If you would rather pick off monsters from a safe distance, you will

Several kinds of ammunition, such as javelins, are effective when simply 
thrown; other kinds require you to wield an appropriate device to 
inflict worthwhile damage. Ammunition has only one "plus" value, which 
affects both accuracy and damage. If you have ammunition suitable for 
what you are wielding, the 'f' command will choose the first lot in your 
inventory, or you can use the 't' command to throw anything. If you are

The 'f' command fires a piece of ammunition, chosen from lots suitable
for your weapon and defaulting to your preferred lot (or "quiver"),
typically the last lot you fired. Use the '(' command if you want to
change your quiver without firing. Use the 't' command to throw
anything.
Regardless of their mnemonics, if you are using the right kind of hand
weapon both 'f' and 't' will make you "shoot" the ammunition.
Otherwise, you will "throw" it. At times it is also sensible to throw
