Sacred Reservoir final boss room filled with monsters

If you accidentally enter the final boss room on Sacred Reservoirs and have Delirium or breach active - or in summary simply have monsters on you - they'll just kill you cause you cannot fight back or escape due to a "cutscene".

fully juiced map gone, what if you're hardcore and this is the way you die? This was utterly frustrating.

Please fix^^

Can certainly agree that this map needs it's boss arena reworked.

Not able to use any skills as you move forward. You are forced to walk. Can't roll.

If you have ANY mobs in that area, as in my case I had an abyss spawn in the arena and the mobs continuously swarmed me so I couldn't escape and was forced to log out or die, good luck starting the encounter (which takes forever to actually start so you can do anything).

Either remove the inability to attack, run and or roll, or make it so no extra mobs can spawn there. Please.
