 - **晋升精锐**：3 名同名干员（无论是否部署）自动合成**精锐**（等级、技能、模组大幅提升；风丸只需 2 名），精锐不会再合成。如果被合成的干员里有**已经部署在战场上**的，精锐会直接出现在**那名干员的位置**（保持原来的朝向，不多占部署位；有两三名都在场上时，取最先部署的那名——最左一列优先，同一列从上到下）；否则精锐进入整备区（满了进入临时整备区）。原先配发的装备都退回整备区，需要重新配发；被合成干员的召唤物随之移除，场上的精锐会把自己的召唤物送进整备区。点选一张能合成的商店卡片时，精锐将出现的那一格会亮起金色边框，同时打开的详情卡里也会写明去向（「可晋升：精锐干员将出现在作战区原位置 / 将进入整备区」；详情卡会自动停靠在不遮挡这一格的一侧）。在回合开始或结算时因策略、奖励等完成的合成，精锐出现时同样会播放金色的晋升特效。
