Immortals of Aveum

Complete chapter 2. This is part of the story and is unmissable.

Slight spoilers ahead so beware

This is the games tutorial. You will learn how to use red, green, and blue magic. You will also gain lash, shield and shred. After fighting some basic enemies as part of your training, you'll have a boss fight which is fairly easy, on normal at least anyway.

I kept on the move and used shatter magic (blue) mostly. The blue shred is effective ( + ). If he gets close use Blastwave (red). Use of shield is also recommended (). Defeat the boss and complete the mission, the achievement pops after the cutscenes
