the shovel enchantment is self explanatory; you shovel things upward. The vertical knockback should be enough to deal a little fall damage, and would also be used for escaping combat similarly to regular knockback on swords. Knockback on swords is often seen as a nuisance though, to where youd want a SEPARATE knockback sword, so this would then give your "spare shovel" a whole new use!

the pickaxe enchantment is inspired by the Combat Test Snapshot, where Pickaxes deal more durability damage to armored players; that wouldn't really work PvE though, so my suggestion is to just effectively "ignore" some armor on any target

Hi, thanks for the suggestion and cool mechanics! I will add them to the game as soon as I figure out the enchantment concept
