LOL FARMING FOR DRAGOON GEAR (that's funny) (that might've been a mistake but you can't farm for dragoon gear unless you pray fellspawn gives you something besides saytr chow and beast wellingtons) Anyways:

you're only gonna need the boots, hat, and ring

Boots: Prince Viggor in Viggor's Tomb drops these

Hat: King Detritus in Abandoned House

Ring: The Devour in Edge of the Spiral (don't recommend farming for this cause it's a really hard boss; easier to just craft it)

Once you get the VANGUARD gear (the droppable gear) then you can use these to craft the DRAGOON gear which is currently best gear in the game and is worth it

Good Luck :)
