Noon question, couldn't find it in FAQ

[Julio Rivera]

How do I change the gear I use in arenas and boss battles? I've changed them in the knights section but it doesn't change it in those two places. Thanks for the help!

[Kangaroeland]

Go to arena
Click.battle
On top left it should say "team order".

For raid:
Go to raid. Click on a boss and click fight. Instead of to battle click option on the left saying team order

For epic boss: once you unlock it go to the boss click fight and add the knights you want.

Hope this helps
