Against my better judgement I subjected myself to around 20 hours of testing related to gathering professions and scarce materials over the last few days, mainly to figure out why attempting to craft a set of Stormrider Leather for my shaman was going to cost over a hundred gold. I did an absolutely insane amount of skinning and a fairly large amount of herbing across a variety of characters leveled 1 to 30. I did not test mining at all and invite others to do the same.
My understanding of how Tier 1 scarce materials (Pristine Leather/Frilled Lichen/ probably Pyrite also) work is now the following:
Pristine Leather - Can only be produced by a level 1 to 25 character skinning a level 10 to 25 mob.
Edit: 10/15 additional testing suggests I was wrong about the “mob can’t be grey” part that was previously here.
Frilled Lichen - Can only be produced by a level 1 to 25 character picking the relevant herbs (Earthroot/Mageroyal/Briarthorn/Bruiseweed/a few others)
I am not 100% sure about the level 25 cutoff, I need to push a few more alts to 26-27 and maybe torture myself some more. I am 99-100% sure that level 30s can’t gather these items though.
In short, as they’re currently implemented, gathering these materials relies on lowbies, and after Forever has been out for a while, high level players will likely find it more practical to buy them from the black market vendor. Whether this is the intended economic gameplay loop for these items I have no idea.
For the most part these items are used in level 10-40 gear and enchants, although there are a handful of datamined level 250-300 crafting recipes that need cerulean dye or pristine leather (runecloth bag, mooncloth reagent bag, invulnerable mail to name a few).
Testing methods:
-A level 30 char killed and skinned ~300 sunscale scytheclaws at the stolen silver quest area without getting a pristine leather. The same character then went to High Perch and killed wyverns, yielding a Pristine Hide (tier 2 scarce leather) in under 20 kills
-A level 22 char killed and skinned about 30 sunscale scytheclaws (green, about to turn grey) and got a Pristine Leather. The same char then killed around 200 of a variety of grey barrens wildlife (savannah prowlers, tallstriders, etc) without getting another pristine leather.
-A level 1 skyborne was leveled through Zephras with herbalism and skinning. By level 13 it had a full stack of Frilled Lichen by picking literally every single earthroot and mageroyal it saw while otherwise questing fairly normally.
-After I was out of quests, the same skyborne grinded on level 10-12 zephras beasts to the tune of about 200 kills without getting a Pristine Leather. I believe zephras mobs cannot drop Pristine Leather. It then went to crossroads and got a pristine leather before it found four zhevra hooves.
-A level 25 character dropped a profession and learned Herbalism, then ran around Durotar leveling it. It had a frilled lichen in its bags from Earthroot within about 10 earthroot nodes gathered.
Still to do: Let the level 25 character hit 26 and then do enough flower picking to see if 25 really is the cutoff.
In closing I would like to say please buff Ele before release.
