Putting an earth deleter in zodiacs will not only reduce your sp consumption but turn it into infinite sp if you can DS something in one shot. You'll gain twice the sp per kill that the odins would give because of the wings double card effect. No need for ulles or the odins. Leaving you free to self buff without worrying about the sp cost of those skills.
Given that your new and most likely didn't know about these wings what you did was quite smart. The list of items required to make the wings may seem long but is well worth it. Upgrade to zods and you'll be glad you did.
(I am aware that ToH wings do the same thing but better, but are not practical for new players to obtain)
These prices are subject to change based on current market but should stay around that number as they have over the years. (they have been for at least 4 years and only flux slightly)
I hope these help new folk get established. Besides the zipper bears these are extremely easy to farm they just take longer than thara/hydra in the kills/hour area.
