/slap neiko, the reason its at 102 is because since the sabotans cap at 100, and a sither is at 99 in skill, it will be harder to get skill up on a 100 cap than 102 cap. craft skills dont go past 100
I still smell BS. You will stop recieving skillups on this at lvl 100 regardless of any craft support/items. How then can anybody claim that this skill would "theoretically" cap at 102? The best evidence you could provide would be along the lines of, "It seemed like I failed more often than I should have while skilling up on these at 99," which is complete conjecture.
There are 2 guild items that you can earn to get you an extra +2 to smithing skill (or +2 to any other skill, depending upon what guild you are in... I think?)
So... even though having Smithing skill at 102 is highly improbable (due to excessive time/gil/difficulty involved) it is definately possible.
102 smithing still doesnt make sense, because that figure is what the synth should cap your skill at.... theres no guild test to go beyond 100, is there? unless the synth uses theoretical, unattainable skill requirements to make it more difficult than a 100 cap synth
Don't forget the additional benefits from the Synthesis Imagery Support. Plus all the guild items to up your skill, it is most certainly possible to accomplish.
