This version adds the following enchants:
Frost Bolt - a crossbow enchant that, upon hitting a target, freezes them (like freezing an entity in powdered snow) for 200 ticks/10 seconds, reducing their movement speed and dealing a bit of damage. Cannot be combined with Quick Charge.
Updraft - a shovel enchant that, upon hitting a target whilst they're in mid-air, launches them up even further (about 5 blocks). This is pretty useful for combos.
