Coach recently shared that martials may regain all SP on a quick rest instead of having unlimited SP out of combat. - Many of my techniques are overpowered or might be spammed if this or a similar rule isn’t applied in your games.
I personally like the idea of not needing to stop the game to rest, but instead SP recharges passively after 5 or 10 minutes without using any. This way players can’t spam SP abilities back to back or just before fights without consequence. But they can use it regularly out of combat without having to track it or stop the game to rest. It should be simple enough that you shouldn’t need to track SP at all out of combat, just know you cant spend more than your SP maximum in a single social or exploration encounter.
You could also do a mix of the two option - a 10 minute rest recharges all SP AND so does going 1 hours without spending any SP.
