This Mod provides new tools called Blessing Emerald, yes, they are just tools that can be crafted from Emerald and are one level weaker than diamond, but the difference is that when Enchanted from the enchantment table, every enchantment level after enchantment will be multiplied by 2, which means it is twice as strong and more effective (if you feel it is too OP or ruins the experience, I have made a version that only multiplies by 1.5 or if you feel the durability is too high and causes the feeling of ruining the game, you can install the weak durability version so that you can use Emerald to fix it, at least Emerald will be less useless.
