Underworld Tyrant Mode

Underworld Tyrant Mode (, Andāwārudo Tairanto Mōdo; lit. "Insatiable Rampage of the Demonic Overlord") is considered to be an alternative to the Diabolical Extremities and an equally powerful powerful ability formed from Devil Slayer Magic; it's considered to be the favored amongst the two.

Trivia

 * This was approved by Per.
 * This idea came up in chat some time back, proposed by the co-author Six, who needed a translation for one of his spells.
 * This is basically the equivalent of Primal Dragon Mode, having the same effects and drawbacks; in a sense, it's more of the alternative variant of Diabolical Extremities. In this case, the user won't suffer from the possibilities of turning into a Demon, but they will have a higher chance of losing their Devil Slayer Magic. To this extent, no user may have both Diabolical Extremities and Underworld Tyrant Mode; it's either one or the other, no excuses.
