Inferno

Inferno is a Sonic Device created by Toothless Haddock for Hiccup Haddock. The device is a hybrid between a flaming sword and a Sonic Screwdriver

Inferno has more limits then the Sonic Screwdriver, as it was not built by the TARDIS and thus does not have the same software as the Sonic Screwdriver.

It cannot work on wood, it doesn't work on anything deadlock, and it can easily spark and overload if asked to do too much at one time.

List of Functions

 * Calling the TARDIS
 * Shattering Death Song Amber
