Flame Grilled Wopper

The Flame Grilled Wopper is the third-to-last object that needs to be crafted in the Age 0 (Stone Age) progression. It requires two Red Cedar Planks, one Shadow Gem, two Charcoal Dust, one Shark Tooth, and one Wopper Mk2 in order to craft it. The crafting recipe can be found in the JEI interface.

Materials Required
1. First, if you haven't found and killed sharks already, you need to make a Strainer Base (found in JEI) and a Dense Survivalist Strainer (which requires a Dense Net, not a just a normal Net. The Dense Net is made with 6 string, not 3. Make sure you have the correct one).

2. You will need red cedar logs to turn into red cedar planks. In order to get red cedar logs, you will need to grow red cedar trees from red cedar saplings. Red cedar saplings are obtained by performing the Totemic ritual called the "Rite of Spring" while you have vanilla saplings nearby. The ritual will transform the vanilla saplings into red cedar saplings.

3. Make a Wopper Mk2. You can find this easily in the JEI interface.

4. You will need charcoal dust as well. For this, take some of the low-grade charcoal that you probably already made (if you haven't made low-grade charcoal yet, place a wooden log into the Clay Kiln from primal_tech, and leave it in there until it becomes low-grade charcoal), and put the low-grade charcoal block into a grindstone (either a manual grindstone or the Horse Power grindstone). From there, take the charcoal and put it into the Mill Stone from Better With Mods (which is covered in a separate Advancement). This will give you charcoal dust.

5. Finally, you will need a Shadow Gem. In order to get a Shadow Gem, you will need to kill shadow creatures from the Abyssalcraft mod, which can be found in any of the various Darklands biomes. You can either follow the temperature map of the pack to find a Darklands biome, or make the Nature's Compass (as detailed in the Advancements) to find one. Once you have located a Darklands biome (of any type), you will have to kill shadow creatures for their drops. There are three types of shadow creatures, which will spawn within any type of Darklands biome, but only within the Darklands biome: - Shadow Creatures are actually the name of the smallest mob, which will drop at least one Shadow Gem Fragment each. Nine Shadow Gem Fragments can be pressed, using the Horse Power Press, into a single Shadow Gem Shard. Therefore, 81 Shadow Gem Fragments will form one full Shadow Gem. - Shadow Monsters are the second, medium-size mob, which will drop at least one Shadow Gem Shard each. Nine Shadow Gem Shards can be pressed into a full Shadow Gem. - Shadow Beasts, which are the largest, extremely dangerous mobs, which have a chance to drop one or more full Shadow Gem each. It is recommend to make a shelter to kill these large ones safely, since it is the fastest (albeit riskiest) method of obtaining Shadow Gems.

Finishing Up
Once all of these items have been obtained, voila! You have a Flame Grilled Wopper! You may want to consider making more than one, as they are handy for early automation of cooking and some smelting processes, and one Flame Grilled Wopper will be consumed by a later Advancement.
