we currently have 47 floors, so the new floors will start at level 95 for floor 48 (assuming they follow the same trend as the previous floors), accessing a new floor every 2 levels. This means you'll need 119 dungeoneering to access all the floors, they better dish out some amazing base xp for 48+ prestige, because we'll need some serious XP to make level 100+ reasonable goals.
This also means that every Tier 11 item will be available now. I'm really hoping the saggitarian body is dropped by one of the first 4 bosses. The magic defense on that would help a lot for Occult floor, and maybe warped depending on how many shade/mages/ghosts/necromancers there are on the floors. We also need to find out what new monsters they'll bring.
My idea for binds at 100 dg are Saggitarian body, primal legs, primal b axe. We'll see what happens from there.
