How do I combine Tree and Fire in Doodle God?

To combine Tree and Fire in Doodle God, you need to follow a specific sequence of steps. First, ensure you have both the Tree and Fire elements unlocked. If you don't have Fire yet, you can create it by combining Air and Energy. Once you have both Tree and Fire, simply drag one element onto the other in the game interface. When you combine Tree and Fire, the result will be Ash. This is a straightforward combination that follows the logical interaction of fire burning a tree, leaving behind ash.

This combination is part of the basic progression in the game, and unlocking Ash will help you move forward to discover more complex elements. If you are stuck, remember to experiment with other elements you have unlocked, as many combinations are based on real-world logic or thematic connections. Keep exploring and combining elements to progress further in the game.
