For a near-complete list of Formulas, see List of Formulas.
A formula is a mixture of 2 non-final elements that will create another element. Sometimes though, formulas can create 2 elements. e.g (Air) + (Pressure) = (Wind) & (Atomsphere) Some formulas are not allowed on the regular version, while on Pokki, it is allowed. On Pokki, they create exclusive elements. An example of a formula is (Water) + (Fire) = (Steam)
