100% guaranteed death on act 2/act 2(cruel)/Copper Citadel Boss.

Its always a guaranteed death on the boss on act 2 if you damage him quite fast enough and he ends up summoning the sandstorm so he can proceed in phase 2 but the problem is Asala will be too late to summon the shield/force field to protect you... giving you a guaranteed 100% death. sure its no problem on act 2 and act 2 (cruel) coz you can respawn but doing it on atlas map Copper Citadel where you cant respawn and re-take the boss is so punishing to time and effort, specially to Resource. trying to juice up your waystone using exalts and vaal to get a 400-500% waystone drop and the EXP loss. its so frustarting... knowing you cant finish the copper citadel and cannot proceed to arbiter of ash. already tried 3x and always Asala will be too late to protect you from the sand storm... i even tried slowing my dps yet 100% certain death. hopefully this could be fix... coz its kind of frustrating trying to map citadel and spending resources just to die coz of bugged npc mechanics.

I died on 2/3 copper citadels for the exact same reason, I also think that’s why the price is way higher for this fragment compared to the others
