Forgotten Experiments Raid Guide - Normal/Heroic Aberrus Guide

The Forgotten Experiments Normal Heroic guide! Forgotten Experiments is an early boss fight in the Aberrus raid of Dragonflight. This Forgotten Experiments guide for Forgotten Experiments will walk you through the important healer, tank and DPS raid mechanics you need to clear this Aberrus raid Forgotten Experiments.
Special thanks to Occasional Excellence for the raid testing groups!
You fight Forgotten Experiments in three phases as you face each experiment in turn. All three bosses use Infused Strikes on their tank- it stacks a debuff that needs to be cleared by colliding with the other tank when they also have stacks. Doing so puts out a raidwide DoT, so space out your clears.
Neldris is first, and she does an AOE to move away from with Bellowing Roar, a frontal cone with Massive Slam and a charge-between-players that leaves a bleed in her path called Rending Charge.
Thadrion is second. Dodge Volatile Spew swirls, heal through Violent Eruption raid damage and be delay dispelling the Unstable Essence DoT as long as you can to avoid excess explosions.
Third, you fight Rionthus the dracthyr. Spread away from the Disintegrate targets, body block the Temporal Anomaly from reaching the boss and get out of the path of Deep Breath.
Heroic Forgotten Experiments gets longer bleeds from Neldris and adds that spawn after each Unstable Essence dispel. Don't dispel too often!

Hi Hazel, team and guild. I love your guides to raid bosses. Thank you for your continued service.

[@aimene_.]

Blizzard need to add a section for your videos in the Adventure Guide ! Always amazing guide thank you

[@GOOOOOOOOOOOOODDAY]

You literally make the best guides, i watch maybe 4 different videos on the same boss before i do a fight and ive just transitioned into watching just your video as its all i need. Thank you for your service

[@meatman69420]

are tanks supposed to swap on every infused strikes then? sorry if it was explained in the video somewhere, but i didn't hear anything about swaps.

[@MrSacredcrusader]

the tanks bonk together. she says it at the very beginning of the video

[@meatman69420]

@MrSacredcrusader yeah did that and still got flamed by my groups claiming I wasn't swapping so..

[@lalalala9734]

when ever my group does this boss we have like NON stop orbs spawning what are we doing wrong? because im in a group that just did it and there were only 2 the whole time

[@nugget7865]

probably a combination of low p2 dps and trigger happy dispels

[@legitgaming5522]

i like how you skipped the part on how many stacks both tanks should have...

[@peteyf5806]

[@souleater1277]

Hmmm Some guilds say Unstable Essence is permanent from Thad onwards or was it a bug in PTR?
