About this Mod
An End update made for SpookyJam!
This mod adds one* new biome, the Corrupted End, consisting of Dragon Stone and End Corals. On the bottom of the islands, find Skelrite, smelt it into Dragon Scales, and craft the Dragon Shell. For some reason, this helmet enables faster mining, but beware—it also can't be taken off.
*technically three biomes; the End is very silly.
