The ground floor is the second zone in The Castle in the Clouds in the Sky and is unlocked as part of the Giant Trash Quest.
A primary stat of 110 is suggested. If your main stat isn't high enough, you'll see the following message:
(It is recommended that you have at least 110 <mainstat> to adventure here.)
- This zone might be too tough for you.
- Non-combats in this zone have a cap of 9 turns between occurrences. (10 turns if the previous non-combat did not take a turn.)
- When the third level of the Naughty Sorceress' tower is unlocked, the Home on the Free Range non-combat gains 3 copies (going from 1-in-4 to 4-in-7 on top of noncombat queue mechanics), becoming much more likely to occur.
