Master Bowman

The art of archery relies as much on strength as it does skill.  When armed with a mastercrafted bow* you may add your str bonus to your dex bonus when calculating your hit and damage bonuses.

*Mastecrafted bows are tailor made for the individual archer by a master bowyer and cost 10 times the normal amount per +1 of str bonus (eg +1 str longbow costs 500gp, +2 str bonus longbow 1,000gp etc).
