All the upgrades for shovels
Will mine a 3x3x1 area, in the direction of the block face you're mining, just like the TC Excavator
With this upgrade, the block you mine will drop its block form, just like the PC enchantment. For example, breaking grass will drop grass and not dirt.
The shovel you're using will break less fast with these upgrades. The effect is stackable up to 3 upgrades. With 1 upgrade the shovel will last around twice as long as normal, with 2 upgrades it lasts 3 times longer and with 3 it lasts 4 times longer.
If carried in your inventory will repair 1 damage value per 10 seconds, or if you have 2 in your inventory 2 damage per 10 seconds This only works on the shovel you're currently holding in your hand.
