additional note on monsters rooting around your stuff: animals could be attracted to food. then youd end up with a bear rooting around that corner you’ve been throwing all your offal in.
my friend suggested monsters be attracted to gold. maybeas you amass larger amounts of treasure you end up increasing your chances of being attacked by something really nasty. like after you get x amount of treasure a dragon can smell it and hes like WHATS UP MOTHERFUCKER LETS DO THIS GIMME YOUR GOLD
you could even set up like… traps and stuff to defend your massive treasure horde.
