Step 1) Create Jett Characters filling your remaining character slots
Step 2) Skip the cut scenses
Step 3) Complete all the Quests including a gift for jet. You'll start off with 8 coins
Step 4) Log in every day on all of your characters including the Jett Characters.
Step 5) Enjoy your 46 coins on your Jett Characters. Varies for non-Jett Characters.
With this I'm going to have 51 scrolls. :)
