Heat Sink (3.5e Invocation)

You duplicate the effects of pyrotechnics.

Alternatively, you can use it to render up to a 10 ft. cube/level of space incapable of combusting or maintaining a flame, draining away the heat required for it. Temperatures in the area never rise above 100 degrees, and all long-term combustion fails. Instantaneous effects, such as a fireball, are not affected. Any fires currently in progress are extinguished for for 1 round/level. If conditions remain where the substances would ignite again, they may do so once the duration is up.
