Abilities & Strategy
Overview
Ysondre shares health with Emeriss, Lethon, and Taerar. She begins the fight alongside the nightmare of one of her former cohorts. When Ysondre reaches 70% health remaining, the nightmare takes to the skies and a new one emerges from a nearby portal. Upon reaching 40% health remaining, the nightmare dragon in the air lands and the one on the ground takes to the air. In Mythic difficulty, Ysondre is accompanied by Emeriss, Lethon, and Taerar at all times.

The in-game Adventure Guide text for the Dragons of Nightmare encounter in The Emerald Nightmare.
The Emerald Dream was entrusted to Ysera for safekeeping, and the mightiest of her green dragon brood were assigned to stand watch over four portals that connected directly to Azeroth.
