A really badass form of Rosland! Drawn by  Taikoku
The character belongs to me of course, and is part of the Mortalis Et Bestia storyline.

First off, this was a pretty experimental idea. That idea being characters can sort of channel their magic to a point of it being supercharged, at the cost of it becoming near unstable. The elemental magic within them takes a form best suited for the user, in Rosland case looking a bit demonic, only because he's touched by Sin. To become corrupted, one would have entered a state of uncontrollable Sin. Whether it be a form of Lust, Greed, Gluttony, etc. And Rosland's sin happens to be Wrath.

When Rosland obtains this form, the scar across his stomach is quickly coated in magma, before the magma spreads across his body. Horns sprout from his head and down back, with the same magma lines crawling from base to tips. This form not only gradually depletes his magic pool, it also drains his physical health. But with the advantage of increases all other physical parameters like Strength, Speed, and Durability, why wouldn't he take the chance? The heat from his body dramatically increases to an undetermined temperature. And he can unleash the following abilities that will then depower him afterward;

Lvl 1 Aer Burst: Conflagration - A series of quick punches, kicks and slashes that guarantee the Burn status effect.
Lvl 2 Aer Burst: Inferno Core - Rosland creates a giant sphere of blazing glory, tossing it at the enemy before exploding to cause a wide area of Large fire damage.
Lvl 3 Aer Burst: Supernova - It's time to put fire to the ultimate test! Rosland takes hold of an enemy and unleashes a direct beam of heat, similar to a quasar, before the initial nova explosion for Massive fire damage. It leaves Rosland with 1hp remaining.

these are all inspired by Limit Breaks from Final Fantasy Series. Mystic Artes from Tales of Series, and specifically Break Soul mechanic from Tales of Berseria.
