# “回声”战斗系统
“回声”是基于其他玩家的属性数据生成的强力敌人。
它们：
* 有几率在每个房间中刷新，且等级与你相近
* 拥有与被复制玩家完全一致的生命值与法力值
* 会展示该玩家的名字、等级、派系以及外观皮肤
Dungetron 5000 和 Dungetron Underhaul 均有概率刷新“回声”。
“回声”只会在玩家在地下城中到达第 10 层后才会出现。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.gigaverse.io/zh/zhan-dou/hui-sheng-zhan-dou-xi-tong.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
