Ex Inopia is an addon for 1.7 to Ex Nihilo meant to improve integration between it and Tinkers' Construct. Notable features include an Ex Nihilo Tinkers' Construct hammer, copying smeltery recipes to work in the crucible, a more challenging method of lava creation in the crucible, and a method of obtaining stones from the Chisel mod.

This mod was designed for a SkyBlock based pack I was working on in 2015 called KnightSkies alongside KnightPeripherals which had features to allow ComputerCraft tutles to use Ex Nihilo hammers and sieves. Ultimately, the pack was never finished, though I may post more resources for that at a later date.

This mod is effectively abandoned; I have no current plans to revive it. Some of the ideas would eventually end up in Tinkers' Complement however.
