Pure Un'Goro Sample (5)

Description

Have you heard of the Un'Goro Crater, <name>? It is near the Tanaris desert, and it is a magnificent place: lush, vibrant, full of creatures and plant life.

It is there you must go. Word has reached me that the place seems completely untainted by outside hands. Explorers are just now discovering its secrets.

I would like to test the slimes or oozes there. If it is true--that they are uncorrupt--then I would like to see how such creatures have evolved.

Reward

Also, you get: 65

Progress

Yes, <name>? How goes your search?

Completion

Truly amazing, <name>. This Un'Goro Crater is holding many more secrets than I expected. I wonder what else we will discover as we test further.

Simply amazing... look at the purity of these samples. Hmm, I wonder what it could mean. They seem to be elemental in nature, but... something more. They remind me of... of the Old Gods. We've found traces of them throughout Azeroth, and now I wonder if these creatures aren't related to them somehow.

We shall have to test further.

Gains

Upon completion of quests, get:
  • 580 experience (34 80 at max. level)
  • 250 Reputation with Undercity

All the oozes and slimes I encountered had 100% drop rate for the samples. I gathered 20, just to be on the safe side, and had more than enough.

Back in UC, there are two testing bowls on the table. Use the green one for the Un'Goro samples, and the red one for the Felwood samples.

so i guess i was lucky, i took 8 samples and been in UC while making some other quest, ive tried and i got 5 pure samples from 8.

But i was less lucky with A Sample of Slime... quest ( https://vanillawowdb.com/?quest=4293 https://vanillawowdb.com/?quest=4293 ) - got 5 quest items afret testing ~30 samples.

I found a good area for these, south of Fire Plume Ridge on the map. Also on the western side north of the lake. And also by the small ponds in the south eastern side.

Test all samples before turning in the quest, to get all the drops. After turning in the quest, one cannot test anymore. It might only be worth a few silver, but it is a few silver more.

I had 15 samples and ended up with 4/5 pure, so take a stack of 20 with you to be 100% sure

Post 2.3, took 19 samples to get 5 pure. Make sure you farm enough.

(Patch 2.3) Got 4 pure samples out of 54 tested... this quest is BULLS$#@!

stack up on these things when you're in ungoro.. avoid the primal ooze, they clone themselves and you won't get any samples from the clone.

I'm glad I read about this quest before I began, because I would have assumed that ""5 samples"" meant ""5 samples""! I guess the quest giver must be an accountant. Anyway, I collected 20 to be on the safe side and it took 10 tries to get the purified samples necessary. Quest was green, got 8450 XP, 65 sp, and 250 rep with UC. Can also confirm that all around 48,65 is a good area to get at least 10 samples, I collected 10 more just riding around Un'Goro.

I got 8 of each, Un'goro gave me 4, 3 from Felwood.
Doing this even for UC rep is annoying, get a bunch, it's easier to get a bunch and have extras then fly back around.

Hoo-boy, I thought 20 would be enough. Testing yeilded 4 good samples, 3 decomposed boots, 3 gelatinous goo, 2 Large slimy bone, 2 slimy ichor, 5 extinguished torches, 1 raw black truffle, 6 broken arrow, 1 Arthas' tear, &amp; 1 scroll of Int3.
Guess I get to kill some more oozes. I personally avoid the mucelent ooze because they disease -- others do not seem to.

So 22 people reported how many tries vs. how many samples they got for this. There were a total of 337 samples tested and 91 satisfactory results. 2 were just guesses...when Quigley (the first poster) said he had more than enough, I counted that as 7, and when the next poster, Badfish, said that Quigley was on the money and wasn't able to complete the quest, I took that as him getting 4.

So what I found was a 27% rate of getting the pure sample from a tested sample. Then I actually clicked on the link for the pure sample and wowhead already did the work for me...29% drop rate.

Naturally a limited sample size, but the pure sample sizes appear to be a 100% droprate from testing. 5/5. Likely changed in 3.0.2, if not before.

I collected 30 samples from 30 Oozes in Un'Goro. Only needed 10 for testing to get 5 pure samples. v3.0.8.

By califorlife on 03/12/2009 (Patch 3.0.9)
Gathered 12 since it looked like the success rate went up with patch 3.0.8, but only got 4 samples. I suggest getting 20!

Seems like it's no longer possible to gather more than 15 samples at a time &gt;_&lt; I hope they increased the success rate (just finished collecting but haven't handed it in yet)

Indeed, 15 samples at a time possible, and I just finished with my 15. Got 4 pure samples out of those - so to finish the quest, I need to go to Un'Goro again...

I'm doing it right now, and I am unlucky. = Still only 2 pure samples out of more than 30 simple ones.

I just finished this quest and didn't have any trouble finding the Pure Un'Goro Samples. The hardest part was locating the slimes. Once I found one, the little bubble on the map showing me where they could be found disappeared as if I had finished the quest when you can collect (and should collect) 15 total, the max.

Hopefully this means that the success rate was raised and I wasn't just lucky. Wouldn't want to do that again at level 48. :/

Well when I was gathering in Felwood once I hit 15 I have seen no more drops even though when I mouse over it says they are for the quest. Until that point was getting 100% drop. Since I was doing other quest figured I would stock up just in case.
Headed to the Crater now hopefully that won't happen there as well or if it does they will have changed the chances when I get to UC.

In patch 3.3.5 only 15 samples can be collected at a time. Make sure you get 15 samples as well. Out of 15 samples collected I got my 5 pure with 3 collected left. This quest is good for your Loremaster Achievement and Undercity Reptuation too. Other than that this quest involves a lot of travel time and is mostly a time sink from Vanilla Wow. At one point it might have mattered but with the ease of leveling these days it merely aids in completing achievements. With Cataclysm on the horizon everything is subject to change.

Confirmed, max stack size is now 15.

I did get all 5 from only 10 thou.
