Unless there is some history or Waris doing it or Waris is a total prick in game. Saccing is kinda lame.

Just starts a huge cycle of shit. Sportmanship and all that.

You can keep to good/evil role without trying to demoralize the player behind the char.

Basically though it just makes a angry skilled duergar whom when he kills the next smuck will vent a bit and some newb is gonna pay the price. Might lose another as a side effect.

GOod logs though, I enjoy reading them.
