How about adding the original magic items? Make them do something in the game!
Some ideas:
- Catapult: shows up in game and provides XP. operated by 8 mabu
- dragonfire cannon: shows up in game and cuts time of troll camp attacks
- healing elixer: shows up as a "healing clinic" and provides extra XP for sheep mob missions
- pirate ship: appears docked like Flynns ship and unlocks some missions to the "pirate seas"
- empire of ice: a building that houses 600 mabu
- anvil: extra XP from blacksmith shops
