When wielding Sting, you should be able to untrap adjacent webs and monsters stuck in those webs with 100% success.

You can’t name Sting until you have killed a spider. (This could be limited to after you kill a giant spider, but by that point most players probably don’t need Sting.)

When the player kills a giant spider with an elven dagger and Sting has not yet been created, the dagger is converted into Sting automatically. Sting is made of rustproof steel, instead of wood (this would be tricky to do because of base items; you would still want to be able to create it by naming an elven dagger, but Sting in the lore is made of steel or at least metal, not wood). Sting has bonuses versus spiders, in addition to its bonuses against orcs.

You can dual wield Sting and Orcrist; this gives an even bigger damage bonus against orcish monsters.

When “Sting cuts through a web!”, the web is destroyed. Currently it only allows you to escape the web in 1 turn and does not destroy it.
