The temporary cabin was indeed too simple, and without lingering there, Roger's mind stirred and he once again appeared in the Mist Hut.
He carefully examined the changes to his body, finding that his height had increased slightly, now likely nearing 6 feet 1 inch.
Moreover, the proportions of his skeleton had been completely altered. To tell the truth, Roger's previous body had many genetic defects, not in terms of deformity, but rather incompatibilities with practicing swordsmanship.
These defects could impact muscle strength and improvements during swordsmanship training.
Following the Green Grass Trial, the proportional flaws vanished completely; his current body was tailor-made for swordsmanship.
The color of his hair did not mutate into white like Geralt's, but whenever Roger concentrated or activated Hunter Vision, his pupils would turn into eerie vertical slits, glowing with a yellow sheen.
