X-Bar Theory
A mod adding growable tree dungeons battle towers!
This mod originally aimed to implement giant tree dungeons, but #flirora lost motivation for 2 whole months when they had to implement tree branches.
To start, obtain a Heart of the Skies from an ominous vault in a trial chamber. Apply it on a block of stone bricks, and a tower will pop up! Make sure to do this away from any builds you care about, since it’ll be huge.
The tower contains many trial spawners, which have a chance of dropping Celestial Tokens when you finish the trial. Or if you complete an ominous trial, they might drop the rarer Auroran Tokens instead. These can be spent at the Celestial Nexus that generates at the heart of the tower.
