Arrow/Bolt head = 24gc (1 iron bar @35gc + 1FE @3.5gc +1WE @6gc)/2
Yew = 3gc
Feather = 15gc (weather falcon or hawk, same price)
Air Essence = 8gc
This gives the cost of PK arrows/bolts at 50gc each.
These prices for ingredients can be used to figure out prices of other higher levels of arrows as well.
