These are mostly unchanged from NetHack.

Thrown Weapon Modifiers

  1. Can get weapon quality modifiers
  2. Can be mythic or legendary

A dart, shuriken or boomerang that hits a monster may be destroyed by the hit. A blessed one survives unless the monster's passive effect damages it. For one that is not blessed, against a monster without such an effect, take its erosion minus its enchantment: at 0 it breaks 5% of the time, at 1 about 6%, at 2 it is 50%, at 3 about 67%, rising from there, and below 0 a little less than 5%. A javelin, throwing axe or aklys has no such chance.
