Luk Crystal Ores

Does anyone know a good place to farm luk crystal ores? Preferably somewhere I can one hit kill with a level 99 hermit or a 73 blaze wizard. Any suggestions are welcome though. Thank you!

Among the mobs listed, I find Homunculus to be potentially crowded, you might want to give it a shot.

I remember finding a lot when I trained on Jr. Grupins and Grupins.

Gobies perhaps? get some exp in the process as well ~
