try farm Stone in Zokztda Ruin. I always sold the pebble and get spina in short time.

 

if you're farmer with low atk, i suggest try farming hematite (underground ruin) or damascus ore (lutaros or darkanon)
both are necessary for refining and has range from 30-50k (hematite) and 40-70k (damascus ore)

if you have more matk,
you can try farm dust gemstone and dirty antique (cursed cock at magic waste site)
dust gemstone is 10 pts mana mats (similiar with sumshell, so it can be sold at 50k/stk)
while dirty antique, can be sold at 250k per stk or open it by yourself for time warp watch (10m/20m/50m)

otherwise, just stick at NC
or you could be refiner like me, for easier spina making
