Acorn's New Form?

-----

The icy wall Nieve erected using Acorn's divine power was strong enough to resist the phantasmal flames, but it was already melting down at a rapid pace!

"RAAAHHH!"

The spectral monstrosity continued unleashing the same attack, rapidly beginning to wear down the walls as its entire body started growing larger.

There were small phantasmal things constantly flowing towards him from every place in the battlefield, making its entire body inflate like a balloon.

"Why is it growing larger?!" Nieve wondered, noticing it right away as she tried to keep the wall stable and strong. "This doesn't make any sense… Are Undead Chimeras this strong?"

Acorn's eyes widened, immediately realizing what was happening after noticing the obvious things.

"I-I think it's absorbing the souls of the other undead that had been defeated to boost its growth!" Acorn said. "W-Wait a second… that's it! I have a crazy idea… Nieve, please freeze my soul!"
