Improves the end without disturbing vanilla. Adds a new, rarer biome with chorus stem trees. These trees can be harvested for dead saplings, and dead saplings converted into oak saplings. Chorus sprouts also grow on the edge of the biome, these can be crafted into blaze powder or chorus bulbs. End stone can be crafted into cobblestone with one chorus flower in the center of 8 endstone.
A new mob called the Aura can be summoned as well. Placing a chorus stem on top of a Raw Energy Block(these spawn in the sky), with 4 chorus bulbs around it, will summon the Aura if you have over 10 xp levels.
