When should I upgrade my castle to lvl 2? I have the money for it now but I'm thinking I should sell my war avaries for coe's. Help please
Reason 1: U should upgrade ur castle to unlock Alchemist/to use mithrils Reason 2: Value for money. For 4 bil, u get both attack and spy stat increase which is almost worth 2 coes and 2 SoS.
