武器
先看它在什么时候真的有用
先钉钉子，然后让天雷替你干活：被钢钉标记的敌人每秒挨自动落雷，落雷数量随弹丸数增加，换弹还能引爆全部标记打出三倍伤害。等于自带引爆键的挂机式多目标输出，非常适合堆弹丸的清群 Build。
带入规划器怎么决定要不要拿
Keep it when lightning 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.
