你可以将他赎回到你的城镇中心(字面意思就是你付给其他玩家一些金子)，也可以通过杀死他周围所有的敌人来营救他并让他自愈。

You can either ransom him back to your town center (literally paying the other player some gold), or you can rescue him by killing all the nearby enemies and allowing him to heal back up.

杀死一个敌人后的短时间内，你的所有枪械会在原有的元素伤害类型之外，被暂时附上冰冻元素伤害，如果你的枪械原本就造成冰冻系伤害，那么它的伤害将会增加。

After killing an enemy, all of your guns deal cryo damage along with any other element they normally deal for a short time. If your gun already does cryo damage then it deals additional cryo damage.
