Weaver

The weaver's profession mechanic is weaving, letting you attune to two elements at once and combine their powers. Whenever you attune to a new element, it affects the first two weapon skills, and the previous element moves to affect the last two weapon skills. The third weapon skill, when attuned to two different elements, is a combination of both elements called a Dual Attack. Additionally, weavers have greatly reduced attunement cooldown.

Damage

There are several buffs you should aim to maintain to increase your damage. These are 超级元素, 迅速复仇, 愤怒元素, 火使训练, 长效怒火, and 烟花古物.

To accomplish this, you want to maximize uptime on 迅捷, 虚弱, and 燃烧 as well as typical offensive buffs ( 易伤, 威能, 激怒), using long-cooldown skills such as 风驰电掣 and 烈焰之攫 to proc 烟花古物, and juggling double-attunements when possible. This can be a lot to take it at once, so go slow learning this build. It's very simple once you get the rhythm for it, but can be overwhelming at first.

Rotate between 火焰协调 and 空气协调, making sure to double-attune to each when possible.
风驰电掣, 烈焰之攫 and 大地翻腾 will activate 烟花古物. (the relic doesn't care about the cooldown reduction from 火使训练 or 风使训练).
Use blast finishers in Fire Fields to generate 威能. Use 原始姿态 in 空气协调 to apply 易伤
