Have any bows or just the dagger?
I would go for Plagiarism in a few more job levels - as soon as I could get it.
Maybe just hunt around in Toy Factory or something until then, unless you do have a bow. I guess Siroma are supposed to be good, too, now?
I'm not sure what a recommended level for those would be, or if they really are good for some quick job exp.
(Even a bow from an NPC shop would probably suffice if you'd rather use Double Strafing on things until you get Plagiarism.)
Then... copy Turn Undead for Ancient Mummies (Int, Luk, Flee), Bowling Bash for Skellington or the Valley of Gyoll or wherever you find it fitting (Dex, Vit, Agi if preferred for a little Flee) - whatever you can survive through at your level. If you can manage IC and decent MAtk, Storm Gust in Prison would work for a little while, too.
Bow would be better for Bowling Bash if you don't mind not having a shield and have good armor, since you can just equip a few arrows and change your attack element without needing an endow (@Demon maps especially, unless you have someone to Aspersio you) and not worry about putting points into both Str for power and Dex for hit.
There are other suggestions in the Rogue/Stalker thread, but I understand not wanting to dig through it since it could really use some index work for convenience.
If you don't even want to use a skill and just want to dagger shadow-property things around for a while, you can also copy Aspersio yourself and just stab away until you need to take more drastic measures for better exp.
