Firebow

Akin to the dire swords, this bow makes its arrows burst into flame, adding 1-6 fire damage to every creature they hit. Each +1 of enchantment on a bow also stretches its range by 10%.

Besides its special power it may carry +1-4 to hit (+1-3 if enchanted with orichalc); every plus adds to both attack and damage rolls, and a magical weapon counts as superior quality when saving against breakage. Magical arms and armor can be enchanted by alchemists using orichalc or by casters of any profession. A caster needs the materials of a minor magic item and a weapon of the finest quality, then one month plus a further month for each spell-like power or +1 conferred, with a 99% chance of success; the finished piece usually sells for at least twice its materials plus 2,000 G.P. per +1. No mortal can enchant anything beyond +4.
