Adamant bolts

Adamant bolts can be made using the Smithing skill from an adamantite bar at level 73, producing 10 adamant bolts(unf) per bar. Attaching one feather per bolt with level 61 Fletching, at 7 exp per bolt or 70 experience per set of 10 bolts produces the finished product. Then, bolt tips (made by using a chisel on a cut gem) can be attached to them and subsequently enchanted for different effects. The two gems that can be attached are ruby and diamond, resulting in ruby bolts and diamond bolts. The two bolts previously mentioned only work with an adamant or rune crossbow.
