Available for a total of 200gc in The Bifrost is the Level 2 Alchemy Bundle. This bundle contains a modified level 2 formula, and the necessary components, to help you gain experience fast in alchemy. If you don't mind spending money. The formula included in this bundle is modified to have a 100% chance of success, for a guarantee of 10% of the experience points you will need to level up. This bundle can be found, very rarely, in the Alchemy Fusion Cache.
Pantz's Picks
At level 2 your options on formulae are somewhat more limited than your options from level 1. Though bear in mind you can use level 1 formulae to gain experience at level 2, it'll just take twice as many of them.
● Clam Shell Hat: The most difficult part of this formula is collecting the clam shell purses. Those can be found in Back Alley Grab Bags and Alchemy Fusion Caches, not to mention any lingering recipes from zOMG. Once you get those, the crafting cost and the gold shop components should be simple enough to acquire. It has a low crafting cost and very high success chance.
● Melodic Triangular Beat Style: The hardest part of this formula to acquire is the 1bil crafting cost. The rest of this very high success formula comes from caches or fishing. Those electric jellies might present a pain.
● Overgrown Kudzu: If you made Titan's Legacy Seeds for level 1 you can use them here. Though those 150 zOMG caches might be a bit much.
● Pancake Top Hat: It needs one amethyst caches and buying a lot of goldshop items. This formula has a low crafting cost and a very high success chance, arguably one of the most cache efficient formulas for level 2.
● Spring Cherry Blossom: Only hurdle here is the 100mil (10 plat) crafting cost. The rest of this formula is entirely from caches. Has a very high success rate.
● Summer Sunflowers: 100mil (10 plat) crafting cost is a major hurdle to crafting this formula. Sunflowers and Grasshoppers are the next most difficult part unless you love Towns 1 or 2. The rest comes from caches.
● Tsunami KO Shirts: Low cost to craft and very high success chance makes this one of the easier formulas to craft so long as you have enough ink.
● [Animal] Practitioner of Black Arts: The 100mil (10 plat) crafting cost and fireflies are the harder pieces to acquire in this formula, the rest comes from caches, but it has a very high success chance.
● [Animal] Spring Cherry Blossom: Only hurdle here is the 100mil (10 plat) crafting cost. The rest of this formula is entirely from caches. Has a very high success rate.
● [Animal] Summer Sunflowers: 100mil (10 plat) crafting cost is a major hurdle to crafting this formula. Sunflowers and Grasshoppers are the next most difficult part unless you love towns1/2. The rest comes from caches.
● Minotaur Horn: It has a very low success chance but a low crafting cost, uses only cache components and has a variety of uses at later levels.
