Farm spears?

Hi,

Anyone know a good place in EOTN to farm for spears?
I'm perticularly looking to farm a Serrated spear.
I've had them drop whilst farming Destroyer Cores but they're always white

Thanks

Cathedral of Flames (Doomlore Shrine), go there and you gone find lot's of runners(2k or 2.5k) buy some keys . Don't forget to take the quest to (1,5k reward).

Thanks I'll give it a whirl.
