+# 移动戒指（203 服务端）
+
+40250 的移动戒指 70058（任务物品，30 级可用）通过 `special_item_group.txt` 的 10031 组触发任务 `ring_warp`：
+选择本国一村 / 二村、升龙谷、影悲沙漠、舒寒山、导炎大地后传送。原版能用 50 次、每次冷却 30 分钟
+（item_proto value0 / value1，记在物品 socket 0 / 1 里），用完就消失。
+
+这里的 `ring_warp.quest` 去掉了次数和冷却：不再读写 socket，戒指不会消耗。在百店老板娘的商城里卖
+（`../npc-shops/item-mall`，1 金币）。
+
+    sh install.sh    # 在服务器上，从本目录运行；然后重启 db 和 game
+
+`install.sh` 会备份到 `/root/backup-ringwarp/<时间>`，把任务转成 GBK 换掉 `ring_warp.quest`，用 `make.py` 重新编译
+全部任务，并把服务端的物品名（`item_names.txt`、DB `item_proto.locale_name`）改成「移动戒指」。
