The The Hidden Bowling Alley is found in The Hidden City, after being revealed by Fire When Ready.
A primary stat of 125 is suggested. If your main stat isn't high enough, you'll see the following message:
(It is recommended that you have at least 125 <mainstat> to adventure here.)
- This zone might be too tough for you.
- Bowling balls are not 100% drops (only 40%). Boost Items from Monsters as needed.
- Bowling balls can be closeted to postpone the noncombat. Doing this does not save you any turns, but getting all your combats together may allow you to conserve buffs.
