Shadiaz

This is Shadiaz, the next enemy that you may face after Chromaz. It's most recommended that you defeat Chromaz, as he drops important stuff for this battle.

Preparation
Make sure you have all your buffs equipped, along with your armor. When he spawns, purple lightning strikes around him. So you have to run so you don't get struck down. After it's over, make sure you start running, because his first move is lunging at you and trying to attack. Once THAT'S over, you will proceed the fight like normal.
