This mod allows you to generate and run through trial chambers (and other jigsaw-based structures).
Begin by creating a map. You can add modifiers to the map by dropping items onto the item (like a bundle). Example modifiers: speed, trial omen, replace decorated pot loot table with another loot table, replace trial spawner mobs.
Insert the map into a map device, then send a redstone signal to the device.
Once the structure is generated, single-use portals will be created. Right-click the portal to enter.
These are the core objects of the mod. Place the map item into the map device.
I placed the desired map item into the device and sent a redstone pulse.
Right-clicking the portal takes you to the structure defined by the map (in this case, a trial chamber).
This map had an attached modifier such that pots may drop bastion loot.
This map had an attached modifier such that breeze spawners always change into blaze spawners.
