Setting Up

Raid buckets are an advanced feature designed for server owners to allow more control over what raids can spawn for a particular raid den and can be defined with a data pack. All fields in a bucket entry are optional. Note that if the biome field is empty, the bucket cannot be randomly assigned.

Setting up a raid bucket

{
  "include": {                        // you can filter by tiers/types/features/bosses
    "tier": [
      "TIER_ONE",
      "TIER_TWO",
      "TIER_THREE"
    ],
    "type": [
      "FIRE",
      "WATER",
      "GRASS"
    ],
    "feature": [
      "DEFAULT",
      "TERA"
    ],
    "boss": [                         // raids fill filter by tier AND type AND feature OR boss
      "cobblemonraiddens:pikachu"
    ]
  },
  "exclude": {                        // you can exclude certain tiers/types/features/bosses
    "boss": [
      "#cobblemonraiddens:starters"   // supports boss tags (needs to be defined)
    ]
  },
  "biome": [
    "*",                              // "wildcard" to include all biomes
    "#minecraft:is_overworld"         // supports biome tags
  ],
  "weight": 10.0                      // default weight of 10.0
}

Mechanics

Buckets only work if the raid den is in BUCKET cycle mode, which can be assigned either with the config or when spawned in with a command. The during resets, the raid den will choose from the bucketed filter of eligible raid bosses, instead of the full list. If no raid boss can be found for the bucket, it will then randomly select a raid boss from the total available.
