So I searched for the ID for Snow Spider's Web, and I found it in the mission drop table (and the spider in monster.xml references this as a bonus drop entry). Looks like it's done this way to give mission monsters different drop pools on different difficulties.
Out of difficulties 2, 3, and 4... the spider has equal drop pools, the only thing that differs is the chance of the rare one. So Advanced should work as well as Hard (assuming 1234 are increasing difficulty). In both of those difficulties, the pool contents are...
Pool 1 (150,000): Cobweb, Snowball
Pool 2 (20,000): Ice Elemental, Ice Mine
Pool 3 (4,000): Ice Wand, Snow Spider's Web, Blue Upgrade Stone?!?
Idunno' what that ID for a blue stone is doing there, but it's there. May have been removed since then or something because that would make it about as common as the Snow Spider's Web (an item from a pool is picked randomly as far as I see).
So anyways, depending on how the drop math works for monsters, those pools are either 15%/2%/0.4%, or 86%/11%/0.2%. So the drop chance for the Snow Spider's Web specifically looks to be either 0.13% or 0.06% if the blue stone is still there... or 0.2% or 0.1% if it's not.
Which effectively renders the entire thing hopeless.
Even if you had an army of r1 weave/tailor at your beck and call to assemble into prod parties and godly luck with tailoring completion %, you're looking at a minimum quarter million spiders. What do you get per run, 20? 25? That's over 10,000 mission passes. If quitting after spiders, requiring all passes from sheep (math math) it's over 147,000 shears. Gather speed doesn't work, and there's the extra failure chance on them. Even if we estimate 6 seconds on average per (with movement) and 20% fail, that's over 306 hours of pure sheering paper sheep.
306 hours with a ton of generous estimations that would never work out practically, plus the time for all the runs themselves, and godly luck on the tailor.
There's a reason all existing gloves are leftovers from the old dup. I will never be able to get a pair.
