技能
先看它在什么时候真的有用
处决型加成：[猎魔银箭]对血量掉到一半以下的敌人有一大截最终伤害加成，实战里就是把精英和 Boss 战最磨人的收尾阶段砍短。它必须搭配稳定的出箭频率才有意义，银箭产量不足的 Build 里别拿。
带入规划器怎么决定要不要拿
Take it when your current route already produces the extra shot, 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.
