武器
先看它在什么时候真的有用
给你搭一套冰霜炮塔网：每次换弹留下一个雪人，远程丢雪球加近身冰环，所有伤害都有概率触发【冻结】，最多同时三个。高换弹频率的 Build 能把战场变成自动运转的冷冻库，你只管拉扯走位。
带入规划器怎么决定要不要拿
Keep it when frost is the Transmutation your current relics and Tarot already reference. Its firing rhythm and effect matter more than the rarity label.
Switching weapons can abandon element progress. Only make the move when the new effect fixes a real problem or the old engine has stopped appearing.
