 - 点击干员显示攻击范围和底部按钮（「撤退」回到整备区、「出售 +1」）；右键 / 长按查看详细信息：头像旁是盟约，下面第一项就是干员的**特质**（如「休整期结束时 …」），之后是特性、属性、攻击范围、技能、模组、装备、天赋。属性是**实时数值**：作战中每秒刷新 4 次（当前生命、攻击、防御、法抗、攻击间隔、阻挡），休整期显示棋盘上的干员**开战时**的数值（已算入装备、盟约层数、特质、策略与机变效果）；高于基础值为绿色、低于为红色并标出差值（攻击间隔变短算增益），鼠标悬停可看基础值。
 - **召唤物手动摆放**：把带可部署召唤物的干员放上棋盘后，它的召唤物会进入整备区（赫默的医疗探机、巫恋的诅咒娃娃、凯瑟琳的 2 个支援装置、浊心斯卡蒂的海嗣、伺夜的狼群、缪尔赛思的流形；同一干员的召唤物叠在一格，不占部署位），像干员一样拖到棋盘上并选方向。凯瑟琳的支援装置给**它面朝的那一格**上的干员加屏障，所以要放在干员旁边、朝向干员。**战术家的援军**（伺夜的狼群、缪尔赛思的流形，也就是选战术点）和官方一样**只能放在召唤者的攻击范围内**：拖动时只有这些格子会亮起；之后在原地给战术家换朝向时，不在新攻击范围里的援军会退回整备区（还在范围里的保持不动；整备区和临时整备区都满、援军无处可退时，这次换朝向不生效并提示「整备区已满」）。撤退或出售干员时它的召唤物一起移除；**移动干员到别的格子时（包括把召唤物拖到干员身上交换位置），它已摆放的召唤物会退回整备区**，需要重新摆放。整备区满时退回的召唤物进入临时整备区，休整期结束还没处理的会在下一回合重新回到整备区。
 - 作战中：海嗣、狼群、流形、支援装置开战时就在摆放的位置部署；医疗探机、诅咒娃娃开战时也在摆放的位置免费部署一次（持续 10 / 15 秒，和官方一样不需要先开技能），之后所属干员每次发动技能时再次在原位出现；所属干员被击倒、再部署回场时，技能给的那一个如果还没出现，会立刻出现。巫恋退场时诅咒娃娃随之撤退，赫默退场时已出现的医疗探机不受影响。医疗探机、诅咒娃娃、支援装置、海嗣没有摆放就不会出现；狼群、流形（战术家的援军）没有摆放时会在战术点出现。
-- **阻挡**看接触：干员阻挡中心距离约 0.7 格以内、与它接触的敌人（地面干员挡不住飞行和近地悬浮的敌人）。敌人卡在两名干员之间时，阻挡它的干员倒下、撤退或被晕眩后，另一名仍与它接触、还有空余阻挡数的干员会**立刻接替阻挡**；都没有空位时敌人才会走掉。迎面走来的敌人会停在干员格子前面。**阻挡了就一定能打到**：任何干员（包括站在近战位的远程干员和召唤物）总能攻击自己阻挡的敌人，不管它在不在攻击范围内、在干员哪一侧，并且优先攻击它（医疗干员和「停止攻击」类技能期间除外；技能原文另有限制的也按原文：普罗旺斯二技能开启时不以生命值高于 80% 的敌人为目标，寒檀二技能的冰凌随机落在攻击范围内的地块上）。

 - 开战时干员按**从上到下、从左到右**的顺序部署，召唤物在所有干员之后。被阻挡的敌人先打阻挡它的干员；没被阻挡的远程敌人先打嘲讽等级高的，同级时打最后部署的（召唤物、靠下靠右的干员和刚再部署的干员更容易挨打）。隐匿的干员只会被它阻挡的敌人攻击；**迷彩**（如忍冬三技能期间击倒敌人后、寒芒克洛丝一技能）同样只会被它阻挡的敌人攻击，也显示为半透明，但它不算隐匿（不触发叙拉古等「隐匿时」效果）。叙拉古的隐匿按时（32 秒 + 每层 0.4 秒）结束；忍冬的迷彩按官方持续到她下一次开技能。
 - **技能自动释放**按官方「技能策略」：一般的手动技能在技能就绪、即将攻击 / 治疗且初始攻击范围内有敌人（治疗技能：有受伤的队友）时释放；**带独立技能范围**的技能（如德克萨斯「剑雨」、凛御银灰「御敌的锋锐」、锏「归于宁静」，不含「攻击范围扩大」类）在**技能范围内出现敌人**时就释放，不必先攻击；**重装干员**的手动技能在受到伤害时释放；执旗手 / 战术家 / 吟游者技能就绪即释放，解放者 / 阵法术师在初始攻击范围内有敌人时释放。**自动触发**的技能按其本身规则，例如古米「备用军粮」在身边（技能范围内）有受伤的队友时就会发动，下一次攻击改为治疗该队友（不用先接敌；她的二技能「食粮烹制」是手动技能，按重装规则在受到伤害时释放）；塞雷娅「急救」在她即将攻击时、身边有生命不高于一半的队友才发动，这次攻击直接改为治疗；新约能天使二技能的护盾按官方给攻击范围内**仇恨最高**的队友（嘲讽等级高的优先，同级时给最后部署的），不一定是站在最前面挨打的那个。手动技能的自动释放有 3 秒冷却：开战部署后先等 3 秒，之后同一干员两次自动释放至少间隔 3 秒（可充能的技能不会同时放完）。
 - **推开 / 拉拽**按官方「力度 − 重量」决定距离：例如野鬃二技能（中等力度）把重量 0 / 1 / 2 / 3 的敌人推开约 2.1 / 1.7 / 0.4 / 0.1 格，重量 4 以上推不动——轻型敌人反而推得更远。野鬃二技能沿她的朝向推开：正前方 45° 以内按上面的距离，身后、侧面或贴身的敌人只被轻推一下（约 0.4 格以内）；琳琅诗怀雅三技能的金币则从她身边向外推开。攻击速度最低为 20（沼泽、寒霜等减速叠满时也不会更慢）。
