"I kind of liked the atmosphere that you created here," Femradiel said just before he decided to fire.
When Ryan fired, he saw the massive magma shield protecting the dungeon master concentrated in front of the monster. One very thick magma wall tried to stop Ryan's arrow, but much to everyone's surprise, the arrow pierced all that magma and hit the monster's chest. This time the projectile pierced the monster's body pretty deep, but the attack wasn't over yet.
All the mana Ryan had concentrated in the attack exploded, and the whole torso of the monster froze. That was the power of Cryomancy and Water Creation, but to essentially freeze the equivalent of a small mountain… Ryan was quite shocked with the result since he didn't use a single potion to power up his attributes.
