Forum:New Feature: WOUNDING
I added a new feature for *hack called Wounding (I have a diff for SlashTHEM, but it can be implemented in other variants as well). A weapon with WOUNDING will "wound" a monster with a 20% probability. If wounded, a monster will "bleed" a certain amount of damage per turn which will eventually lead to its death. In addition, I added a new chaotic longsword artifact with the Wounding feature.
To shamelessly plug my blog, you can find the diff at http://nethackadventure.blogspot.com/2016/09/wounding.html
