短答案
从 Long Tong 的Amber companion / element chain路线开始
Hard and above reward the route's coherent damage, but only if Fury and companion uptime are safe enough to repeat.
这里的“推荐”是根据难度风险和当前数据选出的清晰起点，不是证明某个猎人永远最强。Steam 百分比是拥有者快照，不能当作单局成功率；Reality 的数字高于 Hell，也不能被解释成顺序留存。
地狱 难度改变了什么
A high-pressure tier where one unrecoverable moment often ends the run. Protect movement, reload uptime, and a fallback before greedier scaling.
Choose one element and keep Amber active.
A Fire weapon, Dragon Breath, and companion or Fire support.
检查：The route should feel like one engine, not a gun plus an unrelated pet.
Raise companion event frequency.
Multiple Dragon Breaths, Ever-Burning Dragon Flame, Fire rate, and survival.
检查：If Fury is ending the run, take safety before another damage multiplier.
Use the element chain for elite and boss windows.
Element-matched relics, companion damage, and a reliable burst card.
检查：A second element is a last resort, not an upgrade path.
Boss 与清怪优先级
Bosses reward sustained Fire pressure and Ever-Burning coverage. Use Fury as a finishing window and keep the weapon firing while Amber works.
Let Dragon Breath and spread effects handle packs while the main weapon preserves safe spacing. If rooms overwhelm you, choose coverage before the highest boss ceiling.
核心缺失时的补救
Keep the element your current weapon and relics already support, then prioritize companion uptime, frequency, and survival.
不要：Do not hold an empty slot for one exact Fire gun while Amber is already contributing with another element.
