Shop Variations
Shop variations are hardcoded and chosen under the following rules. The events to trigger a variation are found in World State Data.

- Moon Cave Interior
- City Checkpoint
- Kusa Village
- Sasa Sanctuary
- Kamiki Village - After fighting Tei
- Shinshu Field (Healed)
- Agata Forest (Healed)
- Taka Pass (Healed)
For Seian City (Commoner's Quarters), an unknown condition is required to be met before any shop variations are checked. Then there are 2 variations:
- Oni Island (Ninetails Arena) (40) event 1
- Wawku Shrine (Lechku and Nechku Arena) (64) event 2
