遗物
先看它在什么时候真的有用
在雷电增伤之外，每次触发转化都会给下一发子弹塞进额外弹丸和高额攻击加成。价值完全取决于触发频率：在转化触发频繁的雷电流里，每次触发都是一轮小爆发；触发少就只是普通增伤件。
带入规划器怎么决定要不要拿
Take it when your current route already produces the lightning, extra shot signals. The value comes from repeating that event, not from the item name or rarity alone.
If none of its triggers are happening yet, keep the slot open for a pick that strengthens the engine already on screen.
