伤害与机制
Fugue 是击破体系辅助，能为敌人植入弱点并强化击破后的防御无视，是 Firefly/Boothill 击破轴的关键齿轮。Topaz 则是追击体系放大器，靠『Numby』标记敌人提升全队追击伤害，并给主 C 增伤。
最佳队友
Fugue 配 Firefly/Ruan Mei/Gallagher 的击破队，或替补 Ruan Mei 的位置。Topaz 配 Feixiao/Robin/Aventurine 这类追击队，是 Feixiao 体系的增伤核心。

Fugue 可用 Watchmaker 等击破辅助套装堆击破特攻与效果命中。Topaz 用 Worrisome Blissful + 追击相关套装，堆暴击、攻击与效果命中。
零氪与账号适配
零氪若玩击破（尤其已有 Firefly），Fugue 的植入弱点是质变；若玩 Feixiao 追击，Topaz 不可替代。两者按你想玩的主 C 体系选。
🎯 Verdict
选 Fugue 如果你走 Firefly/Boothill 击破体系、需要弱点植入与击破增益；选 Topaz 如果你走 Feixiao 追击体系、需要 Numby 增伤。两者是不同体系的专用辅助，按主 C 决定。
Which One Should You Choose?
If you need a nihility-style option, Topaz (Tier S) is the stronger pull. Fugue (Tier S) is the better pick when you already cover that role or want the cheaper account fit. Both are viable 2026 options.
Consider your account when deciding. Look at the units and weapons you already own, the teams you already have built, and the content you struggle with most. Both Topaz and Fugue are strong — the right choice depends on which fills a bigger gap in your roster.
