The Katana 'Aglarang' (8d4) (+0,+0)
The katana is a long blade with only a small disk for a guard. Its hilt is
long enough for two hands, though it could be used with only one hand, and
is usually wrapped in cloth or leather. The art of forging such swords is
largely unknown in this part of Middle-earth, and such weapons are
typically imported from distant lands.
An utterly perfect, cleanly chiselled sword, with a edge that effortlessly
slices rock and bone, and spells to render the wearer lithe and nimble.
It is combat incarnate.
It can be wielded two-handed. It increases your dexterity, ability to
tunnel and speed by 5. It sustains your dexterity. It cannot be
harmed by acid, cold, lightning or fire.
