Sylas was absolutely relentless in his pursuit of power. As he improved rapidly, he vaguely began to understand that it wasn't just a matter of <Madness Control> and his Wisdom. All things considered, his <Madness Control> wasn't even an FFF- Skill, and his Wisdom was only 122. Neither of these things was particularly groundbreaking.
The biggest reason for all of this was because of his Legendary Path.
His sensitivity to Genes, their movements, what influences they had on his body, and how his body integrated with them… that sixth sense of sorts had all come from his experiences with Extricate.
He had attempted a fusion with all of the Physical Genes several times more than he could even count, and it was in part due to these experiences that he had managed to improve <Madness Control> to Gold Mastery so quickly, allowing him to tap into Legendary Mastery with the help of his Madness Comprehension.
