You have to go back to the screen just before the jump you made for the blue flower . In the top right corner there is a baracade that you can destroy with the axe. you go inside and use the sounding stones to get around the goblins. Open boxes and chests inside to get black powder. If spotted you will be put back outside with some health lost. eat and keep searching until you get what you need.can some one talk me how to get black powder?
