This suggestion is not for now, but for whenever the perception fix gets implemented. The basic bow, made from a branch and some string, would work, but have a silly-low draw weight and probably wear out quickly. You could probably use them for hunting rabbits or chickens, but taking a deer with a bow made from a bent branch is fairly unlikely. Especially a bent fir branch. The ranger bow works on an game-balance perspective, but the idea that somehow adding steel and silk to a bow is going to make a better bow is pretty unrealistic.
How about these two upper level bows -- (all times are RL)
-- Long bow --
Cut down a log. A Bowyer can process a log into a single longbow stave with a 50% chance of success. Then the staves go into a tanning tub, with water, and they sit there for 24 hours. After 24 hours, they can be pulled out and worked into an unfinished staves, with a chance of failure again. Left alone in the tub for 48 hours, they rot and become nothing.
unfinished finished staves must be placed on a drying rack for 24 hours. Leaving them longer is not dangerous. After they are dry, they can be worked again into semi-finished staves, then back into the tubs for a further 24 hours. Again, leaving them for more than 48 hours causes them to rot. After the semi-finished staves are fully soaked, they can be pulled out and processed into finished staves. Finished staves must be dried, then combined with horn/tusk, wax, and string (horn/tusk is for the nocks, wax is for weather-proofing. And a nice shine.) result -- One longbow.
-- Composite bow --
This would be more difficult than the long bow, but the basic tub method would be the same. However, for composite bows, the bow maker would need tusk/antler lathes and sinew (new item) each time the stave is worked on. Tusk/Antler Lathes would be produced from tusk/antler by a bowyer with composite bowmaking...Each attempt would have a chance of success based on the industry-nature slider. Sinew would have to be implemented...maybe processed from steak?
Anyway, these bows would represent a respectable amount of work on the part of the bowyer, giving marksman users a Simple Bow -> Long Bow -> Composite Bow chain of options, similar to the Melee user`s Stone Axe -> Militia Sword -> Soldier Sword -> B12 Axe.
Also interesting about this is that the melee users are dependent on Industry, while the Marksmanship users would be dependent on Nature.
What you think?
