Rules or Guidelines?
I'll be running this basically using Call of Cthulhu 7e.
Note that for over forty years, I have treated every set of RPG rules as guidelines. Especially for Play-by-Post, I tend to streamline things somewhat to minimize how many interactions it takes to resolve something, especially in combat/action. I always try to give the player characters a square deal and most of the breaks.
In this story, I'm going to allow Luck spends as written and I'll give Pushes a try. But I'll need you to call the Luck spend or Push attempt when you post your dice results. There won't be a separate post to foreshadow failure for a Push; just figure it will be very bad.
Also, if you don't roll damage when succeeding at a combat roll, I'll roll it for you, rather than asking for another post. Likewise with Sanity checks, if you fail one and don't roll the stated loss, I'll roll it for you.
I'm not dealing with bonus/penalty dice. I'll adjust the needed success level in such cases.
Critical Success
A roll of 01 means that something beneficial occurs beyond achieving the goal. The nature of the good fortune is up to the Keeper. In combat, for example, a critical success means the attacker has hit a vulnerable spot and causes maximum damage.
Fumble
A roll of 96-100 means that something worse than a straight failure has occurred. The nature of the misfortune is at the Keeper’s discretion. I'm not going to differentiate between fumbles based on whether the success level is above or below 50. I've got enough to keep in mind.
Most importantly, keep this in mind (from the 7e rules): The Keeper’s Decision is Final. I usually try to explain my process in any case I think might be unclear. You can ask me about it if you feel I've overlooked something, but I do not like rules lawyering. I want the story to flow as best it can in this format.
