How do I combine Knowledge and Building in Doodle God?

To combine Knowledge and Building in Doodle God, you need to follow a specific sequence of steps to create the desired element. First, ensure you have both the Knowledge and Building elements unlocked. Knowledge is typically created by combining Human and Fire, while Building is made by combining Tool and Stone. Once you have both elements, simply drag and drop Knowledge onto Building in the game interface. This combination will create the element "Library," which represents a place where knowledge is stored and shared.

This combination is part of the game's progression, where logical connections between elements lead to new discoveries. If you don't have Knowledge or Building yet, work backward to unlock them by experimenting with other basic elements. For example, to get Tool, combine Metal and Human. For Stone, combine Lava and Air. For Metal, combine Fire and Stone. For Lava, combine Fire and Earth. For Human, combine Life and Clay. For Clay, combine Earth and Water.

By following these steps and experimenting with logical pairings, you can unlock the Library and continue progressing through the game. Remember to revisit earlier elements as you unlock new ones, as they may combine in unexpected ways to create advanced items.
