yikes... really? it only takes one mace, a shield and a few poison res meads and maybe a few minutes to take bonemass down without a bow

but ok, some like it the hard way i guess

to the op, it depends on the lvl of the weapon and your skill how long it lasts.
same goea to the lvl 1 club wich goes down fast.

so maybe a little rebalance on this bow might take place

on the other hand - fighting a boss with high pierce resistance using a bow may not work very well
