You should make arso undouseable to prevent multiple Arsos from killing each other.
If you douse an arso it should say that your target can't be doused because they're also an arso.
This would be a very minor but important buff imo for multiple arsos to be able to work together.
This change can be justified since SKs can't kill each other,
WWs are unique and even mafias aren't able to unless witched/transed.
So why should arsos, the weakest Killing role, be able to kill each other?
