here's the other thing about it. I was 93.0 when i crafted it. Wearing +2 in gear, and i Had adv. support on, Not sure if you can get skillup in the range with +stats on but I was realistically at 98cloth when i did the synth and i got skillup. So this is definitely a possibility to skillup, but that also means having to camp arachne all the time to get webs. (good thing arachne is unusual and 2webs = 3 threads lol)
