From Shadows, I Devour All - Episode 10

After a skirmish shows a Level 1 Qyren beastling can down a Level 3 Aegishorn, a living bloodbound beast absorbs blood essence (+1003) while a person helps. Using a mindstone, it takes unclaimed willpower to speed cultivation and enable a second summon. Evolution completes and the beast learns Razor Rip, an attack that ignores defense. Sensors flag more high-purity willpower; the beast absorbs it, getting a major boost and briefly assuming a human form. Energy swelling changes its capabilities — then an unexpected voice greets the transformed creature: "Well, hello there."
