Upgrade or alternative upgrade?

And it’s even easier to quickly build a warehouse and not sacrifice anyone, while the Druids take care of the enemies with their melee attacks, and the Mages with their bears (it’s dangerous to only use melee attackers against Mages, they can be defeated with Magic Bolt). Of course, it’s desirable to build a guild up to level 2 as quickly as possible and recruit upgraded Northern Riders.
