Arid Heat as a utility Psynergy
Arid Heat is similar to Parch in that it is used to dry up water. Arid Heat can be used on small puddles to remove them. In particular, small basins of water will function as an "access point" for drying up a larger body of water so that the ground beneath it can be traversed. These basins can often be refilled by way of Douse to bring the water back.

Its encyclopedia entry reads as follows:
 * "This fire-based Psynergy can evaporate a water source in the blink of an eye."
