You know how it goes... You kill wolves and kobolds and bears... you get loot. You kill more generic denizens of your fantasy world... you get more loot. You get stronger... you kill more mobs... you get more loot. How powerful do you want to be? How much of the grind can you endure?
If your loot drops... don't stop there! All loot has a chance to drop at a number of rarities, increasing its stat contribution!
Rumor has it that another rarity exists...
