This page covers a healer-focused strategy for High Botanist Tel'arn in The Nighthold. 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 with the fight as well as Dungeon Journal information. I'll continue to update it as-needed.
Tel'arn is a three stage fight where he sacrafices his powers to summon Images of himself as the fight goes on.
This Stage starts when the fight begins.
This Stage starts at 75% health, when Tal'arn sacrifices his ability to cast Solar spells and creates a Solar Image of himself.
This Stage starts at 50% health, when Tal'arn sacrifices his ability to cast Nature and Arcane spells and creates a Nature Image and an Arcane Image of himself.
Healing this fight should be straightforward as long as mechanics are handled properly.
The abilities here are shared with some of the Images Tel'arn creates in Stage Two and Stage Three.
Below are the DBM settings I'll be using for High Botanist Tel'arn. You can set them up however you'd like, but these ones should work well as a starting point. Some settings may be Mythic only.
Below is a video of me and my guild defeating Tel'arn on Heroic difficulty. There is no commentary, only game sounds.
