Item Damage

How to add or reduce damage on a tool or armor? It doesn't seem to work $item->setDamage($item->getDamage() + 2); is 2 less?

 

Try This, this will give item to player's inventory with 2 more damage, if you want to reduce it, then use - 2

PHP:

$item = Item::get(276, 0, 1);
$item->setDamage($item->getDamage() + 2);
$inventory = $player->getInventory()
$inventory->addItem($item);
