Guild Wars 2

Ok, so there’s been a lot of back and forth on chrono builds lately, particularly with the boon cap. Some people have said you only need 94% and some people have said you need absolutely 100%.

I was one of the people that took someone else’s math at face value and went with 94%. However, after finally looking into this myself (thanks Molch for provoking me to do this, lol), I found that the actual boon cap to get max quickness uptime is 96%. I posted this in another thread, but for clarity’s sake and to keep that one from getting too side tracked, I started this one.

Here’s the reason for the 96%:

• Boon duration is rounded to the nearest quarter second based on the boon duration percentage from your stats. This is why the duration of Time Warp in the attached image is 1.25 seconds, when I only have 20% boon duration.
• Because of the rounding of duration, you only need enough to get to the point where duration is rounded to the highest duration possible. For low duration boons, this is a lower number and for high duration boons, this is a higher number.

Below are the boon duration caps you need for the various quickness-granting abilities:
Time Warp – 1s quickness ticks ~ 88% boon duration caps this at 2s.
Tides of Time – 1.5s quickness ~ 92% boon duration caps this at 3s.
Runes of the Chronomancer – 2s quickness ~ 94% boon duration caps this at 4s.
Well of Action – 3s quickness ~ 96% boon duration caps this at 6s.

From a practical sense, you may only need to get to a point where you need 46% duration if you can count on having a herald in your group for the 50% from Facet of Nature.

There’s two main ways to reach this cap with a minimal impact to your personal DPS:
1) Sigil of Concentration with 20% boon duration food.
2) 5x Runes of Surging with 1 Platinum Doubloon, 20% boon duration food and Bountiful Sharpening Stones.

If you want to run Runes of the Chrono with Sig of Inspiration, go with the first option.

(As a side note, for anyone that wants to model this in a spreadsheet, the MROUND function is really handy)

thanks for the info

skill facts round up. actual duration, on the other hand…

Hmm… I don’t really like the concentration sigil. It works only 70% of the duration witch might mess up the rotation a bit, especially the one with CS. It would still be possible tough, but for my taste it’s a bit too “happy world” oriented. Not so easy content or when you have to tank, wich might force you to stay longer than 10 sec on your shield or whatever will drasticly reduce the efficiency of this sigil. I wouldn’t blame anyone for using it tough, it’s good, but just not my style. You also shouldn’t ignore the fact that you’ll miss a dmg oriented sigil with it.

I like the 2nd option much more, even tough those sharpening stones are ridiculously expensive. I’ll probably just stay with my leadership equip.

^this.

I honestly do not know if it just says ,25 or if it really is ,25. It might aswell be just a tooltip thing, I didn’t do any testings on that so far. I mean there are attacks that have strange numbers like 0.84 is a common one and for conditions even small numbers count aswell, why would it be different for boons? Since quickness stacks 9 times it’s hard to tell how it works, so I’ll simply get my 100% duration. We could test it with another boon like reta or aegis tough… ;3

Anyhow – thx for sharing! I really appreciate it! ^.^

Hmm, well, it could be that the duration does round to the decimal despite the tooltip, but I’m wondering if this has been tested.

Not sure if it matters much though if you go with 1 of the two options above. If you go sigil of conc with food, then you’re a over 100% on proc. If you go surging runes with doubloon, then you’re at 99% and I don’t think that you could justify 1%, even if there isn’t a rounding behind the tooltip. =P

Yea it won’t really matter that much either way, I agree I’ll test it some day with regen.

Okay, it seems I somehow missed this thread -.-" My bad, I’ll post my findings here, too, since they fit better. Boon duration is only rounded in the tooltip. Quoting myself from another thread:

Get some food with 14% or 20% boon duration, get some damage, and count the reg heal in your combat log.

Here is a screenshoot of my combat log, once with 0% boon duration, then with 20% and then with 14%. The tooltips said 6s, 7.25s and 6.75s, but the numbers are indeed exactly 20% / 14% higher than the 0% value.

@Molch thank you very much for this information! This is something very important and I’m glad I learned it from you today!

Have a nice day and thank you for sharing!

After you use the block on shield there’s literally no point in staying in Shield anymore, the cooldown is long enough for you to swap to your other weaponset and back, and it will still be on cooldown. Skill 5 on shield you want to combo with Sigil of Concentration anyway.

The trick to using Sigil of Concentration properly is to only cast quickness skills when it’s active, this means going full yolo with Continuum Split, weapon swap, spam all skills, CS, spam more skills (If there’s no break in between you can just about make it). Or you can take the easy route and Continuum Split, weapon swap, spam all skills, come out of CS. Wait for weapon swap to come off cooldown, then weapon swap and using your wells here. Both ways achieve the exact same result. The 2nd option is also useful for when you need to do other stuff like positioning yourself correctly.

The important thing is to never cast anything outside of the Sigil of Concentration.

I like that the OP showed multiple ways to get the same amount of boon duration, but with Sigil of Concentration is just vastly superior.
