 - 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（医疗干员除外：咒愈师以外的医疗挡住敌人时照常治疗队友，不会攻击它；「停止攻击」类技能期间也除外；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**逐列从左到右、每列从上到下**的顺序部署（最左一列最先，与阿戈尔吞噬「更靠左和靠上」的顺序相同），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、最右一列靠下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，没被它挡住的敌人的溅射、爆炸、范围技能、留下的伤害区域（包括假想敌：蚀裂被击倒后喷出的毒雾）以及深池伙友卫队、扎罗的减攻速光环也落不到它身上（和官方一样；写明「无视无法选择」的效果如污染秽蚀照常能打到，寒霜的减攻速光环和“墓碑”这类地图效果照常生效）；**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，但躲不开溅射、爆炸和范围伤害（同时打范围内所有单位的普通攻击——如“斩胄之剑”“破胄之锤”“灵幛”——打不到它），也不算隐匿（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。**蒂比起飞**期间只挡飞行敌人，地面敌人不会选她为目标（普通攻击、溅射、技能范围、燃烧区域和要选中目标的减益都落不到她身上）；飞行和悬浮敌人、写明「无视无法选择」的效果（如污染秽蚀）照常能打到她；地面敌人的光环和全场效果（如“墓碑”让全场攻击力、防御力减半）、她攻击敌人时招来的反制（如重装侦察兵的暴露）照常生效，起飞前已挂上的持续伤害也照常跳。

 - **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，落在她前方 2–4 格的范围（官方「范围2-4」）内的地面敌人和她阻挡的敌人身上。攻击速度最低为 20（沼泽、寒霜等减速叠满时也不会更慢）。
 - **元素损伤条**在单位自己的血条正下方：左边是元素图标，白条是剩余的元素值，只有真正爆发时才会耗尽；爆发后条变成元素的颜色、图标闪烁，在冷却期间慢慢回满（这段时间不会再积累元素损伤）。
 - **敌人**：远程敌人的射程按官方从干员的碰撞体积（半径 0.25 格）算起，比数据上的攻击范围半径远 0.25 格——例如萨卡兹枯朽战车（射程 2.2）能打到中心 2.45 格以内、站在低地的干员。没被阻挡的远程敌人每次攻击都会站定、播完攻击动作，两次攻击之间才继续前进。它的第一下攻击就是「秽蚀轰击」（在目标处留下半径 1.7、持续 10 秒的污染区：低地每秒 50、高台 25 点真实伤害，同名不叠加），被阻挡时普通攻击伤害翻倍。“萨科塔之翼”等血量第一次低于一半时会在原地小范围乱飞 5 秒（官方叫「恐惧」）；叙拉古、妮芙等干员造成的恐惧会让敌人朝远离干员的方向逃跑。隐匿的敌人只有被阻挡（或被揭示）时才能被选为攻击目标，溅射、技能的圆形范围伤害也打不到没被挡住的隐匿敌人（和官方一样）；阻挡解除后 3 秒内它仍然可以被选中（官方页面注明 0 秒或 1 秒的敌人按页面），之后才重新隐匿：深池逐火战士每次被击倒后先重生 1 秒，然后变成继续往前走的隐匿「余烬」（需要 5 次伤害击倒，护卫的「火灰」10 次），一般要用干员挡住它才能选中（挡住时它不再半透明；被阻挡时被击倒的，重生结束后约 2 秒内也能用远程或范围伤害补刀），10 秒内没打掉就满血站起来；敌人重生时身上的减速、恐惧等状态会被清空、技能冷却从头开始，被恐惧的逐火战士变成余烬后也能被挡住；转译基底·α 原始形态受到的伤害全部无效，受到第 4 次物理伤害、第 4 次法术伤害或被阻挡时花 2 秒变成寻仇者、特战术师或幽灵，之后才能被击倒。
