## Guides

### BBS Equipment Builds

What is BBS and what do the meters mean?

BBS, an official Chinese equivalent to HoYoLAB, has a wiki on which they present Captains with what is generally agreed on to be the best equipment builds available, aimed towards both the new and the veteran Captains. BBS separates gear recommendations by what we'll refer to as "tiers" and "criteria".

Tiers serve as means of separating all the different gear builds. Available tiers:

* **Recommended Equipment:** Equipment build suited for what the battlesuit does the best. A lot of the times it's unique to just one specific battlesuit.
* **Auxiliary Equipment:** Extra equipment build specifically for Supports, providing Captains with more alternatives.
* **Universal Equipment:** Equipment build that is interchangeable with other characters performing the same role, without many drawbacks, or the most popular alternative to recommend equipment.
* **Transitional Equipment:** Equipment build that can be used as a placeholder until a better gear is acquired. Easy to get since most if not all items are farmable. Good when starting out.

Criteria are visualized via meters that fill until they reach 100% - at which point the build fully meets the set criteria. Available criteria:

* **Offensive Ability:** How much does the build help the battlesuit deal more dmg?
* **Functionality:** How functional the build is when put together?
* **Compatibility:** How well does the build fit the battlesuit's role/kit?
