How to Quickly Cycle NPCs

To efficiently find specific NPCs, you can exploit the random spawning mechanics. Choose a small strip, such as the one on the left or right side of Sunlit Cavern. For instance, taking the right strip allows quick access to looped pathways near the Sunlit Cavern entrances where an NPC like Leticia might spawn. You can repeatedly traverse these paths until you find the NPC.

After finding an NPC, enter the nearest Hideaway and then return to the same strip. The NPC's position and identity may change. By repeating this process, you can cycle through NPCs, hoping to find a different one each time, though it will often be the usual NPC for that strip.
