I'm guessing you'd have some tradeable equips from your dual blade that you could use so maybe try get a decent cane? If you don't plan on maining it then I'd probably suggest a revolution cane from the red shop with +8 Atk scrolls dropped on it until the slots are used and pray you get lucky.
The best thing to do for any character when you have limited funding is to fund in moderation. 6% luk doesn't seem like a lot but when you buy 5 6% items, it adds up faster. Get 6% tempest items if you don't have better. Tempest ring, shoulder, belt, pendant. That's 24% luk right there which helps tremendously. % earrings are abnormally cheap because of crafting. Especially half earrings, you can get 12% luk earrings for maybe 200m in Nova, probably around that if not cheaper in Bera. That would put you at 36% luk, and already an amazing start.
Not sure what you have from your DB. But just remember, the key is balance. You can have a lot of atk and no % luk and be really weak... or a lot of % luk and no atk and be weak. So make sure you're also working on slowly upgrading your atk while you upgrade your % luk equips.
@ChauSon: ok then, well I'd work on getting a scrolled empress cane so you can upgrade it to sweet water when you have the opportunity. 600m won't get you too far but I think you should be able to get the cane, gloves, shoes, hat, and overall from the emp set and use epic pot scrolls from the red shop on them, or scroll the cane. It might be useful to farm bingo on mules to help with getting more red coins since you don't have much funds atm.
EDIT: if you don't want to go the empress route, you could maybe try to get some purple senior equips with % luk from monster park extreme. Tempest equips are also pretty good, but they seem to be inflating a bit.
@ChauSon: Something cheap and effective would be either loveless or empress. They're not overly pricey, and you can toss some 50% +8 atks on there for the time being, even if it's horrible scrolled it's not a bad base attack to hold you off for an endgame.
As the guy above mentioned. % Luk from senior items are good too. That would cover your shoes, hat, overall, and gloves if you don't have any. You can get 4% pretty easy, and 6% if you put in a little effort, and you don't even have to pay for it, just train your character and loot a lot. 4% on another 4 pieces is another 16% luk. That's 50% luk with only like 400m (Depending on price of Tempest items)
@Spyro what about equips after the purple senior stuff? would like pirate top and bottom (lvl 80?90?) be good after that if they had like 9% luk on them?[/quote]
Yes, without a doubt. Top/bottom set is always better than overall. There is no case which overall is superior as of now, not to say it may not change later on with future advancements, with Maple going the direction it's going. I would personally go with Pirate top/bottom because of looks....but ofa isn't bad either. The point is it's a 3rd tier top and bottom set.
@ChauSon: No problem. That's my personal experiences, that's how I fund all my mules/noobs. I actually had like 2b recently and decided to fund my Zero and my Drk, so I bought a bunch of 6% str tempest stuff, then started working out to other stuff.
