Tournament World Type - Restricted Store:
On these game worlds the offer in the Store is limited to items which have no effect on your gameplay. This means you will be able to purchase some furniture for your house but no consumables or boosts for example.
Regular Tournament World:
On these game worlds the Store offers the same products like every other game world. This means you can also purchase potions, runes and other goodies that improve your gameplay.
Use XP Boosts!
