Attributes

Attributes are stored in the AttributeModifiers field. For example:

{
  AttributeModifiers: [
    {
      AttributeName: "generic.maxHealth",
      Name: "Heavy Armor",
      Amount: 180,
      Operation: 0
    }
  ]
}

This kind of attribute would give a player 100 hearts instead of 10.
