You generate tons of quickness with this build via several sources. We'll talk about the big ones here:

This skill is very simple to use. Simply drop it on the group while farming for a ton of Quickness. You can use with 2 or 3 clones before this skill to effectively "Reduce" the cooldown of it. It is generally advised to only use this skill when Continuum Split is available OR if the fight is about to end.
This skill is basically a mini Time Warp and follows basically all the same rules. Be sure to stand it it so you get more quickness.
This is your primary source of quickness and is a trait you should become intimately familiar with. It provides quickness to the closest 4 people in your subgroup; if there are no subgroup members in range, it will target squad members. If there are no squad members in range, it targets the nearest 4 people.
  • - Provides: All of it
Your bread and butter skill. We'll talk about this further down.

Other Boons

On top of providing Quickness Quickness to nearby allies, you also can provide nearly every boon in the game to yourself. This playstyle generally requires and , but is a ton of fun.

A valuable well that you should try to sneak into CS if possible. If you want to provide 100% alacrity alongside your Quickness, this is required.
Mentioned here due to how strong a stunbreak that provides Stab to allies can be. Highly recommended for most zergs.
Alac on yourself for every clone shattered.
Provides you with an arsenal of boons you can call upon at any moment.

Clone Generation

You have several ways to generate clones. As a general rule, try to always shatter at 3 clones if taking . This isn't always required, especially in short fights, but will drastically boost your boon output in longer fights.

Use the following skills to generate a clone. There is no real priority here:

  • Shatter at 3 clones
  • (stand in damage on purpose to proc this)
  • Your phantasms become a clone once they finish their attack and disappear (about 2-3 seconds after you summon them).

General Rotation

Unlike most open world builds, this one actually has something resembling a rotation. Our primary goal with this build is to provide allies with 100% Quickness Quickness uptime while also dealing relatively high DPS to the boss. To do this, we have to be very good about clone management.

Here is our generic opener:

Part 1

To start, generate 3 clones as fast as you can. A good way to do this is:

  1. Weapon Swap
  • It is very important that you perform this very quickly, so you can have clones spawn during the next phase.

Part 2

Following this, immediately shatter your and fit as many skills as you can into it. This will change with each casting of CS, but in general the big ones to watch out for are:

  • Any phantasm

During this phase, you will have three clones spawn from the three phantasms you spawned moments ago. When you see three clones on your bar, shatter , followed by and . Be very careful not to shatter as CS ends, as you may throw your skill on cooldown.

Part 3

The final stage of the opener is simple. Because of the CS reset, you will have again, so you can decide to drop this now if the fight is short or hold onto it for your next CS.

  • will still be active for a few seconds after your CS ends, so wait for it to end while generating clones. Fill with damage skills.
  • A few moments after it ends, shatter with 3 clones, followed immediately by . Around this time you will need to swap back to Greatsword for more clones, and your will be up.
  • When the quickness on your bar reaches about half duration, use .

This opener will grant quickness for quite a while and a lot of open world bosses will be dead in this time.

  • For those that aren't, simply continue to generate clones and shatter them.
  • Prioritize when shattering, and try not to shatter with less than 3 clones unless it's a short fight.
  • Use any time your personal quickness drops to around half.

When is up again, repeat the opener.

Use often. Generally, you want to Summon a Phantasm, weapon swap, Summon your other Phantasm, hit , then re-summon that Phantasm again.

One of my all-time favorite zerg builds. Very durable; my only complaint is that the gear is annoying to get.
