What elements combine to form Book in Doodle God?

To create the Book element in Doodle God, you need to combine two specific elements: Paper and Knowledge. HereÔÇÖs how you can achieve this step by step. First, you need to unlock the Paper element. Paper is created by combining Reeds and Tools. Reeds can be found in the Nature category, and Tools are in the Technology category. Once you have Paper, you need the Knowledge element. Knowledge is created by combining Human and Philosophy. Human is a basic element in the Life category, and Philosophy is made by combining Human and Idea. Idea itself is created by combining Human and Light. After you have both Paper and Knowledge, simply combine them to create the Book element. This combination is logical, as books are made of paper and contain knowledge. Experimenting with these combinations will help you progress in the game and unlock more elements. Remember to revisit earlier elements as you unlock new ones, as they may combine in unexpected ways.
