He immediately thought of himself. He had learned several spells through Inheritance Scrolls, including Arcane Imprint and Foul-Smelling Skin, and the spell he had made permanent happened to be among them. If he had been asked to learn the Miserly Spell in a short time as a First-Level Apprentice and make it permanent in a zero-ring spell slot, a rational assessment would have put his chances of success at virtually zero.
He had mastered that spell in Starry City, eating delicious fruit and basking in the sunlight of the dome's light stones, with potions to help him and an unhurried environment to work in.
The Little Fairy's choice was undoubtedly a mistake.
Yet as Ruger looked into its eyes, he suddenly hesitated. For some inexplicable reason, he wanted to give it a chance.
If there was any possibility of success, there was only one route to it, judging by Ruger's experience: an exceptionally high degree of compatibility.
Nothing else would do.
When he learned spells with which he had an exceptionally high compatibility, it felt as effortless as walking on level ground. Even among highly compatible spells, however, there were differences. If that compatibility reached the legendary theoretical limit, learning would become as simple as breathing, like a dragon learning to infuse its roar with tremors of mental power, or a Fire Spirit learning to breathe fire when it sneezed.
But such absolute compatibility remained purely theoretical. Ruger felt that even his compatibility with spells such as Foul-Smelling Skin and the Shedding Spell fell far short of that limit. His permanent one-ring spell, the Miserly Demonfall Spell, might have come close, since it had been born according to his own circumstances during the transformation of his advancement. Precisely because of that, however, there had been no learning process, and he
