Rene cannot change the vampire plugin. The vampire plugin belongs to another group of devs and if you wish for something to be added to the plugin, talk to them. And before you ask, no we will not help you find the devs. That is not our job as we are not associated with them, and they are not associated with New Heaven.
As for the werewolf plugin, we could make some edits to it. However, based on what you have previously suggested, if we make an "instant death weapon" for werewolves, we would also have to add one for vampires, which we cannot do, as I previously mentioned above.
Also, I am a little confused about your argument here. You say that the wooden stick is already too powerful, seeing how it 2-3 hits players, but then you argue about adding an even more powerful weapon.
However, this ultimately is not my decision, it is Frost and Rene's. They will respond to your argument in the future. Thank you for making a suggestion.
