It's a ferret!

Comment by Niixten

This is not something you would get passively since most of the time you kill rares and do quests for assault completion. The best way to do it would be in a raid group while watching netflix and etc.

Edit: as long you don't kill the end boss in the assault you can still click on those tumors! Uldum is far the best zone to do this achievement in.

Just made a raid group and went to town while on the Assault quest.

Comment by williee

Based on some testing, if you are trying to do this achievement in a raid group or party, only players within your group will give you credit. So if you have 4 groups (20 players), if a member in group one pops a tumor, only players in group 1 will get credit to the achievement. This is what I see from the brief testing I've done so far.

So doing this in a party might be the most efficient route. If you are scared someone will kill the boss or something and end the assault, you can have a group of 5 and convert it into a raid group, preventing the boss credit if it dies.

Comment by rav430

If you click very carefully, rogues can destroy these without leaving stealth. allowing you to skip fighting the surrounding trash.

Comment by Djuntas

Go down the south part of uldum, realm hop around there...quit a few tumors where there are water etc. So same area where you find the alpaca flower. Anywho take your time, its still boring.

Also! You can fill up the assault bar/quests, and still click on tumours...once you turn it in its over.

Comment by Buuloki

The best way I've found to do this (in Uldum):

You can do this in a party or just by yourself. Do this on a day the quest Cleansing Uldum is up. Don't hand in the quest once you have it, just keep it. It will automatically drop on daily reset though.

Go to the Akhenet Fields in Uldum (55, 51) here you can find quite a few Corruption Tumors within a close proximity. Fly up and down this field area clicking tumors. These respawn fairly quick and you can get most of these without aggroing a mob, or only aggroing one or two.

Click on these tumours over and over until you've collected 1000!(##RESPBREAK##)268##DELIM##Buuloki##DELIM##

Comment by Elodeon

Doing this as a Servant of N'Zoth makes it trivial: all the NPCs become neutral, so you can just fly from tumor to tumor and click them. It's feasible to do 340 per hour on a known circuit route if there's no disruption.

Around the Lost City of the Tol'vir in Uldum, there are about 17 spawn points of these tumors, each with the three NPCs around them. If you don't kill the mobs, the tumors respawn in the exact same spots in 3 minutes. This happens to be about the same time it takes to complete a circuit. If no one else is disturbing the mobs – such as late at night – you can complete this in 3 hours flat, once you memorize the locations of the tumors.

You do not have to be in a raid group to avoid progress on the assault - it's sufficient to just not kill the final assault boss. Once you reach 100% progress, the tumors will become less obviously visible, but will remain clickable.

Comment by Wyler

Do this on a druid if you can (if you don't have servant of n'zoth) - you can pop the tumors in flight form. If you're having issues with aggro interrupting your pops, make sure your angle of attack is around 45 degrees (with no npc below you), as opposed to directly above the tumor.

A rogue is also a good choice if you don't have a druid as you can pop them in stealth and mount up with no issues.

As other posters have said, you can do it all in one go if you just don't finish the assault.

Comment by Rubinova

Fastest way so far for me
1. Wait for Black Empire Assault pop up in Uldum
2. Head to Tahret Grounds (60 37) and Vir'naal Oasis ( 60.35)
3. Make route between following points in mentioned areas:
/way 60:42
/way 60:43
/way 61:41
/way 62:39
/way 61:35
/way 60:33
/way 60:28
/way 59:29
/way 57:24
/way 58:28
/way 59:32
/way 59:38
/way 59:41
/way 60:37
/way 60:28

With this "route" i've collected 100 tumors per 20 minutes, with killing mobs most of the time so with good class You might have even more.

Tips:
- You don't need to create raid group to stop the progress of completing the Assault. Just simply after finishing 100% progression on the Assault forces, don't kill the "final boss" of the Assault.
- If You have N'lyeth, Sliver of N'Zoth You can use it to avoid going into combat with the mobs, note that You do not belong to any faction after using it
- Best class for this achievement is rogue or druid - You can click tumors in stealth or in flight form without aggroing the mobs around them.

Comment by MarshaII

I dont really see what the purpose of of this achievement

Comment by Trelander

Ok fastest way by far is with two people - obviously this won't work for everyone, see other posts for other options.

Basically first person should be a tank if possible, and "baits" away mobs, lands and moves on the ground away letting a follow up person come behind and click. If that follow up person is a druid (for no dismount click), you can get 400-500 or more an hour easily.

Use the top right river, go up the river, back down, past the fields with the slimes and nodes, down the hill towards the town, around the town, and back up the other side. Just loop this, they all refill before you come around.

I know this won't fit everyone's needs, but if you can find someone to go with like this it's much much faster.

Comment by VremGO

Below are all the tumors that spawn around the main portion of the lake. I was able to average 120 tumors per 20 min, 360/hour following this route. I'm sure by cutting some of the inefficient parts of the route, it could probably be closer to 400/hr.

Comment by jirojin

this achievement should sound familiar to every Hellboy fan who watch the Golden Army

Comment by drunkenhugo

I managed to complete this in just under 2 hours with the Servant of N'zoth toy. I just made a route from north to south around the Hungering Miasma rare, making sure the 11 tumors close the rare would be respawned anytime i passed through the rare mob area.

Comment by Volleynova

Easy, however extremely repetitive Solo Achievement for Level 120 Battle for Azeroth, Level 60 Shadowlands, and Beyond...

0) Assault: The Black Empire must be up, and you can be at 100%, just don't turn in.

1) Head to Vir'naal Oasis and the Tahret Grounds in Uldum.

2) There are plenty of Corruption Tumors within the Grounds and surrounding Oasis.

3) Do a clockwise motion around the entire area destroying tumors and the mobs surrounding them.

4) You'll find that in time the tumors can respawn without mobs present, saving vital time. Not looting the mobs saves time as well, they didn't seem to drop anything of use either way.

5) What takes up the most time is the mobs around the tumors so make sure you utilize the AoE capabilities of your class and it's much faster.

6) I was able to complete in just a handful of sittings, some ranging from 30 minutes, some 2 hours, and did 600 tumors in my final sitting which was about 3 hours.

7) ?

8) Profit. Achievement Completed.

Comment by AzerateAeriePeak

Use a druid. You can destroy the tumors in flight form without fighting the mobs around.

Comment by ekrietlow

I'm actually surprised it hasn't been mentioned yet, but this Achieve is a hat-tip to the phrase Arnold Schwarzenegger says during the movie Kindergarten Cop, if you were curious.

Comment by Qoko

If you have any way to create a (semi-)permanent stealth (Rogues and Ferals by default) you have a clear edge for this achievement. As Rogue with a speed set equipped (195% with Nightstalker) I am essentially floating from tumor to tumor and it becomes a matter of just creating time to do it.

Comment by Klausnomi

Can confirm - Monel-Hardened Stirrups DO NOT work with popping

Comment by mooklik

If you want to tick this one over while being semi-AFK you can sit on the terrace in Uldum at 52,50. There are 2 tumours quite close that respawn every couple of minutes. No mobs come up here so you can click them both, stand there safely and do something else for a few minutes, then come back. Would take a very long while to get 1000 this way, but ok if you're doing something else at the same time.

Comment by Getwasted

59.66 39.49 is the place where I found it it the fastest to farm them. They keep respawning and you can just make small circles in one area.

Comment by Mauser13

All these comments with the best places and a list of waypoints, maybe mention if its in Vale or Uldum first?

Comment by JeackTL

I tried several routes, and I have recommendations for doing this with and without the Servent of N'zoth toy.

With the toy, circle the area bounded by these waypoints in Uldum:

/way 58.9, 44.5
/way 60.5, 58.7
/way 58.5, 60.7
/way 51.6, 49.6

There are approx. 30 tumors per loop, and the respawn time syncs well with the route. I was able to complete this in under 2 hours using the Servent of N'zoth toy that makes you neutral with black empire mobs.

Without the toy, your route needs to be more concentrated so you aren't killing lots of mobs. I recommend cirlcing the town around 55.3, 51.9 in Uldum. It has by far the highest concentration of tumors of anywhere I found, and most mobs are low HP (there are probably 15 tumors in this small area)

Comment by Csofe

This achievement should award the title Pimple Popper

Comment by pauladin

Takes about 30 seconds to clear the mobs around the tumor before you can mount up and fly to the next one.

1000 tumors * 30 seconds per tumor

= 30,000 seconds
= 500 minutes
= 8.33 hours

Comment by Dedux

Please see Elodeon's original comment here that i have quoted below - make sure to upvote him!

Doing this as a N'lyeth, Sliver of N'Zoth makes it trivial: all the NPCs become neutral, so you can just fly from tumor to tumor and click them. It's feasible to do 340 per hour on a known circuit route if there's no disruption.

Around the Lost City of the Tol'vir in Uldum, there are about 17 spawn points of these tumors, each with the three NPCs around them. If you don't kill the mobs, the tumors respawn in the exact same spots in 3 minutes. This happens to be about the same time it takes to complete a circuit. If no one else is disturbing the mobs – such as late at night – you can complete this in 3 hours flat, once you memorize the locations of the tumors.

You do not have to be in a raid group to avoid progress on the assault - it's sufficient to just not kill the final assault boss. Once you reach 100% progress, the tumors will become less obviously visible, but will remain clickable.

I have compiled a list of waypoints for the Corruption Tumor spawns I have found around the Lost City of the Tol'vir for the route he mentions. The spawns do seem to vary and some aren't always available (i think they change daily). I can confirm this route is very efficient and you will easily be able to complete this achievement in the timeframe Elodeon mentions.

Comment by Hemingray

As of Shadowlands, at level 60 (without the PvP toy) you can easily farm in Akhenet Fields without aggroing the nearby mobs. I could get around 8-12 nodes per minute, with a 1-2 minute respawn.

The hardest part of this achievement is staying motivated due to its purely grindy nature.
So here are some recommendations from a psychological point of view:

Don't force yourself to do the whole collecting in a single session.
Instead, set a daily goal and do it over a span of several days / assaults (143 Corruption Tumors / day if you're aiming at completing it during the weekly major assault).
If your daily goal is over 100, consider splitting it into two sessions with a break in between.
If you like PvP, do a couple of BGs for some diversion.
Lastly, the achievement is a good opportunity to do Combating the Corruption along with it.

Happy farming!

Comment by Tandestoker

Warmode on with the silver of n'zoth toy to not aggro any mobs on my druid.

Took me 1h30 to get 700 during n'zoth assault in uldum.
Took me 3h to get 300 during n'zoth assault in vale.

Rice field under the bridge to the left in uldum is the best spot. Other good spots are along the river and top right above the bridge.

Wouldn't recommend farming in vale AT ALL.

Comment by Elinoredris

I just completed this achievement today.. 4/13/23! I started out with 300 that i previously farmed in Vale. I decided to give Uldum a try and I must say I farmed 700+ in a matter of roughly 2 hours... so to save you time. I suggest going to Uldum and farming the tumors flying throughout that whole center zone. Good luck & happy farming!

Comment by Bathrezz

If you have two accounts, make a group, you will get double credit for each Tumor,

The annoying part is that you get dismounted when clicking on Tumors, you will need to remount and get ur 2nd account to hop on back on every time. It still works out to be faster than going solo, i got 50 credits in 10mins.

With the above said, credit for clicking on Tumors does not reach across the zone, you must be nearby thats why you need a 2seater.

Comment by Robinhewd

Idk if it's a bug or not, but after completing the assault WQ, I couldn't interact with the tumors anymore. So don't complete (as in turn it in) WQ to keep interacting with em. But can just hop on an alt and continue. Also, bless those who have posted the coordinates.

Comment by WokkaD

A reference to Kindergarten Cop (Arnold Schwarzenegger) :
He's in the classroom surrounded by 4 year olds.
Has a "headache".
The kids suggest all sortd of things. One says "it could be a tumor". Arnie yells back "it's not a tumor".

Comment by RalexB

--EDIT-- As per Wowhead news () the number of tumors requires has dropped to 100 (previously 1000) so don't waste your time if you're already over 100 on the tracker!
Something interesting I noticed - Whilst this achieve references 100 kills - the ingame achieve still references 1000. Im sitting at 129 so im eager to see when the meta achieve arrives if it will pop the achieve for 100 or I will have to go and farm... If I get away with it... hekhekhekhek

Comment by Kravex

The quest Cleansing Uldum requires you to destroy 6 corrupted tumors. If you've already finished the assault and can't target them just take this quest if it's up, destroy 5/6 and then abandon it. Retake the quest and you can go out and destroy 5 more. Rinse / Repeat. Bit time consuming but gets the job done.

Comment by ThyrazOnSpotify

omg I did this when it was 1000 required I feel so bad right now why didn't I wait

Comment by tristris

For anyone still doing this in 2026

If you have the daily quest to destroy the tumor.

Take quest
Create raid group
Now you can farm all tumors while also have the benefit of the quest not progressing but your achievement still do.
BEST of all, you still can see the glowing outline of the tumors.
