Alright, so, the new jeweled caches have been out awhile, I've seen enough data to feel able to make the suggestions I've had stewing in my mind since their release.
As a note, this suggestion post will be number/code/math heavy to some extent. My suggestion is to make a potential effort based route for the new jeweled caches. Just bear with me here, as I do believe this is pretty balanced.
So, first off...
Base Cache is this:
This results in a generic Philosopher's Cache, which is a RIG bag with slanted rarity. Earlier this week I had some time around work to take a look at the trends and such for the various jeweled caches that come from the normal Cache now, and this is what I found:
Quote:
Data taken at about 11 PM Pacific on May 8th.
A normal cache is currently going for Average Buy Price: 183,916g -2%
Other Caches:
Philosopher's Cache: Sapphire (Any) Average Buy Price: 117,338g -2%
Philosopher's Cache: Emerald (Any) Average Buy Price: 112,694g -2%
Philosopher's Cache: Amethyst (Any) Average Buy Price: 130,444g -0%
Philosopher's Cache: Topaz (Any) Average Buy Price: 138,242g -3%
Philosopher's Cache: Garnet (Any) Average Buy Price: 158,198g -11%
Philosopher's Cache: Ruby (Any) Average Buy Price: 160,975g -4%
Philosopher's Cache: Aquamarine (Any) Average Buy Price: 226,060g -1%
Philosopher's Cache: Diamond (Any) Average Buy Price: 243,332g -2%
Philosopher's Cache: Gold (Any) Average Buy Price: 596,277g -1% (Note that the average increased from 500k before starting to level out again)
Philosopher's Cache: Platinum (Any) Average Buy Price: 1,590,780g -8% (Not a very large sample, but the trend has been somewhat stable at 1.2 mil+)
This leaves us with 3 main groups: The jewels that are cheaper than the base cache, the jewels that are around the same price or slightly higher than the base cache, and the jewels that are far more expensive than the base cache. Arguably there could be 4 groups, since Gold and Platinum have a huge price gap, but I'll get to that later.
Based on the above data, which suggests that the lower priced ones were more common (and the number of listings backs this up, along with commentary I've read around the forums), I have a suggested set of formulas based on effort. The guaranteed result that you want does not come without a bit of a price though, as you'll see.
Suggestions for the first group
The following formulas would be sold in Bifrost:
Formula 1: Philosopher's Cache: Sapphire
Formula 1: Philosopher's Cache: Emerald
Formula 1: Philosopher's Cache: Amethyst
Formula 1: Philosopher's Cache: Topaz
Formula 1: Philosopher's Cache: Garnet
Formula 1: Philosopher's Cache: Ruby
Formula Cost: 20,000 gold
Formula Requirements:
The idea is that there is a higher initial gold cost and higher crafting cost with the same low success rate, but a slight decrease in the requirements. As these caches are the most common from a base Philosopher's Cache, they are worth less, and thus would cost a bit less in terms of components. However, since you get a direct choice, the gold cost increases to compensate.
Suggestions for the second group
The following formulas would be sold in Bifrost:
Formula 2: Philosopher's Cache: Aquamarine
Formula 2: Philosopher's Cache: Diamond
Formula Cost: 30,000 gold
Formula Requirements:
The idea here being that since these prices are around the base Philosopher's Cache prices, the rarity isn't too high, but they aren't as common as the other jewels. As such, the requirements in terms of basic game items is the same, but the gold cost is increased both in formula price and crafting cost. Additionally, the formula requires level 2 in order to craft it.
Suggestions for the third group
This is going to come in two parts/suggestions due to the obvious difference in rarity. I'm just lumping them in the same group because they are both far out of the league of the other jewels.
The following formulas would be sold in Bifrost:
Formula 3: Philosopher's Cache: Gold
Formula 4: Philosopher's Cache: Platinum
Formula Costs:
Formula 3: Philosopher's Cache: Gold - 40,000 gold
Formula 4: Philosopher's Cache: Platinum - 50,000 gold
Formula Requirements:
Formula 3: Philosopher's Cache: Gold
Like with the last two, this increments up. The gold cost to even purchase the formula is higher, as is the crafting cost. Additionally, all of the game item requirements are 120% of what the base Philosopher's Cache requirements are. It also requires that you be at level 3 to craft. Not only does this mean one has to level up a little to get to this point, but it also creates a grindable formula to get past a level that is currently way, way skewed compared to subsequent ones in terms difficulty to level through.
Formula 4: Philosopher's Cache: Platinum
Finally, the Platinum Cache formula. With a formula cost of 50k and a crafting cost of 30k, one would spend a minimum of 80k gold to craft this, compared to the 7.5k for a base Philosopher's Cache. It is also deemed level 4, so one would have to break past the level 3 barrier (still a feat even with my proposed Gold cache formula) to even try. Additionally, all game item requirements are either 150% or 200% of the requirements of the base Philosopher's Cache. It's doable via effort, but it requires a fair bit more (as well as a lot more gold) to do. While gold is involved, it's not the singular reason for success as the entire system is currently. This makes it a possible feat, but not something you can do in the blink of an eye.
