Introduction

Below, you can find class and spec-specific advice for every fight in Liberation of Undermine. If you are looking for a general overview of the Raid that is not spec-specific, check out our dedicated Liberation of Undermine Boss guides.

On this page, you will find tips and tricks specifically tailored toward Fire Mages and its toolkit based on the recommended talent build. It does not include general tips for mechanics, which are included in the full raid guide instead, whereas this page assumes that you are already familiar with most of the major mechanics of each encounter.

All recommendations are progression-based tips and will not necessarily be the best for an overall DPS ranking.

Tips for Vexie Fullthrottle for Fire Mage

2.1.

Defensive Tips

  • Activating Alter Time Icon Alter Time right as Exhaust Fumes Icon Exhaust Fumes goes out and then re-activating it near the end is a great way to avoid all of the damage and minimize healing required on you.
  • Make sure to use Blazing Barrier Icon Blazing Barrier if you get targeted for Incendiary Fire Icon Incendiary Fire.
  • Otherwise simply rotate using your defensives during the bonus damage phase to minimize the healing you need.
2.2.

Cooldown Usage

  • Use your cooldowns right at the start of the fight, and then 1 Combustion Icon Combustion in-between each bonus damage phase, and delaying every second for each bonus damage phase.
2.3.

Mechanical Tips

  • Use Alter Time Icon Alter Time if you get Spew Oil Icon Spew Oil, after which you can use Shimmer Icon Shimmer to drop the oil, and then re-activate Alter Time.

Tips for Cauldron of Carnage for Fire Mage

2.6.

Defensive Tips

  • While on the Flarendo side, you should rotate your cooldowns for each Scrapbomb Icon Scrapbomb. Ice Cold Icon Ice Cold for one, Greater Invisibility Icon Greater Invisibility for the second and Blazing Barrier Icon Blazing Barrier + Mirror Image Icon Mirror Image for the third.
2.7.

Cooldown Usage

  • Generally you can use your DPS cooldowns as they become available. However, keep an eye out of the boss energy bar. If it is close to full, you should hold your cooldowns a few seconds to align it with the intermission to get cleave damage out of your cooldowns. This will align pretty well naturally, only having to delay cooldowns a few seconds. Since Combustion Icon Combustion has such a short cooldown with all of its cooldown reducing effects, make sure you do not delay it more than a few second.
2.8.

Mechanical Tips

  • This is a relatively straightforward boss from a mechanical standpoint. Make sure to use Shimmer Icon Shimmer aggressively to avoid losing uptime when dealing with the mechanics.
2.9.

Mythic Difficulty

Best Talents

If your group requires it, you can spec out of Ice Cold Icon Ice Cold to be able to solo soak Scrapbomb Icon Scrapbomb.

Tips for Rik Reverb for Fire Mage

2.11.

Defensive Tips

  • If targeted by Sound Cannon Icon Sound Cannon, make sure to use a defensive like Mirror Image Icon Mirror Image + Blazing Barrier Icon Blazing Barrier.
2.12.

Cooldown Usage

  • Use Combustion Icon Combustion as it becomes available, unless the intermission is about to come up, then hold on to it for after the intermission as to not waste it.
2.13.

Mechanical Tips

  • During the intermission, if you cannot make it to an Amplifier in time for the shockwave, or if you are doing other things (like channeling a different Amplifier), you can use Shimmer Icon Shimmer or Alter Time Icon Alter Time to safely make it through the shockwave. Shimmer can be used to simply go through it. If using Alter Time, you have to place down Alter Time and then move away from your Alter Time, and then re-activate it after the shockwave moved over your snapback position.

Tips for Stix Bunkjunker for Fire Mage

2.16.

Defensive Tips

  • Use one of your defensives if targeted by Incinerator Icon Incinerator.
  • There are no real hard hitting specific mechanics on this fight (assuming the mechanics are done properly) to activate specific defensives for, so I recommend simply rotating your defensives whenever the rot damage starts being high (Toxic Fumes Icon Toxic Fumes) or your healers are struggling.
2.17.

Cooldown Usage

  • You will want to align Combustion Icon Combustion with when the adds are rolled into the boss and take bonus damage. When this happens depends on your strategy and how effective the players in the raid who are doing the garbage rolling are at the rolling. Generally, due to how often you get Combustion, you should not be delaying Combustion more than a few seconds for this.
2.18.

Mechanical Tips

  • Make sure to use Counterspell Icon Counterspell on Scrap Rockets Icon Scrap Rockets (from the Scrapmasters).

Tips for Sprocketmonger Lockenstock for Fire Mage

2.21.

Defensive Tips

  • Rotate defensives on Unstable Explosion Icon Unstable Explosions (the explosion after a Foot-Blaster is soaked). Generally a single minor defensive like Blazing Barrier Icon Blazing Barrier or Mirror Image Icon Mirror Image will do, but if it overlaps with Sonic Ba-Boom Icon Sonic Ba-Boom, make sure to use either Greater Invisibility Icon Greater Invisibility or Ice Cold Icon Ice Cold.
  • If you are soaking rockets from Rocket Barrage Icon Rocket Barrage, make sure to always have up either Blazing Barrier Icon Blazing Barrier or some other defensive. It is not worth using Ice Cold Icon Ice Cold on this unless you absolutely have to soak it and you are low health, as you should keep it for nasty overlaps of mechanics like described above.
  • If you are soaking a Foot-Blaster, activate Alter Time Icon Alter Time right before moving out of the group to the one you will soak, but then after soaking it, do not immediately re-active it. Instead, wait a few seconds until the damage over time effect is (almost) gone before re-activating.
2.22.

Cooldown Usage

  • Use everything on cooldown.
2.23.

Mechanical Tips

  • To minimize damage loss, make sure to use Shimmer Icon Shimmer during Mega Magnetize Icon Mega Magnetize to move away from the pull in.
  • Activate Alter Time Icon Alter Time right before the boss reaches 100 energy and casts Beta Launch Icon Beta Launch, then re-activate it immediately after the boss pulled you away.

Tips for One-Armed Bandit for Fire Mage

2.26.

Defensive Tips

  • Activating Alter Time Icon Alter Time before Foul Exhaust Icon Foul Exhaust starts doing damage, will allow you to still heal yourself back to full health by re-activating it even through the heal absorb. If your healers have properly assigned raid cooldowns this is most likely not needed and just a waste of Alter Time (since healers must still fully heal through your absorb to get rid of it), but it is good to keep in mind in more chaotic runs like pick up groups to keep yourself alive.
  • For the Flame and Coin Token effect of Reward: Flame and Coin Icon Reward: Flame and Coin, make sure to cycle defensives. Greater Invisibility Icon Greater Invisibility only lasts about half the effects, so use it after a few seconds and not right at the start. Ice Cold Icon Ice Cold lasts the entire duration so is a great defensive to use for it.
2.27.

Cooldown Usage

  • Use on cooldown. If the adds are about to spawn, you can delay a few seconds if needed, but generally you should use on cooldown and only delay a few seconds at most.
2.28.

Mechanical Tips

  • Make sure to use Counterspell Icon Counterspell on the Overload! Icon Overload! casts from the assistants.
  • If the Shock and Coin Tokens are inserted and the boss casts Reward: Coin and Shock Icon Reward: Coin and Shock, you can activate Alter Time Icon Alter Time while far away from the pull in effect and then re-active it when you get close.

Tips for Mug'Zee for Fire Mage

2.31.

Defensive Tips

  • During phase 1, the Zee phase is generally higher damage taken, so try to save most of your defensives for this part of phase 1.
  • You can soak multiple overlapping circles dropped by soaked mines by using either Ice Cold Icon Ice Cold or Greater Invisibility Icon Greater Invisibility.
2.32.

Cooldown Usage

  • Timings vary greatly on this fight due to the different available strategies, where you can move to the different sides at multiple different timers, and depending on which side you start on. Luckily, you will basically always have multiple Combustion Icon Combustions available for each phase.
  • Make sure to hold Combustion Icon Combustion so that it is available when the boss reaches 40% health.
2.33.

Mechanical Tips

  • If you get targeted by Frostshatter Spear Icon Frostshatter Spear, you can get into position through the slippery effect easily via Shimmer Icon Shimmer.
  • You can soak the Zee phase mines effectively by activating Alter Time Icon Alter Time right before walking into them and then immediately re-activating it after hitting the mine. It will cancel the falling and heal you to full. You can then follow it up by a minor defensive like Blazing Barrier Icon Blazing Barrier and soak the fire circle it leaves behind, or a bigger defensive like Greater Invisibility Icon Greater Invisibility and soak multiple overlapping circles.
  • During the intermission, after the white arrow soak (Storming Impact Icon Storming Impact) the boss goes into its rotating mechanic (Bulletstorm Icon Bulletstorm). During this, you can minimize movement by using Shimmer Icon Shimmer to move through the Bulletstorm. However, this can be a bit risky as the Bulletstorm is quite big, so a safer approach if you do not feel comfortable doing this, is to activate Alter Time Icon Alter Time, then Shimmer away alongside the way the boss is rotating, and then re-activate Alter Time after the Bulletstorm has passed your original Alter Time position.

General Defensive Usage Notes

Fire Mage has several defensive spells that you should plan to use and rotate throughout mechanics. You should opt to use the smaller cooldown spells often as needed with incoming mechanics and save bigger cooldowns like Ice Cold Icon Ice Cold for large incoming damage.

  • Blazing Barrier Icon Blazing Barrier
  • Mass Barrier Icon Mass Barrier
  • Alter Time Icon Alter Time, although technically does not reduce damage, it is an incredible tool to heal yourself to full health after a big hit
  • Mirror Image Icon Mirror Image
  • Greater Invisibility Icon Greater Invisibility
  • Ice Cold Icon Ice Cold / Ice Block Icon Ice Block
2.42.

General Damage Cooldown Usage

Fire Mage has a few cooldowns to think about using optimally on the fights in Nerub-ar Palace:

  • Combustion Icon Combustion — Our main damage cooldown. Although it is initially a 2 minute cooldown, in practice it is significantly less, closer to 45-60 seconds. This is due to many of our cooldown reducing mechanics like Kindling Icon Kindling, Unleashed Inferno Icon Unleashed Inferno, WoWMageFire111ClassSet2pc and Shifting Power Icon Shifting Power. Since the cooldown is a bit dynamic, perfectly planning all of its usages throughout a fight is generally not recommended as a streak of bad or good luck can change the timings. Due to this, you should generally use it as soon as it becomes available to get extra usages out of it, and only delaying a few seconds at most for important mechanics.

In addition to the general rotation, you want to keep in mind that your goal is to use your cooldowns as often as possible during an encounter. With that in mind, your secondary goal is to use them at the correct time.
