Chronomancer - Boon Support Healer
This is a rough draft. Once adequately written, it will progress to the testing stage, where it can be rated by the community. You can help by proposing changes with a comment.
Focused on: Support and Utility
Designed for: Raids

Overview
Due to the incredible range of utility and active defense that Chrono can bring, it remains a good choice of tank and boon support in raids.
However, many players will lean so hard into the defensive/utility aspects that they end up dealing no damage. If you find yourself DPS-racing a healmech, you might as well be a healer yourself!
Due to the difficulty providing key defensive boons such as 
Regeneration and 
Protection, this build may struggle to be a solo healer on some encounters but is a great choice for secondary healer.
Chronomancer provides EITHER 100% 
Quickness uptime or 100% 
Alacrity uptime as well as 
Fury and 25 
Might. Both variants can dedicate multiple slots for utility skills, though the Quickness is slightly more flexible as its boons come from shatters rather than wells. On the other hand, Alacrity Chronomancer is one of the few builds that can provide its key boons at long-range, making it an excellent choice on encounters that require it to be a long way from the stack.
Due to the sheer range of options available, there is no "default" build for heal chrono, but rather a framework into which you can slot what you want for each encounter.
Skill Bar
Weapon Variants
Sceptre/Shield Should be considered mandatory, but the other set can be what you like:
- Greatsword (coupled with the Domination traitline) provides some burst healing and boon rip.
- Staff can provide similar burst healing to Greatsword without the need to trait into Domination. It can also be used to improve personal Regeneration uptime and provide some random extra boons via . Be aware that you should often NOT use if tanking as you want the boss to remain still rather than chase you.
- Offhand Focus can be taken if you need to pull adds into the boss.
Skill Variants
Healing
- is a massive group heal that can be boosted even further if using .
- provides more consistent healing, as well as being able to trigger frequently. Crucially, as the charges are instant cast it can be used to provide an AoE condi cleanse to counter
Fear or 
Taunt. - doesn't provide any group healing, but does offer a short projectile reflect, and if running Chaos with it can also be used to provide AoE
Aegis. - (Sylvari only) is the only way you have to reliable provide Regeneration to allies, which will be very helpful if you're the only healer.
Utility
provides ~12 average Might to your subgroup. Combined with , this is sufficient to provide over 20 average Might. is taken as standard to fill in any gaps, but can be swapped out if you have other sources of Might in the group.
Quickness variant: Only shatters are needed for Quickness so you can bring any utility skills you need.
Alacrity variant: You need 2 wells (other than ) to maintain Alacrity, otherwise you can bring whatever you need.
- CC options:
- does decent CC and also removes boons.
- is not as strong as but recharges on a much shorter cooldown, which may make it better on encounters that require very frequent CC. When charging the mantra, it also reduces the cooldown on .
- has a long cooldown, but is instant cast and could be taken along with the above if you really want to go overboard on CC.
- Aegis:
- if running Chaos with - short cooldown and instant cast, but be aware that the Aegis triggers at the location you activate the skill, not where you end up.
- can be used less frequently, but the duration of the Aegis is longer, which may be useful if you have concerns about your timing.
- If running , any signet will also provide Aegis.
- if running Chaos with - short cooldown and instant cast, but be aware that the
- provides a long-duration reflect.
- provides Stability to your group.
- if you need a portal.
- allows you to get a second use out of a key skill if you'll need it more often than the cooldown. Often used together with .
Elite
- 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.
- should be used if an encounter requires heavy CC, and it can also be used to pad Alacrity if running that variant.
- bigger and faster CC than but on a longer cooldown, which may be more suitable for some encounters.
Template Code
Note: Due to the aforementioned variety, these codes are incomplete. In particular the grandmaster trait in Chronomancer has not been selected.

Specializations
Quickness variant: Use .
Alacrity variant: Use .
Trait Variants
- can be taken if running Focus and the reflect will be valuable.
- gives you greater access to Distortion and Aegis, but you lose your main source of healing.
- If taking this, you can constantly spam to trigger as your sustained healing instead.
- - if not bringing any wells, you can slightly increase your CC with this.
Specialization Variants
Chaos
Chaos offers more personal survivability, higher boon duration, and perhaps most usefully .
- You could bring to give yourself more
Stability.
Domination
With Greatsword has the highest illusion generation of any weapon and so can be used to rapidly trigger for burst healing on demand. You should be able to trigger this trait 11 times in a single weapon swap.
Equipment
Any combination of 
Minstrel stats or 
Harrier stats (or even 
Giver stats) will provide more than enough concentration to maintain boons. The setup below is merely a suggestion.

Utility
Usage
As a healer, you don't really have a fixed rotation beyond using certain skills off cooldown, but consider the following guidelines.
Quickness
Quickness provision comes from and so frequent clone generation and shattering is key. Open with your offset phantasm, then for some opening clones for . Within CS spam shatters and use , and/or to give yourself a large buffer of Quickness.
Outside of CS, autoattack on sceptre to generate clones and use and as soon as you have three clones.
Use and off cooldown for Might and Quickness.
If you have , you can use it should you notice Quickness dropping.
Alacrity
Thanks to , and all your wells generate Alacrity. Open in much the same way as the quickness variant.
Outside of CS, autoattack on sceptre for healing and use your chosen wells off cooldown.
Greatsword Burst
If using a Greatsword and Domination, you can spam illusions to trigger using a rotation very similar to the DPS one:
Weapon Swap- Autoattack and use when it comes off cooldown
- Weapon Swap
Healing
You have two options for sustained healing:
- heals in an AoE every time an illusion is generated. Phantasms will trigger this trait twice (once when they appear, and again then they become clones).
- provides a moderate AoE heal every time you charge a mantra. has practically no cooldown after its charges are expended so you can spam it constantly for healing.
Both of these options provide roughly equivalent healing per second, and due to the downtime on from having to expend charges, you can get in a full auto chain on sceptre. However, having to constantly activate will be quite awkward and the Quickness build needs consistent clone generation, so relying on sceptre autos is better in practise, leaving uncharged in case extra healing or Might is required.
If playing with , you will have regular healing from your wells. If you don't need it for Alacrity, you can save for an emergency as it has an inherent heal on the final pulse as well as triggering the trait.
Tanking
You have many options to deal with incoming damage. Aside from your inherent healing you have the following:
- - a two second channeled that blocks an attack and causes you to evade afterwards. Also generates two clones so you are immediately healed via . The cooldown is very short so you can use it liberally even if you're not tanking.
- - A lengthy channeled block that will provide AoE Protection after use, as well as triggering twice from the phantasm. If you block an attack, it flips to for 10 seconds, allowing you to repeat the skill.
- - Up to four seconds of invulnerability with three clones, allowing you to completely ignore the majority of attacks. Activating it also provides Aegis in an AoE.
- - three pulses of Aegis in an AoE and personal Stability, which is enough to prevent a lot of incoming damage.
Continuum Split
Aside from providing an opening buffer of boons, you can use to get extra uses out of skills, either for the utility or for healing.
Crowd Control
Always have:
- -
Daze. Even on the Quickness build you shouldn't need to use this for boons, and so can save it for CC. - -
Stun
On off-set:
