- "Create a warm air current with fire energy."
- "This fire-based Psynergy creates a warm updraft strong enough to lift the user up to otherwise inaccessible heights."
 Basic Description
Thermal is known inherently by Eoleo and costs 3 PP per use. Thermal is used at blocks that emit a spiraling column of fire to updraft which can then be stood upon to ride up to the floor above. Once at the top, the updraft can be used as a makeshift platform for navigation. However, the updraft will cease once the player leaves the room.
The first time the party encounters one of these fire columns, a short cutscene commences, showing Eoleo using the Psynergy and giving an explanation of its use.
