The Prawn Suit Thermal Reactor is an upgrade for the Prawn Suit that generates power in areas that are 30°C or higher.
Its main use is for exploring biomes like the Inactive Lava Zone and Lava Lakes because of the high temperatures in the aforementioned biomes, but it is also possible to use geysers or thermal vents in cold and deep biomes like the Lost River, Underwater Islands or Deep Grand Reef for quick recharges to enable extensive trips.
