The Hidden Forest

Hello all has anyone had to farm the keys to get to the top of the Tower of frozen shadow lately. I am stuck on the 3rd floor trying to get the Enraged Shadowbeast to spawn. I have been slaying the entire level over and over because I read that he can spawn when you kill any mob on the floor. I've logged about 15 hours over 5 or 6 days trying to acquire this key was trying to see if anyone has any insight on how to make this mob spawn or maybe he just cant spawn at the moment. Hopefully I can get lucky and make my way to the top because Tserrina is the last mob i need to finish the World Boss hunter quest

I have found him to spawn only with the other shadow beasts, and I think his ph is in the room with the table, if I remember right. Kill them all, over and over, and you should be rewarded.

Thanks so much. Finally got it to spawn killed it then got the other 3 levels in about an hour. Ran to the top got ready to kill The world boss and realized she wasn't up. O it was so anti climatic. But thanks again

"/ass cha" at the entrance, and you'll know, for the future.

Yeah I just hadn't checked cause I hadn't expected to get the other keys so fast and when I got it I was so excited.
