This page covers healer-focused strategies for the Halls of Infusion dungeon in Dragonflight. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences as well as Dungeon Journal and combat log information. I'll continue to update it as-needed.

Below are guides for the bosses in Halls of Infusion, including their abilities, healer notes, and addon settings.

Stage One - A Chance at Redemption

This stage begins the encounter and ends when Irideus reaches 15% health.

• When affected by Power Overload (dispel, magic) move as far away from other players as possible to drop the resulting Power Field.
• Avoid the rapid impact locations of Spark Volley (dispel, magic) targeted at all players. Players hit take moderate damage and then light damage over time.

Stage Two - Watcher's Last Stand

This stage begins when Irideus reaches 15% health and ends when he is killed.

  • Deals stacking light to moderate damage over time to all players with Siphon Power until Ablative Barrier is removed.

Mythic+ Affix Notes
