The enchantment on the imcando pickaxe is kinda useless. Yes, it gives 20% bonus exp, but if it only lasts 100 charges, and you have to collect more imcando pieces to recharge it, then it's only good if you are using the lava flow mine, which would be silly if you have the levels to get the pick in the first place. Also wish I could keep my particle effect in the uncharged version, looks better that way, but it's a pain to keep it charged.
