There's a rule, maybe there's more, but there's a rule on the vanilla server that Mod's are told about, but isn't in the rule list. Could someone please add the 'Damaging Traitor buddies will result in a slay' rule to the list? If there's more rules that aren't in the rule list, It'd be nice if those were added aswell. This would be really nice for people new to the server, or even new to TTT in general, and don't know ALL of the rules of the server.
That is a rule. It is considered RDM if enough evidence prevents the conclusion of the instance being cross fire or Lack of knowledge (EX: T tells Ts in T chat about T traps or grenades, a T does not notice and dies). There's a list of rules here yo: http://www.seriousttt.com/threads/a-guide-to-sttt-extended-rules-info-tips-tricks.12605/#post-20582
The single rule under the specific ruled for traitors is no killing t buddies. Think of it this way: Killing is a present tense action verb. Killing does not mean the traitor buddy has to die. Simply damaging them is killing them. For example, if I wrap my hands around your throat so you can't breathe, I would be killing you. If you died then it would be that I killed you. See the difference? Most of the extended rules that are listed are mostly present in the MOTD; with by their inclusion or omission from them. The extended rules mostly give further explanation of the current rules.
Hello Discord, I was the person who slayed you, you had damaged your T buddy with an incend, just because you didn't Kill him you were in the process of "Slowly cooking your buddies alive" That's not cool. But in all seriousness Damaging=Killing
If it negatively impacts gameplay for other players, probably shouldn't do it. That's a good way to live if you don't want slays.
