Lethon, Dragon of Nightmare – 20th Anniversary World Boss

Welcome to our World Boss Guide for Lethon in the 20th Anniversary Event! There were the four Dragons of Nightmare who guarded the portals to the Emerald Dream in Vanilla WoW. They have returned for a limited time for World of Warcraft’s Anniversary.

Only one of these dragons spawns at any given time and they rotate on a daily basis. You can see the time remaining on the current dragon by hovering over their icon on the world map.

This World Boss is required for the achievement The Originals.

Lethon Abilities & Strategy
