Terraria: Thorium Mod

Ever wanted to fight new bosses? Find, craft and collect new rare items? Abuse new mechanics? Build fancier looking houses for new NPCs? Look no further.

Thanks to tModLoader, Terraria modding is taken to the next level, for both mod developers and users. A product of this, the Thorium Mod, is one of the most expansive mods for Terraria. With over 2000 new items, 11 challenging new boss fights, hordes of new enemies, an entirely new biome and even three new classes, you'll soon be unable to play Terraria without the Thorium Mod installed!
