Chain Manager
Chaining your guardian's skills are crucial to big damage and team cohesion. However, not all guardians chain that very well into other guardians you actually want in your group. So that being said, I thought it would be a good idea to have a little sandbox area in which you can optimize chains and see which guardians are easier to chain with.
