Golems also also a frequent spawn in Ceo Island, but then again they love to rape people. Also you spelled Dorren's wrong.
For Stone Imps, put one of their pieces on the dungeon. The last time I ran normal there was like only five.
Dorren's Request >>>>>>>>>> Ceo island.
Dorrens are weaker, infinte spawn, and they come at your pace.
Also Chisuke, I think you should stress how important the brionac can be for this skill.
Especially r5+ when they want you to use so snow crystals. =x
