If I am summoned after using a soapstone, what do I have to do "Fulfill my duty"? I think it's after you kill a boss you get "Duty fulfilled" and return to your own world, but what if we don't kill a boss together, is it on a time limit? Do I help kill everything in an area, or just follow him around eternally? Edit- how do I get a white sign soapstone? I have a small one, what's the difference?
