Sapphiron 10-Man Boss Strategy

Make sure to check out the complete Naxxramas 10-Man Instance and Boss Strategy Guide.

Sapphiron is the 1st boss within the final wing of Naxxramas, Frostwyrm Lair. This ancient blue dragon was once servant to Malygos and the head of his brood until he was struck down by Arthas. Arthas used what was left of his necromantic powers to resurrect Sapphiron as a frost wyrm. Sapphiron, now an implement of chaos for the scourge, guards the final passage way to the very lair of Kel’Thuzad.

Sapphiron Abilities

  • 4,250,000 HP
  • Frontal Cleave, 180 degrees
  • Rear Tail swipe, ~45 degrees
  • Phase 1
    • Frost Aura – deals 1200 damage per second to every member of the raid throughout the fight.
    • Life Drain – deals 2200-2800 shadow damage to targeted player and heals Sapphiron for 4400-5600 every 3 seconds. This is a curse, it can be dispelled. Players who get this should immediately call out on vent to be dispelled.
    • Chill aka Blizzard – this blizzard like spell deals 3500-4500 damage every 2 seconds to those standing within it’s AoE. All players need to be aware of the Chill’s position and do what they can do avoid taking any damage from it.
  • Phase 2 – every 45 seconds
    • Ice Bolt – puts 2 players in your raid in a block of ice, dealing 5000-7500 damage to the player and players close by in a small AoE. The raid must stand behind these blocks to survive frost breath (see video below).
    • Frost Breath – anyone not behind the blocks of ice will be 1 shot (over 100,000 damage).

Sapphiron Boss Strategy

The Entry and Healer’s Setup – You’ll want to split your raid into 2 groups. Group 1 should go left and group 2 right. Each group will have 1 dedicated healer who will be solo in charge of healing that group. With mediocre gear it’s still possible to duo heal Sappphiron, but difficult. For players just learning the encounter I would suggest using 3 healers, where there 3rd healer’s primary job is healing the main tank.

note: scroll all the way to the bottom for the video tutorial of these steps.

Phase 1 – Generally speaking this phase is a standard tank and spank fight. I’ve mentioned the phase 1 abilities above, so you’ll need to be aware of all of these. Simply keep the AoE heals cooking and don’t let anyone get too low, especially as you’re nearing the phase 2 transition. This transition is when most player’s are going to die due to the potential spike in damage due to the ice bolt.

Positioning and Liar Layout

  • Red circle – this is the outer wall of Sapphiron’s lair
  • Green circle – this is the interior green circle on the floor, I use this as a point of reference below regarding phase 2
  • Blue oval – Sapphiron’s body, note that Sapphiron’s head should be facing towards Kel’Thuzad lair

Phase 2 – This phase begins as Sapphiron flies up into the air. He will go up and ice bolt 2 players at random, these players now act like shields for the frost breath. Players nearby should all gather behind these players, doing so will prevent you from being hit by the frost breath.

Note: it’s helpful to gather up during this phase so you aren’t so spread out that you can’t get behind the ice block shields. My guild collapses around the green ring in the center, staying close, but also spreading out in a circular fashion around it’s perimeter. You need to spread out a bit to avoid the AoE frost impact damage on the ice bolt.

As soon as the ice bolt block is up you should immediately get behind it and healers should be topping off the raid.

Note for DPS Players – As a DPS there isn’t much you need to worry about…but there are a few things.

  • Watch out for the frontal cleave, if you get hit by this and aren’t wearing plate you’re probably dead. It’s 180 degree frontal cleave, so make sure you DPS closer to the hind legs.
  • Watch out for the tailswipe, simply stay away from the tail, not very difficult.
  • Be aware of the blizzard’s positioning in the room and do your best to avoid taking any damage from it. There’s no need to put additional pressure on your healers.

Phase 1 / 2 Continuation – At this point you’re essentially in a loop of the above 2 phases of listed. Phases 1 and 2 will continue until you’ve either killed or wiped to Sapphiron. Simply continue the steps I’ve listed above and you’ll be well on your way to your first Saph kill!

  3. hey,

    first of all, nice website! :)
    i am guild leader from my guild and we cleared naxx 10 man.
    i have a little tip for this boss.

    do not split the 2 groups on 2 sides of the boss. place the entire raid on 1 side of the boss this way its easyer to heal/decurse. the only thing wich will be a bit harder is the splitting up when he does the iceblock thingy.
    as for melee dpsers they can be healed easyer by shamans ( chain heals )
    i sugjest you get 3 healers in this fight.

    hope you got some good information from my comment,


  4. Hey Boneys, thanks for the kind words and your input.

    You could certainly put the entire raid on one side, the only issues with this are…

    1. making sure the raid gets spread out enough when he goes up into the air
    2. making sure a cleave doesn’t get chained through the entire raid, IE, wipe.

    As far as healers are concerned idk if I’d say shamans are the end all be all healers for this fight. Yes, chain heal is fine and will suffice, but there’s no reason a good druid or priest couldn’t do the same. Paladin is the only healer where they would be a significant disadvantage compared to other healers.

  5. Heya

    Do you need any frost resistance gear for this, and if so how much?


  6. Frost resistance gear is unnecessary for most guilds. You could use it if you have it, but thus far all my guild has used is paladin frost aura or shaman frost resistance totem. This in combination with mark of the wild should be sufficient.

  7. Mark of the Wild doesn’t stack with the Paladin aura or the shaman totem.

  8. ah…yes, you’re correct, temporary brain lapse on my part.

  9. The three-peice resist set actually made a huge difference for my group (except for the tank which loses too many defense stats to use them).

    The Icebane set for my pally was only about 500g worth of mats for all 3 peices and stacked with the aura gives almost 450resistance (Excellent).

    I agree, it’s not totally necessary, but if you’re running with 2 healers then the DPS players can help the healers keep from ooming and make life a whole lot easier with some resist gear…


  10. Da Man is right. If you run with three healers, then the frost resist is unnecessary. If you run with two like we do, you will probably lose at least one or two people if at least half the raid does not have one or two pieces on. Its so cheap and easy to make that I’d suggest to any guilds that are new to the fight that everyone get one or two pieces made just to make it that much easier.

  11. i suppose you’re both correct…but it still feels completely unnecessary. So long as your healers are geared and competent + either paladin aura or shaman totem you’ll be fine.

  12. Thats true… we heal it as druid/priest, and bring neither a paladin nor shaman unless we have to pug someone.

  13. “Now an implement of chaos for the scourge, guards the final passage way to the very *LIAR* of Kel’Thuzad.”

    I think you mean lair ;). On another note, thank you. You have written some amazing material here. I have been over all your guides and they have helped to review and buffer all my raid tactics for my guild. You have really done a incredible amount of work and quality work at that. Keep up the amazing job.

  14. hey chris, thanks for catching my typo and all the feedback. It’s much appreciated!
