The new Realm of Shadows content is going to "introduce players to, and have them save, the sorcerer’s homeland." Sounds intriguing, right? Well what about new enemies and bosses? New loot, pets, and gear? New quests? Nah, I bet what you'll really be excited about is the level cap increase that takes each characters' max level from 31 to 36.
If the Realm of Shadows sounds like your kind of place, then either download Arcane Legends and check it out or update it if you've already got it on your iOS device. Simple as that!
