In the age of Universal Awakening on the Azure Sphere, a myriad of races and gods coexist. 
Devils, dark gods, and monsters descend upon the mortal realm, only to be met by the Awakened.
Howard, during his Awakening Ritual, discovers dual talents— F-rank Mana Recovery, and the supreme talent: Supreme Synthesis. 
He keeps a low profile, hiding as a 'common magus.'
Through countless acts of synthesis, he forges supreme artifacts, supreme skills, and supreme classes! 
Fireball synthesis... Ding! Synthesis successful, attaining D-rank skill— Fire Serpent! 
Fire Serpent synthesis... Ding! Synthesis successful, attaining B-rank skill— Fire Python! 
Fire Python synthesis... Ding! Synthesis successful, attaining S-rank skill— Dragonfire!
When devils invade and dark gods descend, they are left slack-jawed by the Azure Sphere before them. 
"No, this is a trap... a trap disguised as a mere cupcake!"

Talent Awakening: I, the Weakest Awakened, Start with Dragonfire Spell

Initiating a mana collapse is not complex; any magus can achieve it by simply letting go of their mental and physical restraints, turning their body into a vessel for rampant mana.

Then, uncontrollable mana would flood into the magus's body, transforming it into a bomb.

The instability caused by a mana collapse is sufficient to kill any magus of the same level.

This is the last resort for any magus, choosing to self-destruct to take their enemy down with them.

The brilliant silver light at the bottom of Howard's eyes grew more intense, gradually mingling with faint golden hues.

This was a sign that the body's mana capacity was nearing its limit.

Once the quantity of mana inside exceeds the body's mana capacity, mana would irreversibly flood into Howard's body like a breached dam, turning him into a bomb filled with mana within seconds.

Its power was enough to level everything within a ten-meter radius.
