Skolas: Phase One
When you first enter the arena you may get the sudden urge to start unloading your gun right into Skolas’s face. When you shoot, you may notice that your gun does basically no damage (a fully upgraded Fatebringer was hitting for 4 damage with Arc Burn). That is because in this first phase Skolas is being protected by a special Servitor. At the very beginning of the fight, if you followed our directions about heading left immediately, you will encounter this servitor. Take him out and you’ll be granted about 30 seconds of damage dealing time.
Use these 30 seconds to dish out as much damage as you possibly can. That means get out your heavy weapons, go for critical head-shots, and be completely relentless. After this small window of opportunity Skolas will revert back to his virtually invincible self until you can find another of those special Servitors.
When Skolas cannot be damaged, shift all focus to the additional enemies for a bit. During this fight there will be more enemies than usual, and they can become a real headache if not taken care of quickly. The ones you really want to eliminate are the Captains and yellow-health Servitors since they will put serious pressure on you. Once you feel you’ve thinned out their ranks enough, hunt for the next special servitor and rain hell on Skolas once more.
After enough damage has been done to Skolas (approximately 1/3 of his health bar) the Servitor bonds will be completely broken and it will be open season on this terrifying Fallen commander. Unfortunately, that is also when the second phase kicks off, and staying alive will be even more important than it was before.
