To start a dungeon, create a party from the /dungeons menu. You can do dungeons with a group of 1-5 players. To enter a dungeon, you need a corresponding dungeon key.
Dungeon keys can be obtained by finding 4 key fragments of the type. Defeating Alpha Pokemon and completing raids can reward you with key fragments.
Once you've started a dungeon, you can see all of the tasks on the side of your screen. Each dungeon has 4 tasks randomly selected. Dungeons can have defeating alpha Pokemon, collecting pokeLoots, defeating guardians, collecting stakes, finding gimmighoul, and Gem Collecting as tasks.
Once you complete all of the tasks, you'll be able to enter the boss room. Boss fights have 2 parts, complete both to finish the dungeon!
Certain chests are considered puzzle chests which give rarer loot. They can be found in puzzle rooms.
Poke Loots give better loot based on their tier.
There's a chance to get legendary Pokemon as dungeon bosses. The chances go up depending on dungeon streak. The player in the party with the highest streak is the streak that is used for the dungeon run.
There is a 1/30 chance of getting Zarude as a Grass Dungeon boss if you have a 15-20 steak.
Flags can be used to mark where you've been in the dungeon. The layout can be confusing. It's easy to forget where you've already been!
