Herald - Celestial Herald Roamer - MetaBattle

General

Invoking a legend resets energy to 50, procs various traits such as 唤醒折磨 or 精魂清算, and could even trigger the sigils of your active weapon set (if they are not on CD) among other things. Swapping legends is basically the main resource management tool in the build - swap whenever you're out of CDs or low on energy.
Start on Dragon stance (Glint) and while still in the base activate the following 4 upkeep skills for party buffing:
- 自然多面体 (use its active when your energy is about to hit 0)
- 元素多面体
- 力量多面体
- 黑暗多面体
Swapping legends deactivates the upkeep skills of that legend without sending them on full CD.
黑暗多面体 is one of the most versatile and strongest skills in the build:
- 黑暗凝视 is a cheap stun breaker and one of the few skills in the game that can reveal stealthed targets.
- The 目盲 from Gaze can be used to avoid powerful attacks without wasting dodges, and can help you stomp warriors / revenants / engineers / rangers by blinding their downed CC. Even mesmers can be stomped with a little luck because of the AoE reveal.
- If you're 目盲 while channeling 混乱疾风 you can use 黑暗凝视 at the last moment before the skill finishes its animation - in this case Gaze of Darkness will miss instead of your elite.
混乱疾风 can be used to knock downed opponents away from their rezzing teammates, or to knock them off of capture points - this allows you to take the cap while bleeding them out, delaying their respawn.
Upkeep skills continue to provide their bonuses for a few seconds after their chain skills have been used up.
Shiro's quite good at chasing targets due to 位面穿行. The unblockable attacks coupled with 急速 make this especially great at initiating fighs and immediately putting pressure on enemies, but the high cost can often force you to swap to Glint for an energy refill shortly after.

Damage

Both weapon sets and both legends have great offensive capabilities.
(Shiro) is mainly for single target. and can either be used to deliver burst damage or even to boost the damage of your filler attacks like the Spear auto while all your other skills are on CD, or if you want to stay in range.
- Maintaining costs quite a lot of energy, use it only for a few seconds at a time when you're sure that you can keep landing hits.
when used on Shiro is a cheap and strong AoE skill with boon removal. The passive bonus lingers for a few seconds, giving you armor ignoring damage procs.
(Glint) brings midrange AoE pressure to the table. Using some of your upkeep skills just to follow up with their chain skill is a perfectly fine thing to do, and + provide decent damage even from range. These are also extremely cheap, so you can weave them into burst combos anytime.
Mace is fairly simple, just use ⇒ in this order (for stacking) whenever you can.
The spear autoattack automatically flips between melee and ranged versions depending on your distance to the target.
Spear is built around .
- The skill becomes more powerful the more you use it (you can see the stacks above the right side if your skill bar), and swapping weapons at 3 stacks of AR does an AoE attack.
- It has multiple charges and you should never sit at max charges for too long, so keep using this as much as possible.
- Every other Spear skill reduces its CD by a certain amount.
- It'd make sense to use this skill right as you swap to Spear so you can start reducing its CD immediately with other skills, but (for CC) and (for evasion) often end up taking priority.
- The AoE ring is small and the skill's a bit slow, so it can be hard to land on moving targets. Works great as a followup to CC though, or if you're getting attacked in melee in which case the enemy isn't moving around as much.
- The weapon swap bonus at 3 stacks is more of just a nice bonus. Don't camp spear just because you're chasing the 3rd stack, especially if you're out of CDs or getting focused by the enemy team.

Sustain

Every weapon and legend offers some level of survivability.
Spear and Shiro are the least defensive ones but even these two have evade frames, namely on and .
Mace has which mitigates incoming strike damage through .
Both of the shield skills provide healing, cleansing and even blocking, although is a much stronger block than . CH can also function as a time-out button - you can't move, but at least you should be protected from most attacks while stabilizing yourself as every pulse of this skill heals and cleanses conditions. At least you can move while using EoE though, and EoE can even be shared with allies, adding a small bit of group support to the build's toolkit.
by itself won't help you against damaging conditions, but it does cleanse several movement-impairing ones all at once. Using this before your other condi removals will significantly increase the odds of those removing damaging conditions (like shield skills or when used on Glint).
's chain effect is your jail free card - makes you immortal for the duration by converting all incoming damage into healing (except for fall damage). It's also by far your best tool for dealing with condition spikes. Some players may stop pressuring you once Face of Light's been activated, in this case you should just wait a couple of seconds before using Infuse Light. Make sure you get at least 10k healing out of this skill, try to predict when burst is coming and use Facet of Light in advance - FoL has a cast time thus cannot be used while stunned, but Infuse can.
can instantly apply even while CC'd, which makes it a really potent source of damage mitigation.
