I am a level 55 hero, and my spirit animal is a penguin. My advice for gamers:
-Get as much cash as you can, it will definitely be worth it in the future.
-Don't go on cavern quests if you are under level 10. They are very dificult.
-Use the book codes. They work even if they are used on different scholastic accounts.
-ONLY use greenheart tokens on the 2x exp. boost.
-Go on heroic quests. It promises you better rewards, with more exp, and gold.
-Play multiplayer. You can get some rare items there, as well as expirience every round.
-Like I said, don't use greenheart tokens on anything but the 2x exp boost.
-I wouldn't nessecarily buy your gear from Mustela. Get it on your questing.
LAST OF ALL, PLAY TO WIN, BUT IF YOU FAIL (hint hint) YOU GET A MEDAL SO IT ALL WORKS OUT THE SAME!
