Achievement Objective: Kill Maexxna in Naxxramas within 20 minutes of Anub’Rekhan’s death on Heroic Difficulty.

In other words, you have 20 minutes to clear out the entire Spider wing. So how do you make your raid leaner in terms of time?

Loot decisions

The clock starts ticking the moment Anub’Rekhan’s carcass hits the floor. Assuming you have 1 tank and 1 healer who do not need loot, they can jet out the door and start clearing the next set of trash. Ideally, players won’t need loot from Anub’Rekhan or Faerlina at all and the loot master can wire all items to the disenchanter so everyone can move on.

But that’s unlikely.

Faerlina

Have a Priest start blowing up the Worshippers. Yes, before she enrages. If you have every healer tasked to the main tank, then they should stay up. By blowing up Worshippers, you can save yourself precious seconds of DPS time.

Heroisms/Bloodlust

If you have two Shamans, you get access to 3 Heroisms. If you’re really good at timing, you can squeeze off one on Faerlina, one on the trash pull to Maexxna, and one on Maexxna herself.

Trash Pulls

There are a few pulls that you can skip. I know there are a pack of spiders that patrol up to the ramp that lead to Maexxna’s chamber. Time it right and you won’t have to deal with them. But if you have to take them out, try to slowly drag them up the ramp and kill them there.

Cooldowns

Speed is of the essence. Every trinket you have, blown. Every cooldown, used. Every nuke, critted. I spot the highest caster DPS on my active Recount and throw them a Power Infusion as soon as it is up.

If you can focus and channel your efforts, this will be an easy achievement to attain. Chain pulls are the order of the day.
