How can I enter Morshabaal's room?

Question

Today, January 12th, 2022, Morshabaal spawned on Gentebra. I happen to have a level 120 EK there and I tried to go in where it spawns - for science. Turns out once I step on the teleport I got the following message:

12:46 You don't dare to enter the fight!

I suspect there's either a level restriction or I would need to have killed Orshabaal before, but I'm not sure.

Just saw a level 161 going in. Perhaps level 150 minimum?

161 died straight away. Do not enter on low levels… there should be higher cap for entering this room.  and Morshabaal seems to be immortal :X

interesting! Any videos about the boss?

After a player enters the room, you have 30-35 minutes to kill Morshabaal. If he doesn't die before then, he will heal back to full health.

Apparently it does not require a specific level
