GUTS is Runic Games® in-house development tool for Torchlight II™. Using GUTS, you can modify almost everything about the game, from item and skill balance, to level layouts, animations, quests, and much more.

It may no be user friendly or straight foward as one should want but that's the reason for this wiki and TorchModders, for Modders to help each other.
