The Coinbound System lets him buy spells, skills, and stat boosts like a magical vending machine...But nothing comes free.Every fireball costs gold.Every body enhancement? Taxed.Even getting a suggestion comes with a convenience fee.While nobles train for years to master a single flame spell, he can just buy it off the System. From summoning spirit beasts to crafting forbidden runes, his power grows with every coin he scrapes together… and every unnecessary expense he dodges.But in a world where magic is passed down through noble bloodlines and ancient family grimoires, a broke outsider with a price tag on every spell has no business rising through the ranks.Still, he’s surviving. Thriving, even.So long as he tracks every copper and refuses to overspend on fireballs, he just might make it out alive.They call him cheap.They call him stingy.But one day… they’ll all remember the name:The Frugal Mage.

Felix's life on Earth had become a series of dead-end jobs, ruined relationships, and rotating apartments smaller than most postage stamps. By all accounts, even his own, he was a coward. Too afraid to move forward, to take risks. Yet when given the chance to choose between risking his life or walking away from a deadly encounter, he didn't hesitate.Moments before his untimely demise, Felix was snatched from earth and thrust into a magical world known only as ‘The Continent’. Empowered by the ‘System,' he learns that he can strengthen himself through combat and dedication. To survive he'll have to push himself beyond his limits, or else fall to the monsters all around him.Levels, stats, and magic. Death is the start of a terrible fate, but if he lives…who knows what he will become.
