+1 nice idea to m7 floor as arena but:
- bosses should be the ones of mauso, the so called "mini" arachna,captain,ferrix,frostir..
- agree perfectly with abuze about timed runs & new jewels
- agree with your loot table and name of the chests xD
- drag staff shouldnt affect those bosses and in this arena rogues needs to deal great damage as they do in elite planar arena, or this class will not be so useful.
