NotesEdit
- Bag space upgrades can instead be purchased with Crowns in the Crown Store. This does not affect the cost per upgrade at a Pack Merchant; increasing to 100 slots will cost 11,000 gold regardless of whether the preceding three upgrades were bought at a Pack Merchant or in the Crown Store. Thus it's better to purchase the lower level bag upgrades with in-game gold and save your Crowns for the later ones, rather than the reverse.
- Since Update 17, you can now receive one free bag upgrade upon reaching level 12 via the Level Up Advisor, but only if you have not already purchased any. It is thus better to wait until after level 12 to start upgrading it, though this will only save you 400 .
