遗物
先看它在什么时候真的有用
每次施放战技都会额外射出一发穿透炮弹，威力是当前武器的数倍，而且同时吃战技和子弹两类加成。战技流通用的强力输出件，打 Boss 和直线排列的怪群尤其好用。
带入规划器怎么决定要不要拿
Take it when your current route already produces the battle skill, boss 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.
