== Test Description ==
Use the swimming skill to catch Oysters in Egypt's waterways. Assemble pearls from Oysters into a necklace. Visit Schools and Universities of The Human Body so that instructors may assist in your design.

== Task ==
[[Task/Test of the Oyster Catcher]]

== Additional Information ==
This is the seventh [[Tests|test]] in the discipline of the Human [[Body]].

In the '''Test of the Oyster Catcher''', you are to make a necklace from 14 [[pearl]]s of varying sizes. Pearls can be obtained by swimming into water, finding a set of bubbles (which represent oysters), and then solving a small puzzle which will "catch" the oyster. Once you have your pearls, you must set them in the correct order to make your necklace.

== Passing the Task ==
* UBody = Sign up for the Test
* SBody = Learn [[Swimming]] (costs 10 [[Linen]]) (may be done prior to starting test)
* You enter the water by walking straight up into it.
* [[Swimming]] is done similarly to running in that left-clicking somewhere will swim you there (but right-clicking won't stop you). Terrain steepness is a factor in determining where you can and cannot move. If you're swimming in rivers or lakes, this should not be a big deal. However, this means you can't go too far out into the Red Sea or Mediterranean Sea.
* To get out of the water, click on dry land, or select the Stop Swimming option from your Special menu. Be careful: it is possible to leave the water in places where you can't get back in.
* To Dive: RIGHT CLICK on the water where you wish to dive

=== Finding an Oyster Bed ===
Oyster beds are represented by a grid of bubbles that can be of multiple colors (blue, green, white, plus off). Beds that give larger pearls are set on a larger grid and have more colors.
* An oyster bed will be visible from land.
* Small pearls come from 5x5 grids of blue, and in addition, the square you dive on does not toggle.
* Medium pearls come from 6x6 grids of blue.
* Large pearls come from 7x7 grids which appear as blue and green - they toggle through a cycle of blue, green, and off as you dive.
* Huge pearls come from 8x8 grids which appear as blue, green and white.

You must have "Fountain Detail" in your graphics options turned on to see the bubbles
(Self >> Options >> Video).
Any setting above minimum will do, though the higher the setting, the brighter the bubbles.
[[Image:Fountain_0.jpg|500px|Fountain Detail at lowest setting]]
[[Image:Fountain_5.jpg|500px|Fountain Detail at highest setting]]

[[Oyster Bed]]s occasionally appear on top of each other. Once you start diving, all but one of the beds will disappear. In some of these cases, the bed may behave oddly, with some bubbles "staying off" or "staying on" unexpectedly. It is unknown if these circumstances have any other effect. If two appear almost touching, diving in one will make the other disappear.

It appears that any given location yields pearls of different sizes, but of the same color. Most colors appear to cluster, with some colors only known to appear in particular regions.

The following pages are good help for listing beds found and colors of pearls retrieved from them.

=== Solving the Bed ===
In order to retrieve the [[pearl]] from the oyster bed, you must get rid of all the bubbles in the grid. This puzzle is similar to the game Lights Out, in that you are given a grid of bubbles that are either "on" or "off" and you must turn them all off.

Grid spots are toggled by diving.
* For small size grids, diving on a spot will toggle all the orthogonal spots around it, but not the one where you actually dove.
* For all other size grids, diving on a spot will toggle that spot and all orthogonal spots around it.
* Each spot will cycle through its possible states (off plus each possible color for that grid size) in order as it is toggled.

Once all the spots are off, you will receive a [[pearl]] and 7 deben of [[Oyster Meat]].

A bed will reset if left still for about two minutes. In addition, beds do despawn, so you won't be able to sit at a bed for hours on end trying to solve them.

== Making the Necklace ==
In order to pass the test, you need to fit these pearls retrieved together and form a necklace.

A complete necklace will require:
* 7 small pearls
* 4 medium pearls
* 2 large pearls
* 1 huge pearl

There is a numbered slot for each pearl of these sizes (small position 1, small position 2, etc.).

Each slot requires a pearl of a specific color, with the exception of the Huge (which can be any color). You do not know what colors are needed for each pearl initially. How you determine this is by fitting a pearl into the necklace, then showing it off to the instructors at a School or University of Body. They will report to you the number of correct colors and number of correct positions for each size. (This is similar to the old board game [http://en.wikipedia.org/wiki/Mastermind_%28board_game%29 Mastermind].)

If you inserted a pearl in the wrong slot, you can remove it through the test menu. There is a chance of breaking the pearl, with a higher focus giving you a better chance to keep it intact.
* At 0 focus the pearl will ALWAYS break. (This is no longer true, I successfully removed a small pearl at 0 Focus on Oct 14 2015. --Aethan. I successfully removed 2 out of 5 small pears at Focus 3, and 7 out of 8 at Focus 6, 2021-11-09 --GiantPineapple)
* At 7 focus, the pearl will break most of the time (85% on a very low sample, 6 out of 7 breaking)
* It is unknown what the formula for pearl breaking is, however focus at 75 still resulted in around 10% breakages (3 out of 32 breaking).

You may remove pearls that are placed in the right slot, but this is probably not something you want to do.

Strategically, given that colors seems roughly indexed to regions, you will save time if you begin inserting pearls as you find them (checking at an SBody or UBody with each insertion, of course). For example, if you get 0 correct colors off a single small white pearl, you can avoid small beds in areas that only produce white pearls. If you get 1 for 1, keep going after them; you don't know how many you need until you hit X for X+1.

You cannot use pearls caught by someone else in your necklace, so once you know a pearl is useless to you, you can remove it, even if it breaks without it affecting your chances at this test. Make a batch of focus food only once you have filled the necklace with right color / wrong location pearls or if you plan on keeping the pearls for the [[Throne of Pharaoh]] or to grind up in a chemistry lab for use in chemistry.

=== Admiring a Pearl ===
When you have a pearl in inventory, you can admire it under "Tests->Test of the Oyster Catcher->Admire". You will get a screen showing where the pearl was found and by whom.

When you have more than one pearl of the same color and size in your inventory, attempting to admire any of them will only look at the first one. You have to put the rest down or in a chest and look at them one at a time.

== Advancement ==
As you insert pearls into their correct positions, you will receive [[Talent Points]].

'''The mechanism for receiving points is to be confirmed'''

Add Oyster Advance Data here : [[Oyster Advance]]

== Passing the Test ==
When you have all 14 pearls correctly inserted, show the necklace to your instructors, and you will pass the test.

== Instructors ==
Please note that this does not refer to your fellow players but rather the scientists at the University of the Body.

Go to UBody or SBody and select Tests. Then select Oyster Catcher and select the option to show the necklace to the instructors. You will come up with a dialogue box showing your progress. This progress chart will tell you which pearls are the right colour and if they are in the correct setting.

== T11 Regional Pearl Colors ==

In past tellings, the colors of pearls one could find was limited by the area of Egypt in which you were diving. Under the assumption the same is true now, we should pool data on what we're finding. If someone can determine boundaries other than region boundaries that control this, this could be refined.

Please note that if you edit the following list, 'Smoke' pearl's color is listed as 'Silver'
