Eld, Hilltop Manor in Dublin.
After parting with Amanda, Roger left Mist City and, undisturbed, began to prepare the Conversion Potion.
First, he took out the brilliantly lustrous Vampire fang, set it aside, and then extracted a portion of the Hart Spirit's Horn.
The solution made from Black Pine Branch, Aconite Herb, Silver Stone Dust, and Griffin Tailbone soaked the Hart Spirit's Horn.
The soaking liquid was placed in the center of the Array.
Within the yellow liquid, something wriggled like insects, gradually engulfing the Hart Spirit's Horn bit by bit. After soaking, the Hart Spirit's Horn was scorched with flame, and cracks appeared on the originally solid surface.
After completely disintegrating, it was ground into a green powder wrapped in a yellow glow.
Having done all this, Roger used a pre-prepared Valerian Solution to soften the Vampire fang.
