Official Introduction Key Points

1. The power fantasy of an MMO, with the automation of an incremental game

3. Create 11 unique Classes, from Divine Knight to Bubonic Conjuror
4. IdleOn lets you create 11 characters, so you’ll have one of each class - each one plays a unique role in your account! Just don’t forget about the secret class-line, including a secret Subclass, secret Elite-class, and secret Mastercl… I’ve already said too much…
5. Unique gameplay with non-fighting mechanics
6. You’ll do more than just fight - in your quest toward the endgame, you’ll need to attain full mastery over skills like Cooking, Woodcutting, Alchemy, Construction, and MUCH more!
