This is a fork of jp's excellent oresplus mod. It features emerald tools, including a hoe. If 3d_armor is present, then emerald armor will be available, including a shield.
If X-Decor is present, then you can enchant your emerald tools, and if both 3d_armor and X-Decor are present, then you can enchant the armor.
