If you're REALLY lazy, and have a lot of dominion points with nothing to spend them on, you can get some pretty high base dmg daggers from the dominion NPC in grauberg. I got a DMG+8 (making the total 43, which is the dmg rating on kila+2s) crit dmg+6% one the other day for my COR, and that was only like the third dagger I bought from him. That would make a reasonably good mainhand weapon for a DNC while you're stuck in magian hell, especially if you've got razed ruins to make good use of the crit dmg.
As for other choices, I do a ton of soloing/tanking so i opted for an AGI/eva kila+2 for my mainhand and they are VERY easy to make. I finished mine in less than a week.
For offhand I have an auric dagger and a 2-4 parazonium that I switch between depending on the situation, I usually only use the parazonium when I'm doing a lot of healing (and therefore can't use saber dance) and still want to toss out a WS every now and then. People who say a DNC can't main heal an abyssea alliance are ignorant asshats =P. Now that I have it though, I'm kinda lamenting all the time and effort I spent on making it, because it sees so litle use. I mostly use auric as my offhand, because I really really really really really don't want to have to make another magian weapon, and because it looks cool (I'm vain like that ~_^) I'm sure there are better things to use, but I'm content with what I have for now. Droprate is pretty high for auric, and all you need is a BLM friend or two to help you kill the NM. (Got mine on first kill with Me on RNG, PLD and BLM friends, super easy and relatively short fight, my RNG was basically overkill)
Every now and then I toss on Auric mainhand and para+2 offhand for the novelty, but really, there are better, easier to obtain combos than that. It's mostly just for goofing off.
