The battle begins with the boss. Then his assistant comes out and the boss immune until the kill add. I entered priority. (<CustomBehavior File = "KillUntilComplete" ImmediatelySwitchToHighestPriorityTarget = "True"). The essence of the problem is this. After the exit add and the target changes from boss to him. Singular does not use skills on it. It only hits autoattacks and then adds it to the ignore. (Out of range / line of sight for 20.0 secons). After that, he again asttack the boss in the immune. The problem, as I understood it, is that despite the fact that add has a big hitbox. Singular thinks he is out of radius. I tried other available routines, there are also my own problems, but they use skills on it. [KillUntilComplete-7b5abb(info)] Current POI is not the best target. Changing. [Singular] Switching to BotPoi: ADD [Singular] Combat, Pull Target ADD out of range/line of sight for 20.0 seconds, blacklisting for 00:00:20 and clearing BotPoi [Singular] CurrentTarget ADD blacklisted and not in combat with so clearing target! [Singular] Current target invalid. Switching to aggroed mob BOSS!
