To take care your monster you'll need items. You can get items at any items shop or market. You'll also need food, weapons, and the safety of a well built house. Once you begin, you may only have a small hut that is not well built, a rugged, old house or just a plop of land with nothing on it. You must go to the wood shop and pay for them to build you a secure house. While they are building you a house you can stay at the town shelter for two days FREE!
You'll have to feed your monster when it is hungry. You must make sure that you always have enough food for your monster.
