In-game description
| “ | Shortbows were the first bows to be developed, although they were not called such. This is more of a default term that refers to anything which is not a longbow. Shortbow staves are about 5 feet long on the average. This shortbow is the rival of any of the larger bows. The magic inherent within it, whether from the wood or the spellcasting of a mage, makes this bow more accurate and damaging than a normal bow. | ” |
