LFR Builds
Guillotine Jaina
rumblo:CDcQARoECB0QARoECDMQARoECAgQAhoECFgQARoECDEQAhoECAkQAQ==
Important Talents
Clearcasting on Jaina discounts your spells.
Celestial Focus on Eclipse adds levels to the next immediate spell cast, which should always be Execute.
Pick Lock on Defias Bandits adds more income from the chest.
Killing Spree on Execute discounts the next Execute if you use it to kill minis like Sons of Flame.
Strategy
The initial Flamewaker rush is best answered with Whelp Eggs. Try to grab the chest in the middle with Defias Bandits while dealing with the Flamewakers.
Take out Majordomo Executus with Eclipse and/or Execute. Try to time the transition so that your minis are not right next to the Tower so that they are not taken out by the Meteor when Ragnaros emerges.
Always try to combine Jaina + Eclipse + Execute in that order for discounts and bonus levels.
Defend against incoming attacks and attack Ragnaros with Whelp Eggs, Eclipse, and Execute. You may need to use some of your Whelp Eggs for defence too.
Use your Jaina + Eclipse + Execute combo also against the Sons of Flame.
When you push into the final phase, you will need to race Ragnaros.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately.
Jaina with Whelp Eggs (also good for low levels)
rumblo:CDcQARoECAMQABoECB0QARoECAkQABoECFgQARoECBsQARoECBEQAg==
It is difficult to fit everything you want into a single army. For Jaina, the core minis are Blizzard, Whelp Eggs, and Execute. Blizzard handles large groups of enemy minis and Whelp Eggs and Execute are your main tools to damage Ragnaros.
Beyond those, useful minis include
- Defias Bandits (extra income, cheap cycle)
- Dark Iron Miner (access to the gold mines at the top)
- Gryphon Rider (great against Core Hounds and Flamewakers, cheap cycle)
- Banshee (great defensive tool against Molten Giants and Core Hounds)
- Gargoyle (wonderful mini against the Sons of Flame).
Mainly, the choice for the last slot is between Banshee and Gargoyle, as it is difficult to include both. One of each is enough for the team, so they are easy to split with a friend, but in the open queue, you do not know what your partner will bring.
If you are at a low level, bringing this build with Banshee can offer excellent support for your partner. Jaina giving +3 levels to spells while alive helps to boost your effective levels more than any other Leader.
Important Talents
Pick Lock on Defias Bandits adds more income from the chest.
Bloodthirsty on Execute gives Whelps Bloodlust when attacking Ragnaros.
Strategy
The initial Flamewaker rush is best answered with Whelp Eggs. Try to grab the chest in the middle with Defias Bandits while dealing with the Flamewakers.
Take out Majordomo Executus with Blizzard and/or Execute. Try to time the transition so that your minis are not right next to the Tower so that they are not taken out by the Meteor when Ragnaros emerges.
Defend against incoming attacks and attack Ragnaros with Whelp Eggs and Execute. Pay attention to any large groups that you may be able to Blizzard already when they are still far away from the front line. You may need to use some of your Whelp Eggs for defence too.
If you have Banshee, use it to steal Molten Giants and Core Hounds.
If you have Gargoyle, use it against the Sons of Flame. Also deal damage to them with Execute.
When you push into the final phase, you will need to race Ragnaros.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately.

Thaurissan with Worgen (great for open queue)
rumblo:CCUQARoECBsQARoECFgQARoECBEQAhoECB0QARoECCsQARoECFoQAQ==
This is one of the most balanced builds against Ragnaros, capable of handling almost any situation. Note that Worgen levels are very important for this build: it is good to use a Boost slot if your Worgen is at a low level.
If you are fighting against Ragnaros with a friend, you generally only need one Banshee. If you do not bring the Banshee, you can bring Ancient of War with Lightning Rod instead to prevent Ragnaros from mining with Dark Iron Miners.
Important Talents
Hubris on Emperor Thaurissan gives Worgen crucial extra levels.
Pick Lock on Defias Bandits adds more income from the chest.
Strategy
The initial Flamewaker rush is best answered with Whelp Eggs. Try to grab the chest in the middle with Defias Bandits while dealing with the Flamewakers.
Take out Majordomo Executus with Worgen. Do not deploy Worgen right on top of Executus or it will be noticed. Try to time the transition so that your minis are not right next to the Tower so that they are not taken out by the Meteor when Ragnaros emerges.
Defend against incoming attacks and attack Ragnaros with Whelp Eggs and Worgen. Deploy Whelp Eggs on the left, wait for Ragnaros to use Wrath, and then deploy Worgen on the right side.
Use Banshee to steal Molten Giants and Core Hounds.
Use Gargoyle against the Sons of Flame.
When you push into the final phase, you will need to race Ragnaros.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately, so save some gold to deploy a Gargoyle against it.

Sneed with Arcane Blast
rumblo:CE4QARoECBsQARoECBMQABoECCsQABoECFgQARoECDoQARoECAIQAg==
Important Talents
Torrent on Arcane Blast is mandatory: the build is based on getting extra levels on Arcane Blast to turn it into a super spell by overtime. If your Arcane Blast is at a low level, it is also recommended to use a Boost slot.
Filet Trebuchet on Meat Wagon is needed to allow it to shoot at Ragnaros in the earlier phases.
Strategy
Because this build uses Meat Wagon, you must push the right lane. When you deploy a Meat Wagon at the left edge of the middle deployment zone and send it towards the right, it will move close enough to the lava lake to aggro Ragnaros. It will catch fire and burn down, but it is still an important part of your chip damage on Ragnaros in the earlier phases. If you want to send a Meat Wagon towards the right without having it burn down, deploy it closer to the right edge of the deploy zone.
The initial Flamewaker rush is best answered with Whelp Eggs or Bat Rider. Try to grab the chest in the middle with Sneed while dealing with the Flamewakers.
Take out Majordomo Executus with Arcane Blast.
Defend against incoming attacks with Arcane Blast as much as possible: you really want to build up the levels on it. Actively search for targets throughout the map.
Attack Ragnaros with Whelp Eggs and Meat Wagon. Also use Whelp Eggs on defence as needed.
Use Gargoyle against the Sons of Flame. You can add more firepower from Meat Wagons.
When you push into the final phase, you will need to race Ragnaros. Your Arcane Blast should be quite strong at this point, so blast away.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately, so save some gold to deploy a Gargoyle against it.

Onu with Swole Troll
rumblo:CEMQAhoECBsQARoECCYQAhoECBEQAhoECB0QARoECFgQARoECFEQAQ==
You are usually left with one weakness with this build. The otherwise strongest option does not have a good way to take out Majordomo Executus at the start of the fight. If you add a way to take it down (Execute over Dark Iron Miner), you will lose some income, although that is not fatal. If you play with a friend who can kill Executus by themselves, you’re all good.
Important Talents
Fae Blessing on Faerie Dragon enables you to give Resistant to your Swole Troll, helping it survive longer.
Troll Train on Swole Troll gives it the most damage against Ragnaros. Even as a siege Specialist, it can also still attack Sons of Flame.
Pick Lock on Defias Bandits adds more income from the chest.
Strategy
Your drop zone for Swole Troll is on the left side, so you want to push the left lane. Send Onu from the right edge of the middle deployment zone to get it close enough to the lava lake to be able to drop Swole Troll and Faerie Dragon across the lake.
There is an alternative drop spot on the right side, but it is only after the first Tower, so it is much more difficult to use.
The initial Flamewaker rush is best answered with Whelp Eggs. Try to grab the chest in the middle with Defias Bandits while dealing with the Flamewakers.
Take out Majordomo Executus with Execute, if you have it, or wait for your partner to handle Executus.
Defend against incoming attacks and attack Ragnaros with Swole Troll and Faerie Dragon.
Use Banshee to steal Molten Giants and Core Hounds.
Use Swole Troll against the Sons of Flame.
When you push into the final phase, you will need to race Ragnaros. It is good if you have a Swole Troll at Ragnaros at the start of the phase change - preferably send a new Troll to push the final points of health before the phase transition - because Swole Troll adds a lot of damage in the last phase.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately, so save some gold to deploy a Swole Troll against it.

Bloodmage Thalnos with Arcane Blast
rumblo:CBQQABoECCYQAhoECB0QARoECAkQARoECBsQARoECAIQAhoECAoQAQ==
Important Talents
Torrent on Arcane Blast is important: if your Thalnos cannot reach Ragnaros to blast it directly, Arcane Blast is your secondary win condition. If your Arcane Blast is at a low level, it is also recommended to use a Boost slot.
Fae Blessing on Faerie Dragon is mandatory to give Thalnos Resist.
Killing Spree on Execute makes future Executes cheaper when you use it to kill something.
Pick Lock on Defias Bandits is vital for additional income from the Chest.
All Holy Nova talents have some advantages, but mainly the ones that improve its healing, like the Renew I’m using here.
Strategy
You want your Thalnos, or multiple copies of it, to walk all the way to Ragnaros while gaining levels. You also want phase transitions to happen when Thalnos is between Towers so that it won’t get hit by a meteor.
The initial Flamewaker rush is best answered with Thalnos and spells. Try to grab the chest in the middle with Defias Bandits while dealing with the Flamewakers.
Take out Majordomo Executus with Arcane Blast or Execute.
Defend against incoming attacks with Arcane Blast as much as possible: you really want to build up the levels on it. Actively search for targets throughout the map. Each cast also levels up your Thalnos, so try to have a Thalnos on the board as often as possible. Give Thalnos Resist with Faerie Dragon whenever possible.
Attack Ragnaros with Thalnos and spells. Use them also against the Sons of Flame.
When you push into the final phase, you will need to race Ragnaros. Your Arcane Blast should be quite strong at this point, so blast away. If you manage to have Thalnos on the way towards Ragnaros, all the better, Thalnos can then handle it.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately, so save some gold to use Execute or other spells against it.

Map Mechanics
The encounter begins with Ragnaros submerged and Majordomo Executus on the board. When Executus is killed, Ragnaros emerges, and casts Phase Transition Meteors on all Towers, capturing them and dealing lethal damage to any enemies in a radius of 10 from the Towers. Ragnaros also casts Lava Wave on both lanes even if no Towers were destroyed. The Lava Wave deals lethal damage to all enemy Towers and ground minis on its path.It does not hit flying minis.
Ragnaros used to send a Lava Wave down the opposite lane whenever he captured a Tower, but this ability was removed in June 2025. The only Lava Waves now appear at specific phase transitions: when Executus dies and Ragnaros emerges, and when the first Sons of Flame die and Ragnaros emerges again.
Throughout the fight, Ragnaros summons pairs of Core Hounds. The first pair spawns at 4:00 with one Core Hound spawning from the pool close to your base on the left and another from further away on the right. The next pair spawns at 3:00 with one Core Hound spawning from the pool close to your base on the right and another from further away on the left. More Core Hounds spawn at 60 second intervals, with each pair summoned every 120 seconds.
Whenever Ragnaros is not submerged, he casts Meteor on player-controlled Towers within a range of 30. A Meteor deals 800 Piercing damage to a Tower and minis around it on a radius of 3.5. The Meteor ability has a 10-second cooldown. Meteors are only cast on Towers that have been fully captured, not on Towers that are still being built.
Meat Wagon with range talent is able to shoot at Ragnaros over the lava lake on the right side, if you send it towards the right Tower from the left edge of the middle deployment zone. Blizzard did not enjoy this strategy and implemented a special Meat Wagon burn zone around the area. Any Meat Wagon that enters the area takes 70 Elemental damage per second after 8.5 seconds in the zone. This damage effect lasts for 120 seconds.
Phase 3 begins at 70% health
- Ragnaros cleanses itself of Burn and Poison
- Ragnaros submerges. While submerged, Ragnaros is immune to all damage and the area around Ragnaros is on fire, dealing 30% of a mini’s health in Piercing damage every second in a radius of 10 around Ragnaros
- Ragnaros summons four Sons of Flame, two on each lane
When all four Sons of Flame have been killed, Ragnaros emerges.
- Ragnaros gains a 90% damage shield for 5 seconds
- Ragnaros stuns all enemies within a radius of 10 for 5 seconds
- Ragnaros casts Phase Transition Meteors on all Towers, capturing them and dealing lethal damage to any enemies within a radius of 10 from the Towers
- Ragnaros casts Lava Wave on both lanes even if no Towers were destroyed
Phase 4 begins at 40% health
- Ragnaros cleanses itself of Burn and Poison
- Ragnaros gains a 90% damage shield for 5 seconds
- Ragnaros casts Phase Transition Meteors on all Towers, capturing them and dealing lethal damage to any enemies within a radius of 10 from the Towers
- Ragnaros summons five Sons of Flame, including one between your Barracks and the chest
- Ragnaros gains the Raid Base Meteor ability and starts shooting at your Barracks every 30 seconds
In phase 4, Ragnaros will resummon any Sons of Flame that have died every 67 seconds.
General Strategy
The Ragnaros fight has changed considerably from its original version. It used to be important to only push one lane, but now you can freely mix and match and attack from both sides.
The side that you choose usually does not matter, with two exceptions:
- Onu wants to push up the left side because the best drop zone is on the left
- Meat Wagon wants to push up the right side because the only spot where a Meat Wagon can shoot at Ragnaros is on the right
Beyond that, there are many ways to beat Ragnaros.
The initial Flamewaker rush is best answered with Whelp Eggs, although there may be other minis mixed in on either side, which may require more answers. Try to grab the chest in the middle as soon as possible while taking down the Flamewakers on the sides.
Next, you need something to take out Majordomo Executus.
- Spells like Blizzard and Execute are effective
- Worgen (do not deploy it right on top of Executus or it will be spotted)
- If you use a ground strategy, you can also get to Executus with ground minis, although this takes more time
Whelp Eggs, on the other hand, are notably inefficient because Executus destroys them so quickly.
When Majordomo Executus dies and Ragnaros emerges, you will lose any Towers you had and minis that are right next to them. Try to time the transition so that your minis are not right next to the Tower so that they are not taken out by the Meteor. Be ready to retake Towers.
Then, you start attacking Ragnaros to get to the first phase transition.
- By far the most popular way to attack Ragnaros is to use Whelp Eggs and Execute, but there are other alternatives.
- Deploying Whelp Eggs on the left, waiting for Ragnaros to use Wrath, and then deploying a Worgen on the right side is a very effective way to deal a lot of damage to Ragnaros.
- You can also shoot at Ragnaros with Arcane Blast with Torrent talent to build it up as a major threat
- You can send a Swole Troll to Ragnaros over the lava lake with Onu
- You can use a Meat Wagon to shoot over the lava lake (note that there is a special burn zone that will destroy your Wagon after a while)
- You can send ground minis like Drakkisath to hit Ragnaros
At the first phase transition, Sons of Flame will spawn. You need to be able to take them down.
- Resistant tanks are the best to keep Sons of Flame in place
- Sons of Flame take extra Siege damage, so minis like Gargoyle, Swole Troll, and Meat Wagon are highly effective against them
- Sons of Flame take full damage from Execute
When Sons of Flame die, Ragnaros emerges and meteors all the Towers again. Be ready to retake Towers.
When you push into the final phase, you will need to race Ragnaros. Depending on your levels, you may want to wait until overtime to start the race. This is where spells and unbound minis are especially strong. Alternatively, you need to have strong enough of a deathball that it survives the phase transition and can continue dealing damage to Ragnaros throughout the final phase: this is most easily accomplished with Drakkisath because of the Resistance aura it provides.
Also note that an additional Son of Flame will spawn between your Barracks and the chest, and you need to answer it immediately.
