Level 4 Alchemy Bundle will guarantee you a Crafted Component. Only way to obtain this bundle is to buy it in La Victoire or through the MP.
Bahamut's Fire,
Devil Imp's Claw,
Enchanted Water,
Candy Mountain,
Succubus Kiss,
Red Mercury,
Angel Imp's Feather,
Ahuizhotl's tail-hand, are Component Formula's which will fail a lot, but its something to consider if the others are a bit to pricey for you.
Deluxe Bone Mask is very easy, decent resell, only downside is the Level 6 Ogre Bone it requires, so you'll have to hire someone to craft that for you, unless you buy it straight from the MP.
Dragon's Pride Armor is a bit inflated and is something to consider going after, granted if you can get the other items at a nice price.
Meat Club is basically something you can make if you take your time and gather the 30 Components it needs, not much resell value though.
Autopsy Scar should be fun and easy if you play zOMG! a lot.
White Drome Egg would be very simple if it wasn't for the very hard-to-find Stolen Mesozois DNA, if you have one or manage to get a good deal on it grab it!
Cuttlescythe is a nice and easy one, though you will have to either buy the Orge Bone or hire someone to craft it for you, after you gather all the components of course.
Crown of the Faceless Ruler is very inflated, if you're lucky to get all the Masks it requires it'll be good for you, though you will have to hire someone to craft the Plague Virus for you.
Regalinovo is the one of the best ones to make, resell value isn't so bad either.
Longer Langer is a great choice, I mean, how doesn't want a pet Dragon.
Black Neko Cosplay equires many 'cat' related items, can be fairly easy to gather them all, won't get a lot of resell value, but its not as bad as it could be.
