Boss souls are very useful and you will only get them after defeating certain powerful boss in an area. Each great soul can be transposed into two different items, usually weapons, but sometimes spells or rings.

The Nerd Stash: “Whether you’re here to gloat about your victories or to see what the fuss is about, we present to you the hardest bosses in the Souls series.”
Dark Souls 3 is easily the most replayable game in the Dark Souls Series. But, is the game good enough to spend nearly 10 hours killing Silver Knights alone?
These games bore me to tears. I don’t mind the difficulty it’s just the constant killing the same enemies over every time you rest that makes it so monotonous
