Buggy Fight

Easy Solo for Level 120 Battle for Azeroth and Level 60 Shadowlands and Beyond...

0. Remove any gear/effects that will do automatic damage to the boss during the fight, the last thing you need is to be on 14/15 bugs stomped after some 30 minutes, and the boss dies early.

A. This will take time so make sure you've allotted at least 45 minutes for your endeavor.

1. Normal Difficulty.

2. Begin Fight. As BM Hunter, I misdirected to the pet, put in a few shots, and let Nythendra stay on my pet. Do not attack after the opening attack.

3. So after every minute and some, Heart of the Swarm begins, and near the mid point of that short phase, little Glow bugs spawn around the edge of the room.

4. Head to 50, 40 and you will find a Glow bug that spawns here, and if not, a Glow bug that spawns to the right of that spot, at 52, 37. This is important because during Heart of the Swarm, sometimes one of these bugs will not spawn, but sometimes both of them will spawn. If you are a fast enough class, you can stomp these two bugs in a single round, saving precious time. Swiftness Potion seems to work, but as a hunter I used Aspect of the Cheetah or Disengage.

5. Nythendra has a 10-minute Berserk timer on Normal difficulty, which seems to occur at the end of her 5th Heart of the Swarm phase. You may have to heal yourself.

6. Because I was using BM Hunter, I was able to spirit mend myself and utilize mend pet throughout the Berserk phase, which you will get to endure. (I suspect Shadowlands players will not have any health issues here, but this note is here just in case.) Nythendra's threat aggro kept changing between me and my pet as a result of the trading of healing abilities, this resulted in not so much damage being taken during the fight.

7. Rinse & Repeat until you fully stomp 15 Glow Bugs. I did 17 just to be safe.

8. Kill Nythendra.

9. ?

10. Profit. Achievement Completed.

Best method I've found to do this as a Solo, without use of Raid Markers.
(Screenshots included)

Patch: 10.2.5
Expansion: Dragonflight
Class: Mage
Solo: Yes
Difficulty: Normal (Do not do this on Mythic, you will die at 10 stacks)

I'll go over the basics before going through the strategy, in case you happen to be reading this comment first.

- Nythendra needs to reach 0 energy before she can cast [spell=203552] which is the phase that causes the red larvae to spawn.
- She easily does this by you just standing AFK until she casts [spell=202978] twice. Soon after the second breath, she will fall asleep and the phase will start for you to be applicable to click on larvae.
- What most of the comments here do not mention, except one or two of the top comments. Is that the red larvae to click on DO NOT SPAWN UNTIL HALFWAY/NEAR THE END of the [spell=203552] cast.

Strategy Solo:
- This took me exactly 30:00 minutes.
- I do have the utilization of two blinks, which did help me get sometimes 2 larvae in a phase.
- Using speed potions/movement speed % boost trinkets will help greatly here. But not required.
- I took 0 damage by just being able to cast Prismatic Barrier each phase. Only took around 30k~ damage a phase. 0 with the barrier.

1. Stand where shown as per this screenshot here. Use the mini-map as an indicator, this is the best (well the first spot) I found that just worked well, and I stuck with it.
2. Wait for the two casts of Infested Breath, leading into Heart of Swarm.
3. Position yourself here afterwards.
4. What most other comments don't mention is that now you have to wait for the green plague (from the looks of it) to hit the larvae, as they siphon towards the boss, for the red larvae to appear.
5. With a 100% ratio, I always had either one or both red larvae appear as shown here.
6. Count until you kill 15. Then kill the boss.

Profit. Good Game.

Since the Blizzard UI has no indication of how many bugs have been squished I created a WeakAura to track it.
