After listening to the recent Mainframes on Lethality and Do Your MECHANICS Matter?—and btw if you aren’t a Patreon supporter, I encourage you to become one at whatever level works best for you, because that there Patreon is packed to the Gilhelms with useful and inspiring GM shtuff—I had this idea for encouraging both Lethality play and just in general a sense of faster play.
Minimizing all other complex dice interaction mechanics, insert this one across the board:
Speedplay Rule 1: If PC or GM rolls the max on a D6 Weapon Effort, D8 Magic Effort, or D12 Ultimate Effort, consider the task completely fulfilled, no matter how many more Hitpoints or Hearts were left to deal with. D4 Basic Effort continues to work as normal.
Optional Rule 2: (For a Fate/DW mixed success vibe) When Rolling a 1 for WE, ME, or UE, treat as a “Yes, But” or “Success at a Cost” type of success. D4 Basic Effort continues to work as normal.
Now obviously this may add an extra layer of complexity if you are tacking it onto to an existing game with a ton of involved Loot—which is why that preamble about cutting out a lot of other dice related game effects. And it can be a big craziness when the dice start dropping players and badguys willynilly. (But honestly that’s where shtuff gets awesome… when there’s a sense of real danger to avoid, react to, and recover from!)
Effectively, it adds the possibility of “critting” on your Effort rolls. And requires the GM to be very agile in their prep and improv.
So this may work better for new games, one shots, and Modern genres where Lethality is expected to be high and Physical Loot Drops low. Another way this Rule could be useful is in defining a Status which may be temporarily assigned to a Boss Monster (Wrath of the Blood God) or to a PC (Jason Bourne Mode…Activate!).
I’m thinking of plopping this into a one shot real soon.
