NBT:

display:

    Name: "&aStrength"
    Lore:
    - "&2Applies Strength to nearby players."
    - "&2Increases melee damage by 130%"
    - "&7Fuel needed: Iron Ingots"
    - "&8[Click to Select the Effect]"

        UUIDMost: "1"
        Amount: "100"
        Name: Attack

The broken part is attribute section for sure, without it it’s all OK.

I finally came up with

AttributeModifiers:
  compound:
    AttributeNam­e: "generic.attackDamage"
    Name: "Nullify attack"
    Amount:
      double: 1000
    Operation:
      int: 0
    UUIDLe­ast:
      long: 10000
    UUIDMost:
      long: 10000

Which stopped internal errors.

But it didn’t do anything. I am not sure our server accepts those attributes, will need to do more tests.
