I’m working on a detailed list but I think this deserves its own thread
Rich Thorium is 100% bugged. After about 5 days of on and off mining, I found about 50 RTVs. Of these, I got a grand total of 2 gems, 1 star ruby and 1 diamond.
That’s it. As far as arcane crystals, I have gotten a grand total of 1 my entire time in classic, with well over 100 RTVs mined.
Rich Thoriums are not only bugged by routinely having only 2 hits from them, but gem drops are far too low.
It has gotten so bad, that Arcane Bars have hit almost 60g ea on my server. Crystals alone are going for almost 40. Alchemists are advertising constantly not because people don’t need transmutes, but because even people farming full time cannot get them. It’s super disheartening when you see a Rich Vein and don’t even get excited anymore, because not only are you expecting 2 hits, but because you know there won’t be a gem in it.
I did some research on RTVs and found out the 3% drop rate for ACs that blizzard is most likely using is wrong. RTVs do drop ACs at a 3% rate, however, this is per hit. Meaning, averaging a 3% chance, and considering each event is independant because there are reports of multiple ACs in a single RTV, the math would be for 3 hits
1-(0.97^3) = 8.73% chance per vein of getting an Arcane Crystal
For 4 hits it would be
1-(0.97^4) = 11.47%
Meaning my 50 veins, averaging 3 hits per, the odds of not getting an arcane crystal is
(0.97^50) = 21.8%
Which seems possible, but then you add in the percentage of the other gems, and how only 2 dropped. The values definitely seem off.
When I talk to other miners, one who mined for 8 hours straight said he never saw a single arcane crystal. Reports on thottbot show drop rates as high as 1 in 3.
Arcane crystals are exceedingly rare, and there are reports that blue sapphires aren’t even on the loot table which is obviously a bug. All the blue saphs I have gotten have been from small thoriums. In fact, the majority of my gems have come from small thoriums. Rich thoriums aren’t rich at all.
As a miner, I actually am going to give up on making my Breastplate of Bloodthirst because of the Arcane Crystals. That is absolutely insane.
I should be able to farm them myself, but after what I’ve seen that is basically impossible. You would spend a solid month to have a chance at 5 bars. Next to nobody can afford 60g each for arcanite bars, can you imagine trying to make any sort of decent weapon on my server?
I just want it to be known that rich thorium is bugged and needs to be addressed.
Arcane crystals are probably the most important resource in the entire game and when you have miners giving up on farming them that is not a good sign at all
