Liberation of Undermine Boss Guides for Holy Priest
Liberation of Undermine Raid Builds, Tips, and Tricks for Holy Priest
Tips for Vexie Fullthrottle for Holy Priest
Defensive Tips
 Desperate Prayer or 
 Fade are best used when targeted by 
 Incendiary Fire.- Use both 
 Desperate Prayer and 
 Fade together if you get low from 
 Exhaust Fumes and
      need to stabilise your health. 
Cooldown Usage
 Apotheosis on the pull allows you to heal through the first couple of 
 Exhaust Fumes.- You should pair 
 Halo up with 
 Apotheosis and then aim to use 
 Halo shortly after it
      is off cooldown, so it is ready for the next 
 Apotheosis. 
 Apotheosis should be used at the start of the first 
 Backfire intermission, then each
      intermission afterwards.
 Divine Hymn can either be used to to cover damage from either 
 Exhaust Fumes if your raid
      falls behind, or for 
 Backfire during intermission as it is available.
Mechanical Tips
- You can use 
 Leap of Faith to quickly pull allies with low mobility from the 
 Oil Slick. 
 Guardian Spirit is good to coordinate with your tanks to help mitigate 
 Tank Buster damage.

Tips for Cauldron of Carnage for Holy Priest
Defensive Tips
 Blistering Spite and 
 Galvanized Spite are both stacking DoTs that are applied to players
      depending on where they are in the arena. These stacks will reset at the end of intermission when the bosses swap
      positions. You will want to save 
 Desperate Prayer and 
 Fade for the end of intermission, where the
      stacks will be highest.
Cooldown Usage
- Using 
 Apotheosis around 50 seconds into the encounter for the 3rd Scrapbomb / Thunderdrum Salvo
      combination will ensure it's also available for the second intermission. - Intermission deals heavy damage through 
 Colossal Clash from both bosses. This is the perfect time
      for 
 Apotheosis as it will be active for the entire intermission. 
 Divine Hymn can be used at the start of intermission 1, then again in intermission 3 to heal through
      
 Colossal Clash.- Spatial Paradox or Rescue from an Evoker are very helpful to ensure your 
 Divine Hymn or
      
 Symbol of Hope casts go off without being interrupted by forced movement. 
Mechanical Tips
 Guardian Spirit is good to coordinate with your tanks to help mitigate 
 Eruption Stomp damage.- You can use 
 Leap of Faith to help someone move into a bomb soak if they are out of position due to
      patches of fire. 
 Psychic Scream and 
 Holy Word: Chastise can both be used to help stop 
 Voltaic Image.

Tips for Rik Reverb for Holy Priest
Defensive Tips
- Use 
 Fade or 
 Desperate Prayer for either 
 Static Jolt or 
 Sound Cannon
      casts, or to stay healthy if you have to drain a pillar. 
Cooldown Usage
 Apotheosis should be used for the second 
 Sound Cannon at 1:15 then again around 4:15. If
      you take 
 Seraphic Crescendo you should aim to use 
 Divine Hymn at around 1:15, 3:45 then again at
      5:45.- You should pair 
 Halo up with 
 Apotheosis and then aim to use 
 Halo shortly after it
      is off cooldown, so it is ready for the next 
 Apotheosis. 
 Divine Hymn can be used for a 
 Static Jolt or 
 Sound Cannon that 
 Apotheosis is not available.- Be mindful that 
 Lightwell will despawn if you go too far away from it, and try to place it in the
      middle of where you will be soaking pillars during phase 2. 
Mechanical Tips
- Keep your 
 Angelic Feathers ready to run to the knockup spots for 
 Blaring Drop, as well as
      moving out of an Amplifier spawn. - Good spot healing will be needed on players who are draining the pillars.

Tips for Stix Bunkjunker for Holy Priest
Defensive Tips
- If you receive 
 Prototype Powercoil, use 
 Fade when available and if in danger of death,
      
 Desperate Prayer. 
 Fade or 
 Desperate Prayer can also be used if you get low during
      
 Electromagnetic Sorting.
Cooldown Usage
 Apotheosis should be used early on 
 Electromagnetic Sorting, then counter future casts with
      
 Divine Hymn and 
 Apotheosis as available.- You should pair 
 Halo up with 
 Apotheosis and then aim to use 
 Halo shortly after it
      is off cooldown, so it is ready for the next 
 Apotheosis. 
Mechanical Tips
 Fade is great for dropping threat on the newly spawned adds to avoid getting hit, and help tanks gather them up.- Good spot healing will be needed on players who affected by 
 Prototype Powercoil. If someone with it
      looks in danger of death, this is the perfect time for 
 Guardian Spirit. - You can use 
 Psychic Scream or 
 Holy Word: Chastise on the Scrapmasters to interrupt their Scrap
      Rocket casts. 
 Purify off stacks of 
 Infected Bite, particularly from tanks if they have multiple stacks.
Best Talents
Note that this build differs from the usual build to include 
 Improved Purify.

Tips for Sprocketmonger Lockenstock for Holy Priest
Defensive Tips
 Fade and 
 Desperate Prayer are best used for the 
 Pyro Party Pack and
      
 Sonic Ba-Boom overlaps. These overlaps will happen on the second and third 
 Pyro Party Pack casts.- If really needed, 
 Desperate Prayer will help clear your 
 Voidsplosion if your health gets low. 
Cooldown Usage
- Use 
 Apotheosis around 0:50 for the bomb soak overlap, then again at around 3:50. If talented into
      
 Seraphic Crescendo you should use it at 0:50 then as soon as it's available for the remainder of the
      fight. Use 
 Apotheosis at about 0:10, then again on cooldown. - You should pair 
 Halo up with 
 Apotheosis and then aim to use 
 Halo shortly after it
      is off cooldown, so it is ready for the next 
 Apotheosis. - Holding onto Holy Words right before Magnet spawns is a great way to keep healing while having to move.
 - Use 
 Divine Hymn whenever Apotheosis isn't up, to help heal through a dangerous 
 Sonic Ba-Boom. 
Mechanical Tips
 Wire Transfer requires a lot of movement, be sure to save a 
 Angelic Feather or two for it,
      or schedule a Rescue / 
 Leap of Faith from someone to help you reposition quickly.
 Leap of Faith should be coordinated with someone who has low mobility to help them deal with
      
 Wire Transfer. Make sure not to grip people through a drill!

Tips for One-Armed Bandit for Holy Priest
Defensive Tips
- Use defensives such as 
 Desperate Prayer and 
 Fade to stay healthy during
      
 Foul Exhaust or just before 
 Traveling Flames. 
Cooldown Usage
- Use cooldowns such as 
 Apotheosis and 
 Divine Hymn for 
 Foul Exhaust which will deal
      damage and also place a healing absorb on players that you will need to heal off. - You should pair 
 Halo up with 
 Apotheosis and then aim to use 
 Halo shortly after it
      is off cooldown, so it is ready for the next 
 Apotheosis. 
Mechanical Tips
- Allies with 
 Withering Flames need to be dispelled. These dispels should be coordinated with your group
      so the resulting flames that shoot out from your dispel target don't cause accidental damage. - You can use 
 Psychic Scream or 
 Holy Word: Chastise on the Reel Assistants to interrupt their
      
 Overload! casts. 
 Guardian Spirit may be requested by your tanks to help them survive the tankbuster 
 The Big Hit.

Tips for Mug'Zee for Holy Priest
Defensive Tips
 Desperate Prayer and 
 Fade should be used if you have to soak an Unstable Crawler Mine, or
      when doing the 
 Goblin-guided Rocket split soak.
 Desperate Prayer and 
 Fade can also be used if you are not healthy going into the
      
 Earthshaker Gaol.
Cooldown Usage
- Healing cooldowns such as 
 Apotheosis and 
 Divine Hymn should be used either during the Mine
      soaks, or 
 Goblin-guided Rocket soaks. If talenting into 
 Seraphic Crescendo try to use
      
 Divine Hymn at around 0:20 then again for each mine soak afterwards. - The longer you stay on one side of the arena the more damage may ramp up. Depending on how long your raid stays on one side, you may need to pop cooldowns during the end of that phase.
 
Mechanical Tips
- The Unstable Crawler Mines can be crowd controlled, so you can use 
 Psychic Scream or
      
 Holy Word: Chastise to help keep them away from players.

Tips for Chrome King Gallywix for Holy Priest
Defensive Tips
 Desperate Prayer and 
 Fade should be used during the 
 Scatterblast Canisters split
      soak in phase one, during intermission, and during the 
 Gallybux Finale Blasts in phase three.
Cooldown Usage
- Healing cooldowns such as 
 Apotheosis and 
 Divine Hymn can be used in phase one for the
      
 Scatterblast Canisters, a split soak that will also leave a small absorb on the raid.
       - You should pair 
 Halo up with 
 Apotheosis and then aim to use 
 Halo shortly after it
      is off cooldown, so it is ready for the next 
 Apotheosis. - Phase two you will focus on the constant raid-wide healing from the 
 Giga Coils. - Intermission will have the largest burst healing requirement, and will be a great time for your second
      Apotheosis cast to heal the 
 TOTAL DESTRUCTION!!! damage. - Phase three you will be back to healing the 
 Giga Coils similar to phase two, with additional damage
      from abilities such as 
 Gallybux Finale Blast. 
Mechanical Tips
- Nothing fancy here yet, but do check back in later to see if any tricks or tips have been found.

General Defensive Usage Notes
Holy Priest 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 
 Desperate Prayer
   for large incoming damage.
 Desperate Prayer.
 Fade (with 
 Translucent Image talented).
 Flash Heal on yourself (with 
 Protective Light talented).
 Guardian Spirit (if not needed for a specific ally).
General Cooldown Usage
Holy Priest has a few cooldowns to think about using optimally on the fights in Liberation of Undermine:
 Apotheosis — Our main, 2-minute raid cooldown.
 Divine Hymn — Our secondary strong raid cooldown on either a 3-minute cooldown, or 2-minutes with
  
 Seraphic Crescendo talented.
If you find your cooldowns are not assigned by your raid leader, you should look to use these as often as they will do healing without significant overheal.
Your desired mana potion should be used as soon as the additional mana won't be wasted. This can often be quite early on during an encounter and will help set you up to have plenty of mana for the later portions of the fight.
