Occasionally your party might not care for you or bluntly tells you that they could be off better somewhere else. This is easy to change. Each item that has "Gift" beside it can be given to a party member to increase their approval. For example, some of the demon things that you get in your travels (like the totem or demon statue) can be given to Sten. You will get at least a 5+ approval. Each item varies from person to person and some will yield more approval when given to a specific character. You must learn which item fits what person.
How you talk to a character can determine approval ratings. Some are minor changes, but still will be closer to the liking side or disgusted side however you so choose. The hardest two that you can speak to are Sten and Morhgan, but usually the correct words can lead to a loving moment and others to a long argument or a discussion, especially for learning about them. That is what takes the longest time. The only one you really never have to worry about is the Mabari of the group, or the dog in most cases. It will love you no matter what and will stay loyal forever. Give it a treat for being such a good loyal character!
