There is now a vendor that sells oak shields among a few others in Aht Urhgan Whitegate. His name is Saluhwa at H-6. Oak Shield was selling for 15,600 gil.
this is crazy.. i lost lot of money from making them to the guild.. 50k for iron sheet for one stack in my sever...then 5680g for 1 oak lumber from the woodguild. i broke more than 8 lumbers for just making 3 shield T-T.
i think the smithing affect my craft alot. Lv. 45 wood and lv 5 smith atm >~<
