Game Mechanics A Time Gain Related Mission?

I like lootruning fruma, I used to only LR the silent expanse, but Fruma is alot nicer, however some of these caves are long, like really long and while Fruma does increase the base time gain to 5 minutes, however one of my favorite play styles is kinda gutted by this. as splunk kinda kills red run's consistency. I feel like a challenge(s) that can increase your time can be useful, they shouldn't be like too free. Maybe like Killing a radiant mob, or getting curses that increase your time by a small amount, so it not worth to go out of your way to grind, could make red runs, especially in fruma a bit more consistent.
