~The Challenge Cubicle~
After a year or so of working on this it's finally open. Thank you everyone who helped!
You can find the entrance at the EventLand spawn, it's the portal with white wool and banners.
Progress from room to room each containing a challenge built by someone, beat it to advance to the next one. Most rooms have 2 exits, but not all.
The event has 4 different "endings", rooms with colored wool and signs. Take a screenshot of you winning one or more and post it here for the prize!
For each ending you find you can choose one colored shulkerbox (+1 for a total of 5 if you find all 4) me and BuuR have filled with items. You can't see what they are beforehand though!
