Tower of Sins

The Tower of Sins is the first Dungeoneering tower you can explore outside of Daemonheim. In total there are eight floors, and each requires a certain Dungeoneering level to enter. It is also involved in a quest called Zamorak's Brothers-in-arms. Unlike Daemonheim, you can take your items with you.

WARNING: This tower contains monsters up to level 1050! If you die in here, you will loose ALL of your items! Also, there will be NO gravestone upon death and other players can pick up your items immediately! Take the items you do not mind loosing!

Starting off
To enter the tower, talk to the knight, Sir Baening. There, you get to learn the history of the tower and it's origins. First, you have to defeat a Savage Brute before entering the first floor. The trapdoor is for the eighth boss you have to face, and you have to defeat the 7 above ground before gaining entrance.

Bosses
In total, there are eight bosses in the tower. The first one is Asmodeus, the most lowest level boss at level 85. He is just a human warrior who is often charming at times. As he represents lust, he will summon level 64 Female Paladins to assist him. He shouldn't be too hard, but he has strong magical attacks.

The second is a giant brute named Beezlebub. He's level 120 and uses primarily melee. He's harder than Asmodeus, but he uses only melee and such. He represents gluttony and is not that intelligent.
