How to get more swords and spears consistently?

Hi,

Wylder main here, still in beginner phase clocking in around 50 hours.

Now don't get me wrong, greatswords are great and I do enjoy the variety they provide but I'm getting kinda tired of them at this point.

Back in the main game I thoroughly enjoyed powerstance straight swords and especially spears movesets. 50 hours later, I've had only 2 runs with double swords and I'm yet to have a single run with two (decent) spears.

Any way to increase the possibility?

Preferably without using the dormant power relic, because I don't even have one, and even if I do, it's kind of a waste no?

If I find some basic sword/spear and carry it and kill few field bosses, does that secretly raise the chance of finding them in boss drops? Is that a hidden mechanic?
