Introduction

On this page, you will find Arcane-Mage-specific information to deal with each boss in the Sepulcher of the First Ones raid. This page assumes you already have a basic understanding of the fights, and focused primarily on how to do the fights as a Arcane-Mage specifically.

Disclaimer: Sepulcher of the First Ones is unique among raids in that three of its encounters were never available for testing. This, along with some of its others being changed substantially between their time on the public test realm and a live environment, means that many of the tips for these bosses will be changed over time.

If you have 4-set, you should use Arcane Echo Icon Arcane Echo if you are struggling with the p3 DPS check, otherwise use Resonance Icon Resonance.

3.1.

Tips

3.1.1.

Phase 1

Mages are very good at picking up the bombs and bringing them to the boss. Use Alter Time Icon Alter Time before activating Shimmer Icon Shimmer to get to the bombs that are far away. Then get back closer to the boss by re-activating Alter Time.

DPS-wise, there is not too much to optimise. Just make sure that you activate your burst combo on high health mobs to ensure they do not die before your burst is over, and ensure that you are hitting multiple targets with Arcane Barrage Icon Arcane Barrage and Arcane Orb Icon Arcane Orb.

3.1.2.

Phase 2

You can use Alter Time Icon Alter Time if you are targeted by Matter Dissolution Icon Matter Dissolution before using Shimmer Icon Shimmer (or Blink Icon Blink) to move out and re-activating it after getting hit to move back into position.

3.1.3.

Phase 3

Ensure that all your dps cooldowns are ready before phase 3 begins.

For more information, please refer to our Vigilant Guardian guide.

Skolex, the Insatiable Ravener

We advise you to use the following talents against Skolex, the Insatiable Ravener.

We advise you to use the following Legendary against Skolex, the Insatiable Ravener: Arcane Harmony Icon Arcane Harmony.

The Level 35 talent row is either Resonance Icon Resonance or Arcane Echo Icon Arcane Echo. Which one you pick depends on whether or not you have the Arcane Lucidity Icon Arcane Mage 4-Piece bonus. If you have 4-set, you use Arcane Echo Icon Arcane Echo, otherwise use Resonance Icon Resonance.

4.1.

Tips

If you are assigned to be one of the furthest people away from the boss, make sure you use your defensive cooldowns properly to minimise damage you take, as you will be taking more damage than the rest of the raid. A typical scenario would be to activate Alter Time Icon Alter Time on full health, waiting until you drop low, and then re-activating it or waiting for it to time out. After that, use defensives like normal to reduce damage taken.

Make sure to not be within 20 yards of the boss to avoid unnecesary movement.

Keep an eye on your boss mod timer for the boss' frontal cone (Retch Icon Retch) on a raid member, and ensure you do not activate your DPS cooldowns right before it goes out to avoid losing uptime on your cooldowns.

For more information, please refer to our Skolex, the Insatiable Ravener guide.

13.

The Jailer

We advise you to use the following talents against The Jailer.

We advise you to use the following Legendary against The Jailer: Arcane Harmony Icon Arcane Harmony.

13.1.

Tips

This fight has various different types of knockbacks at many different intervals. Additionally, you also need to jump into holes in the floor which will knock you up. All of these mechanics can be circumvented with the use of Alter Time Icon Alter Time. This can be done by activating Alter Time before the knockback goes out, or before jumping into the hole in the floor, and then immediately re-activating it when the knockback/up animation has started. Additionally, the knockbacks can also be negated by using Shimmer Icon Shimmer after the animation started, but make sure to wait a short time before activating it as otherwise you risk still getting knocked back.

13.1.1.

Phase 1

Make sure you watch the timer for Torment Icon Torment, and be already properly spread from other people before it goes out if it lines up with Rune of Power Icon Rune of Power or Arcane Power Icon Arcane Power, to ensure you do not have to move out of your Rune while spreading for torment. Additionally, watch for the timer of Relentless Domination Icon Relentless Domination to ensure you do not have to hide behind a pillar in the middle of your DPS cooldowns.

13.1.2.

Phase 2

Make sure you watch the timer of Rune of Compulsion Icon Rune of Compulsion, try to line up Touch of the Magi Icon Touch of the Magi so the explosion hits as the Rune of Compulsion goes out. Only delay Touch of the Magi up to 10 seconds or so to enable this, otherwise just use it like normal. Additionally, make sure to line up your Arcane Barrage Icon Arcane Barrage casts so that you use it when it can hit multiple enemies to benefit from Resonance Icon Resonance and get additional cleave damage.

13.1.3.

Phase 3

Assuming your group is allowing the adds from Torment Icon Torment to get stacked up (via Knockbacks / Grips etc), you try to line up your Touch of the Magi Icon Touch of the Magi to explode Touch of the Magi onto them. Additionally, make sure you use Arcane Barrage Icon Arcane Barrage so it lines up with the adds as well to benefit from Resonance Icon Resonance and get additional cleave damage.

If you get targeted by Rune of Domination Icon Rune of Domination, you can use Ice Block Icon Ice Block to get rid of the debuff.

For more information, please refer to our The Jailer guide.
