Introducing the Terraria Rebalanced and Expanded Project!
Made by certain Terraria fans who felt that 1.4 wasn't quite fitting to be the end of Terraria, this rather ambitious mod aims to fix all issues present in the vanilla game, balance or otherwise, and expand it where it currently feels lacking in content.
This mod's primary feature is all its changes to the vanilla game, but it is not at all exempt from having brand new content to explore!
And more! This mod may build itself off vanilla balance, but it is guaranteed to shake up your experience dramatically.
