Knowledge is an important way to gain more CP in Black Desert Mobile. You can gain Knowledge from different activities, such as meeting people, completing quests, defeating important bosses, or killing a certain number of specific mobs. To avoid having to return to every town you’ve ever been to once you hit level 55 and want to boost your CP with Knowledge, you should always check the list of important people in an area before you leave. Any person in this list that has a little book displayed by their name will give you a bit of Knowledge if you talk to them.

Hope this helps :)
