Lava Release: Fountain of Ire

After completing the hand signs, the user of this technique raises their hands and pulls upon lava already in the area, shooting a spout of it into the sky. Alternatively they can shoot it out of their mouth by creating lava in it.

This lava will fall back from the sky in the form of rain, covering a fairly wide area in a torrent of lava droplets. This can either be used to force an opponent to block the technique, thereby keeping them still and open for additional attacks, or it can be used to cause mass destruction, as most places aren't that level of fireproof.

If the user chooses to use natural lava for this technique, it has the additional benefit of being mostly immune to chakra absorption, which has become increasingly common upon the battlefield. Even if you remove the chakra from the technique, one would still have to deal with the hail of lava droplets, as the only thing the chakra does is keep them hot on their trip down. By the time you get close enough to remove the chakra, they are already too close to your body to have time to cool down, meaning the damage will continue unabated.

Author's Note
Once I get my lava release character made, I'll add a user to this technique.
