What do you do with stars on Free Realms?

Answer 1

Stars help you level up. The more stars you get the faster you level up. In combat classes you can add the stars to a skill. This will 'level up' the skill and give it more 'power'. In order to do this hit 'c' then click the star at the bottom of your screen.

Answer 2

You don't. It is used for a collection.
