Another really cool dragon designed and adopted from stephsadopts! : https://www.deviantart.com/stephsadopts

Igneous is a volcanic dragon that is able to control lightning and spit hot ashes, which can look like black flames. She is able to breath both lightning and hot ash together as well while in a sort of 'fury' mode (on the right).

She likes to collect gem stones and other shiny rocks that she finds around active volcanoes. She stores them in her pouch.

She's also able to withstand incredible heat, but is incredibly weak to the cold. While she's still able to be burned by lava/magma, she can take it a lot longer before showing any serious injuries.
