To add onto this I've decided to help fill the rest of OP's wishlist for Luminary grinding. My main focus is selling for a profit or making extremely cheap items. Be sure to stock up on a TON of shards, as making a luminary for just one class can use over 14k shards of one element.
- CRP
31-40: Oak Lumber is the cheapest option here.
41-50: Rosewood Lumber is probably the best choice for using Shards. Depending on your server prices, a profitable choice is Spruce lumber, though it uses Crystals instead of Shards.
- BSM
31-40: Mythril Rivets is a good choice if you buy the ingots from the Amalj'aa. Mythril ingots would probably be more profitable at a cost of less synths per stack. Ingot synth also uses 1 less shard.
41-50: Cobalt Ingot like above.
- ARM
31-40: Refer to 31-40 BSM.
41-50: Refer to 41-50 BSM.
- GSM
31-40: Like BSM and ARM, Mythril Ingot is a safe choice. Some alternatives are Heliodor, Amethyst, Goshenite, Peridot, Aquamarine, and Garnet. These only need one of the raw version and may be surprisingly cheap on the MB.
41-50: Electrum Ingots are a safe choice here. If the MB is willing try out Zircon, Turquoise, Rubellite, Amber, Tourmaline, and Spinel.
- LTW
31-40: Best choices are Boar Leather and Peiste Leather.
41-50: Raptor Leather is probably the best option. Dodore Leather may be cheaper depending on prices as it uses a crystal.
- WVR
31-40: Linen Yarn into Undyed Linen is a great option. Woolen Yarn into Undyed Wool can be considered if prices are taken into consideration.
41-50: No great choices here. Undyed Felt can be expensive but is one of the few crafts that stack for this level range, not counting starred recipes.
- ALC
31-40: Blinding Potion is the best option here. You can buy all the materials from the Kobold Beast Tribe Vendor.
41-50: Unfortunately you cannot get Ochu vines from a vendor. Despite that Potent Blinding Potions looks like the cheapest option here.
- CUL
31-40: Cream Cheese is a cheap craft. Simply make Sweet Cream from vendor'd Buffalo Milk and buy the Night Milk from the Sahagin Beast Tribe Vendor.
41-50: Thanks to the Moonfire event, Rolanberry Cheese is a very cheap craft to make right now! Buy the Night Milk from the Sahagins.
I hope this helps!
