The skill cap for this is 17. No other crafts required, rank: Recruit. Formula is correct, and of course, HQ is Federation Tekko. You should be able to make this with only some failures about level 11 or 12 if you are taking into account the elemental factors.
anyone have any clue what the cap for this is?? i'm still in the middle of leveling weaving, but i'd like to know when i'll be able to make these (and the HQ)
