For instance, this bow by itself provides 4 STR and 4 AGI, plus +40% HIT (the big deal about bows)
But with the dextrous suffix it gives 20 AGI, that scale to 35 on an Archer whose AGI multiplier is 150%, and further boosts HIT by 15%, for a total of 55% hit% + the archer's high base HIT%! not even the most evasive of foes will escape you now! >:^D
