Frost cancelled his [summon ice golem] spell before heading down the stairs to the 2nd floor. No treasure or chest was given for beating the first floor's boss but after the 3rd floor's boss there was a decent chance of one appearing, but the danger also increased. After the 3rd floor there is either a D-rank monster as the boss or multiple E-ranks, far more difficult to defeat than the ice golem of the first floor.
Once he descended the stairs Frost appeared on the second floor, the décor and environment was the exact same throughout the monster lair, covered in ice. The temperature grew several degrees colder after every floor and after the 3rd floor it was possible to discover some ice aspected herbs, many adventurers entered for these herbs as their goal.
