Best place to farm Power Crystals?

Title. I've got everything else I need from Chief Qualm Guardians, including cards, and they apparently aren't giving me Pieces of Time (I'm one of the Monster Book compensated people, so 2x drop ftw). Any better place to go to?

Sakura cellions? lol

Sadly I can't remember where I hunted mine, I've got about 45 refined...

Good guess it's either Dual Pirates, Skelegons, or Red Wyverns though. lol.

Skelegons = no. I woulda had my quota filled already if it was skeles.

Dual Ghost Pirates on the other hand... I think I might have NPCed all of those *headdesks*

DGP do drop power crystal ores. At a fair rate.

Duals, harps (blue), the blue herb town pirates, qualm monks, qualm chiefs, and vikings are some of the most commonly hunted monsters that drop power crystal ores. I would continue doing qualm chiefs if I were you, at least you get some exp and chances at time pieces.

I usually get a Piece of Time within two hour of killing mobs. But I spent a nice solid 4 hours with 2x drop at Qualm 5 with no Pieces of Time.

I suppose my option aren't looking too good =/

Coolie zombies!

Wait that was two years ago. I remember they dropped fairly often, it might be worth a shot.
