Loot levels for swords

Each sword will have its own loot level. Loot level affects rare and equipment drops. it's something like this:

-wood sword: 1 loot level

-stone sword: 1,5 loot level

-iron sword: 2 loot level

-Diamond sword and Trident: 3 loot level

-Netherite sword: 4 loot level

-Golden sword: 5 loot level

1 loot level equals 1% extra chance of rare and equipment drops

loot level only affects are rare and equipment drops, it will not duplicate regular loot

Looting will increase loot level by 1 point per enchantment level.

However, I would like it to be added to encourage the player to improve their weaponry, to increase the difference between weapons, and especially to give value to the golden sword
