How do I combine Fire and Soul in Doodle God?

In Doodle God, combining Fire and Soul does not directly create a new element. Instead, you need to follow a series of steps to unlock the necessary elements for progression. First, ensure you have both Fire and Soul unlocked. Fire is one of the four basic elements (along with Air, Water, and Earth), while Soul is created by combining Life and Death. Once you have both Fire and Soul, you can use them in further combinations. For example, Fire and Soul can be combined with other elements to create more advanced items. A useful combination is Fire + Soul + Energy, which creates Demon. This is part of the game's progression, where you experiment with different element pairings to unlock new categories and advance through the game. Always try combining newly unlocked elements with existing ones to discover more complex recipes. If you get stuck, revisit earlier elements or try thematic connections, as the game often rewards logical thinking.
