I just thought I'd see how this goes. I'm going to update this post later once I test it out some more, but out of one stack of crystals I've gotten:
Sheep Leather x1: 4 times Iron Ingot x1: 3 times Iron Ingot x2: once
Leather: 55 Smithing: 0 Earthsday facing south
edit:
Second stack of crystals Sheep Leather x1: Once Iron Ingot x2: Once
Third stack of crystals
Sheep leather x1: five Iron Ingot x1: once
So I don't know. I'm going to keep raising my leather, and my luck seems pretty decent now. So when Lightning day roles around I'll test out my luck again. This time it wouldn't be worth it to try and make good money, but once I get leather up there enough I might just sit around and HQ these for a quick buck.
I know this hasn't been posted on in some time, but the question still stands sorta, and thats if you need smithing or not. I Can desynth these into iron ingots and I have 35 leathercrafting and thats it. Kind of rare to get 2 ingots from one desynth, but it happens. 40K a stack on my server. Sheep leather is 30K a stack if you don't get many HQs outta it.
How on earth do you get iron ingots from these? It says it is a smithing skill, but I surely can't get anything from them in 20 attempts on lightnings day. Do I need leathercraft ALSO to get ingots?
u will need to get some skill point (mine is at 71) in leathercraft, the only catch is those are very rare, b/c they are hq desync. have fun normal: sheep lether x1 hq1: sheep leather x1 hq2: iron ingot x1 hq3: iron ingot x2 (got that twice lastnight)
This is just a speculation, I havn't been able to put it to the test yet, but, given a guess, I'd say that the recipe for this would be: 1 lenght of iron chain and 1 square of sheep leather combined using a wind crystal.
