Item modification

Item modification is a startup event.

ItemEvents.modification is a startup script event used to modify various properties of existing items.

ItemEvents.modification(event => {
  event.modify('minecraft:ender_pearl', item => {
    item.maxStackSize = 64
    item.fireResistant = true
    item.rarity = "UNCOMMON"
  })
  event.modify('minecraft:ancient_debris', item => {
    item.rarity = "RARE"
    item.burnTime = 16000
  })
  event.modify('minecraft:turtle_helmet', item => {
    item.rarity = "EPIC"
    item.maxDamage = 481
    item.craftingRemainder = Item.of('minecraft:scute').item
  })
})
