your gear as you lose 15% swapping from Pack to Scholar.

  • if you don't need extra boon duration.



The main role of Support Chronomancer is to provide permanent Quickness Quickness and Alacrity Alacrity to your group. You can provide these boons directly with the following skills:

The final part of Chronomancer's boon-sharing arsenal is , which extends the duration of boons that have been previously applied to whomever it hits (it will not apply boons that the player didn't already have). This is used to bridge the gap between boon applications from your other skills, and if you're using it will affect all 10 players in your squad. In some cases you may need to copy for extra boons.

When all your boon sharing skills are on cooldown, just deal DPS with , phantasms, and autoattack chains until your skills are available again.

General Tips

  • Coordinate with other boon support classes in your group (most likely another chrono or a renegade/firebrand pair) to ensure there aren't any gaps in boon coverage - remember that if traited your will affect everyone in the squad!
  • Remember to press to proc , as well as for the extra free damage.
  • Proper well placement is crucial for boon uptime. Make sure you throw your wells where your teammates will be standing, not under your own feet. As a general rule of thumb, you should throw wells at the back of the boss, as this is where the DPS are usually stacking in melee range.
  • and only provide boons when they expire, 3 seconds after the initial cast. Make sure to keep this in mind if your squad is moving around during the fight.
    • This is especially important to keep in mind when starting a fight or a new phase after boons have expired - don't waste your before boons have been applied to people!
  • When possible you should use to increase your boon uptime. See "Continuum Split" below.
  • You can delay if you need to Aegis Aegis a specific mechanic. This may cause you to briefly drop boons, but it's better than wiping because you didn't do your job.

  • Another use of is to get a shorter cooldown on and . Because these skills have a longer cooldown than , you should only cast these skills inside if possible. This effectively reduces their cooldown to the cooldown of .
    • On fights where CC is important, like Samarog, you should always save to cast rather than boon-sharing.
  • Always activate as late as possible in the cast animation of whatever skill you want to . This is because skills only go on cooldown when their cast animation ends, allowing you to fit more skills inside your .
  • If you use as your final skill then immediately cast it again upon exiting , you can catch both walls as they return and reduce the cooldown by 20 seconds instead of 10.

Currently not a great pick as alacrity renegades (both power and 2x condi RR) are ubiquitous and having to provide alacrity leads to a huge dps and utility loss. Offensive StM-based 5-man quickness Chronomancer builds are superior in just about in way these days, so this is only a reasonable pick in case you have trouble finding a renegade for your alacrity needs.

Screaming gave this build 5 stars April 2019

Still mandatory, always, and still by far the best option for casual and meta clears alike. No alternatives come even close to the utility of a Chrono-based composition, nor the reliability of chronomancer's boons. Nerf it, and you just take more chronomancers.

Chrono is no longer the meta-defining monster it used to be but is still an immensely powerful boon support in raids. Deals high personal DPS and has a ton of useful utility too.

Rotation and build may have changed but the demand for Chronomancers will remain until Quickness and Alacrity are deleted from the game. The rotation is less forgiving than pre-patch but still offers strong boon coverage that are key staples in any composition.
