roleplay peacegiver

[Zondartul]

Hello, haven't been in DX for long, couldn't find CD.
As allways I have no idea if this is the right forum for that, but anyway I'm requesting a summonable and map-placeable actor that makes sure you can switch between two teams by putting command in chat, like -switchtocombat and -switchtopeace (to ensure you don't accedently enter them while talking). In team combat you can kill and be killed, in team peace you can't be killed and can't kill.
Posting this here just in case I wont make the same thing in few hours.

Edit: What event is when player says something in chat?
