The Evolution QM
Poison Qi doesn't completely repel predators. It just makes them less likely to attackYeah, attracting predators is actually something we want to do, they're a good source of food.
There's not really much reason to deposit far from our lair if we can't attract a ??? Predator. The food from the predator is the main compensation for the higher DC.
It's possible that not having gunk near our lair means there's lesson chance of attracting/empowering on a bad event, but it's kind of a side benefit and not necessarily worth the higher progress required by itself.
