Base price
Description
This number is determining the value of item in NPC's eyes. In case of destroyable items the more damaged it is the lesser you can get for it. Each point of detoration is decreasing the value of item by 0,5%, each point of used durability is also decreasing the value by 0,5%.
Items that can't be repaired are having base price reduced to 1$.
Examples:
The BB Gun has a base worth of 200$. If your weapon is 6/100 its base prise its 106$.
The BB Gun has a base worth of 200$. If your weapon is 79/0 its base price is 21$.
The BB Gun has a base worth of 200$. If its beyond repair its base price is 1$.
Note: While selling items to NPC's not only base price is being checked. The game engine is also checking your barter skill, and quite possible some other thingies. All together this is determining the actual ingame price of item.
Note: You shoudn't care too much about base price of items when bartering with other players.
