3 characters in bow on Emerald Island when you start there . . 3 points at the test brazier, 5 points from the well in front of the inn and 3 horseshoes. You obviously did not check all the dwelllings on EI the first time. The expert bow teacher (me) lives in an apartment behind the arms dealer there.As soon as you finish saving the 7 dearves, the dwarf king will give you the key to EI. Talk to the lady in the village who sold you membership in the water guild about how to use it (the key).
Hope this helps
