Nothing special: 5 floors, with 5% chance to have the boss on last floor. On non-boss floors, you have 3 or 4 enemies. This is random, no way you can do something to have more or less ennemies. One of them is always the Gorger, the other are randomly chosen from a table of 17 possible enemies: 3x sword, 3x spear, 3x bow, 3x bomber, 4x mages (one for each element), 1x golden (this is only for CC3, I didn't bother looking at monster in lower CC) And of course, monter and trap positions are randomly chosen
