In-Depth Guide
深度解析：Sunday 实战怎么玩
Sunday 是 Imaginary Harmony，行动提前+召唤协同辅助，定位是召唤/自动攻击核心的最佳搭档。一句话结论：主 C 是 Jing Yuan/Phainon/Mydei 这类，选他。
定位与机制
Sunday 给目标 ally 及其召唤物行动提前，并提升暴击伤害与能量，是召唤系与自动攻击核心的专属拉条。他的 memosprite 还能配合自动攻击主 C。
伤害构成与手法
循环是战技提前主 C+召唤物 → 大招指定 The Beatified（暴伤/能量）→ 普攻。他让召唤物的行动频率直接拉满，是 Jing Yuan 神君/Phainon 变身的核心增益。
配队思路
最适合 Jing Yuan、Phainon、Mydei、Aglaea 这类召唤/自动攻击核心；配一个生存位即可成型。没有他对这些主 C 的上限影响很大。
养成与投入
签名 A Grounded Ascent 强化提前与暴伤，四星 Past and Future 可用。遗器 Messenger Traversing Hackerspace 4 件 + Broken Keel，主堆速度与暴伤。
适用场景与局限
召唤/自动攻击队里不可替代，是多个顶级主 C 的黄金辅助；泛用性不如 Robin，对非召唤主 C 价值有限。需要速度调配先于主 C 行动。
总结
抽他如果你主 C 是 Jing Yuan/Phainon/Mydei 等召唤或自动攻击型、追求更高单核上限；这些体系里他专一且关键。已有上述主 C 的账号收益最大。
