BOSS THE BALCK CROW BECOMES INVINCIBLE

hi there , want to report a bug i found today ... i was ruining a waystone tier 3 today whit my cold bild chronomancer , as i progress to the boss( the black crow) and start the fight right after i take around 50% of the boss hp he just become invincible and charges after me and did not go to second stage of the fight ! and then i had to die and hope it is going to be fine next time but it was not ! evry time the boss got half of the hf he just becomes invincible and charges none stop ... the last try i even spent like around 5 min runing around in hope it will end but it did not . ... pls look in to it !

The bug is that he becomes invincible if you damage him too quickly in his first phase.

You can bypass death by jumping out the fence using a Travel Skill like Leap Slam or Thunderous Leap then portal out the map.

As far as i tried i couldn't reset the Map, i had to abandon it.
