Cold Immunity

  "Although you finished this part of the mission rather fast, I believe I obtained suitable rewards," Isis said. "Considering that you are going to face Poseidon eventually, these skills will help you more than a little bit."

Cold Immunity Tome

Effect: It decreases the damage caused to you by ice-related attacks by ten points per level.

Freezing Aura Tome

Effect: It decreases the damage caused on you by an ice-related attack by ten points per level. It increases all of your ice-related attack damage by three percent per level.

"What do you think?" Isis asked.

"What I think, you ask…" Ryan frowned.

  To be honest, Ryan had no idea if those rewards were suitable enough. Again, he never found an enemy that had Cold Immunity… probably. While both skills seemed like some good cards to have against the god of the seas, Ryan still couldn't say if they were enough… even though the job had been relatively easy.
