The stats of tools and armor will now depend on their current durability. As an item wears down, its effectiveness decreases.

For example, a Diamond Sword at full durability (1561) has standard stats: 7 damage, 1.6 attack speed, and other parameters. However, if its durability drops to 1000, its stats will also decrease—damage will drop to around 4.85 and attack speed to 0.98.

What changes depending on durability?
Damage
Attack speed
Kickback force on impact
Block breaking speed
Block interaction range
Entity interaction range
Defense value
Therefore, the lower the durability of an item, the weaker it becomes, making equipment wear more significant and affecting playstyle.
