  "pools": [
    {
      "rolls": 1,
      "entries": [
        {
          "type": "item",
          "name": "minecraft:diamond_chestplate",
          "weight": 1,
          "functions": [
            {
              "function": "specific_enchants",
              "enchants": [
                {
                  "id": "thorns",
                  "level": 10
                }
