The Kasatha are a secretive Society of offworlders. Dharkantia is not an exception on secrecy. Her family has stayed on world and are part of a vast information network for Kasatha who come to Golorian.
During their time here they had gained many non-Kasathian friends. One of which was a priest by the name of Matthias. He wasn't all right in the head many thought. He was excentric and took a liking to the young Dharkantia. Her youth was normally filled with drills, teaching her the fighting techniques of her people and the sporadic visits from "Uncle Matthias". He told her of many of his travels and the far off lands he had seen. This filled her with a passion to do the same. Her parents on the other hand denied it. She was to young.
Now she was older and her mother made her a deal. "Make a bow that takes your strength to pull and I will allow you to travel." So now she is searching for a job to gather the money needed to do such a task.
During your travels, with first the team and then in the lands searching for a halfling lass's family your work on your bow was slow and tedious... it was only when you crossed the 'line' into Isgar on your way to Druma when a large stag burst forth from the underbrush, followed by three wolves. Before you even had time to move the stag spun about goring the first of the wolves.
You could see however the stag was on its last moments, entrails dripped from underneath it as another one of the wolves got too close to the creatures horn... the third wolf managed to jerk the front hoof of the great stag back and it toppled forward jerking once but then its movements stopped. The wolf spun to growl at you until a sharp stone from your halfling companions sling struck it in the chest and it yelped darting away into the underbrush leaving you with the kills.
Inspiration struck on your work on the bow, the wood you were using was good and solid but for some reason it just seemed to lack tensile strength to match your powerful draw... but the stags rack of antlers... gleamed in the light, the curvature of its horns matched the designed curvature of your bow, and with careful application of the carved horn slid along the brace of your bow you were able to strengthen it greatly... plus it certainly looks exotically nicer.
(for the purposes of its creation, treat the bow as a MW Composite longbow with your choosing of its strength bonus. Although note, you must pay the appropriate strength bonus in the cost of your creating it. Take whatver is the total cost of the weapon and divide it by 2.
I believe you are probabaly wanting the +3 bonus so the total cost estimated would be 300 (MW) + 100 (Composite Long bow), + 300 (+3 STR to damage) so 700/2 = 350 gp to create the bow. It will also have additional hardness and hp, but i havent decided how much yet)
