Nightmare Dragons World Boss Strat: Lethon

Lethon is one of the 4 Dragons of Nightmare available in WoW Classic in phase 4 which went live on April 15th 2020.

As with other world bosses in WoW Classic, this boss will spawn at a random time between 2 to 4 days since it was last killed. World bosses spawn out in the world, so they can only be killed and looted once per spawn. The loot will go to the first person or raid that hits the boss. You can tell if you have the tag, and will get the loot, if the boss’s health bar is red. If the health bar is grey it will not be your loot.

Where is Lethon Located in WoW Classic

There are four portals out in the world where Lethon can randomly spawn. All of the Dragons of Nightmare will spawn at the same time and one at each portal, although the window that they will spawn is over at 48 hour period of time. The spawn locations are Duskwood in the Twilight Grove, Hinterlands in Seradane, Feralas in the Dream Bough and Ashenvale in the Bough Shadow.

How to Fight Lethon in WoW Classic

Lethon is a raid boss which will need between 15 and 40 players to defeat, depending on the skill and gear of those participating. Similar to Onyxia and other dragons, you will position the tank away from the rest of the raid. The healers and damage dealing players will be grouped on one side of the boss avoiding the tail and the head. 

Fighting Lethon as a Tank

  • 2-3 Tanks are needed or 1 Tank with +200 Nature resistance.
  • Tank the boss facing away from the raid.  All players that are not currently tanking should stand on one side of the boss to avoid the Noxious Breath and the Tail Sweep.
  • Tanks will switch at 3 stacks of Noxious Breath. If using a NR geared tank, the debuff should be resisted and not tank swap is necessary.
  • Be sure to front load high threat abilities early in your tank swap.  As you get additional stacks of the Noxious Breath debuff, you ability to generate threat will suffer.
  • You will want to keep track of the number of times Shadow Bolt Whirl has been cast and after 4 casts you will want to run through the boss to flip him around so the bolts do not hit your raid.
  • DON’T DIE! If you die you get a debuff that prevents you from making further lasting contributions to the fight.
  • BONUS: You can attempt to use the Dragon’s tail to knock those that are asleep out of the Dream Fog.

Fighting Lethon as Damage

  • Avoid the front and back of the Dragon and stand in the safer position to the boss’s side.
  • Avoid Dream Fog which looks like clouds of gas moving slowly around the area. 
  • When Lethon’s health reaches 75%, 50% and 25% everyone in the raid will be effected by Draw Spirit. As the bosses health approaches each of these thresholds you will want to make sure that you are as far away as possible. Once the stun wears off, use your quick and instant abilities to kill as many shades as possible.
  • DON’T DIE! If you die you get a debuff that prevents you from making further lasting contributions to the fight.

Fighting Lethon as a Healer

  • When Lethon’s health reaches 75%, 50% and 25% everyone in the raid will be effected by Draw Spirit. As the bosses health approaches each of these thresholds you will want to make sure that you are as far away as possible. Once the stun wears off, use your quick and instant abilities to help kill the shades.  
  • Avoid the front and back of the Dragon and stand in the safer position to the boss’s side.
  • Avoid Dream Fog which looks like clouds of gas moving slowly around the area. 
  • If you run out of mana you can run out of range of the boss and drink to full.
  • DON’T DIE! If you die you get a debuff that prevents you from making further lasting contributions to the fight.

List of Lethon Abilities in WoW Classic

Noxious Breath – Frontal cone breath that applies a stacking debuff to those that are hit. Ideally, only your tanks should be getting hit by this. For each stack of the debuff, the cooldowns on all abilities are increased by 10 seconds..

Dream Fog – Two clouds will be up at a time and will move around the boss for the duration of the fight. You will have 10 seconds from the time the cloud spawns to get out of it, after that it will put anyone caught in the cloud to sleep.  

Tail Sweep – Inflicts 600 to 1000 damage on enemies in a 30 radius cone behind the dragon, knocking them back. Avoiding the tail is even more important on these 

Mark of Nature – Players kill by nightmare dragons gain a 15-minute debuff which essentially takes the player out of the fight for the duration of this debuff due to Aura of Nature

Aura of Nature – If a player with Mark of Nature comes within 100 yards of the boss, this will cause the player to enter into an undispellable sleep for 2 minutes.

Shadow Bolt Whirl – This is a set of shadow bolts that will only be cast on one side of him at a time. He will cast this spell 4 times and then switch to the casting from the other side of his body.

Draw Spirit – Each player within 100 yards of Lethon will be stunned for 5 seconds and a Spirit Shade will spawn from their location and start walking towards Lethon. If a Spirit Shade reaches Lethon it will heal him for 1% of his life. The shades can not be hit with AOE abilities but only have around 500 health. They also walk at a fast pace toward the boss once they are spawned.
