I’m currently trying to improve my Showdown Tower map as I go through the event… filling in gaps, correcting door mappings and adding trainer names as I find out the information. Floor 7+ I believe are 100% accurate, but the earlier floors I skipped over a bit last time to save myself the tickets for the testing on the later floors.
If anyone spots anything that is wrong please do let me know, either in a PM or here. Otherwise, hope you find the guide useful for tracking down / avoiding those trainers!
