+ Modify your item's attributes!(EXPERIMENTAL!) You can use a new command
(/lar mod or /lar modify) to set the durability like earlier
(/lar mod durability <amount>) or attribute
(/lar mod attribute <attribute> <value> <slot>) to your item
Example: /lar mod attribute attackDamage 10 mainhand
You can currently only apply 1 attribute to your item. Setting another one will remove the previous one. Still experimental, guys And yes you will get errors if you don't do it properly and no there's no feedback message
