Bane

The Banes are a group of weapons, notable in that they do double damage to a specific group of monsters. They are generally considered to be worthless for most purposes, since they reduce the probability of receiving a more useful artifact.

Dragonslayer

This unaligned broadsword deals double damage against all Dragons, as well as has +d5 to hit them.

Giantslayer

This neutral long sword does +d5 to hit and double damage against all H, giant mummies, zombies, but not ettins or titans.

Ogresmasher

This unaligned war hammer confers +d5 to hit and double damage against ogres.

Sting

This chaotic elven dagger provides +d5 to hit, and does double damage to orcs and no other. It also provides the warning intrinsic against orcs, and cuts through spider-webs.

Orcrist

Big brother to Sting, this elven broadsword is chaotically aligned, and gives a +d5 to hit and double damage only against orcs. Sting and Orcrist may be created by #name'ing a single elven dagger or broadsword.

Trollsbane

This does double damage to all T, troll mummies, and troll zombies, and +d5 to-hit.
