1. Select Quest or Versus
Select a Quest or Versus battle. Make sure you read the Team Requirements!
2. Select Team Tab
You’ll see your current roster of Monsters available for the selected Quest.
3. Change Monsters
Tap on a Monster currently in your Team. A list of eligible Monsters will appear. You can switch the selected Monster with another one from this list.
Don't forget that some quests have specific requirements for the Monsters such as single-elements or certain elements only. If you do not have any Monsters on your Island that meet the requirements, then they will not appear in the list.
