When a player uses a skill that deals continuous damage, enemies within the hit detection area can be damaged up to a maximum of 4 times by that skill. After reaching this limit, the enemy’s collision should ignore further hit detections from that skill only (effectively becoming invulnerable to it) until the skill ends. However, the enemy should not become completely invulnerable — they should still be able to take damage from other skills’ hit detections.
玩家释放技能进行持续攻击，在判定范围内的敌人受到伤害的最大次数设置为4，达到4次后敌人的碰撞就无视该技能的攻击判定（相当于仅仅对该技能无敌），直到技能结束。但是敌人并不是进入完全无敌，同时依然会接受其它技能的攻击判定。
