Actually Additions is in Alpha Pixelcraft, and will most likely be carried into Beta and beyond, so that is useful
Since Actually Additions is in Pixelcraft 1.12, emeralds and that 16-wheat-for-an-emerald trade is actually useful
Actually Additions allows you to use atomic reconstruction to make ascended emeralds, which can make the most powerful equipment in the mod and the modpack at its current state. The sword does 10 Damage, and the armor is a bit more powerful than diamond
I'm working on a new modpack called "Pixelcraft 1.11", but it will be a while before it is released
