Symbol spawners are NOT guaranteed to produce the same species every time, the species is instead derived from the encounterslot value (0-99), the Pokémon that occupy encounterslots will vary depending on weather and location.

Brilliant Aura Mechanics

Symbol encounters can potentially spawn Pokémon with Brilliant Aura, which boosts the amount of guaranteed max IVs the Pokémon will have. Players searching for high IV targets may opt for manipulating Symbol encounters for this purpose.

Brilliant Aura Pokémon can also have increased shiny odds, which is based on the Pokedex KO count. This value can be seen by viewing the Pokedex entry of any Pokémon. Bulbapedia contains useful information about the increased rates.

For maximum optimization with this encounter type, it is recommended to have access to the Shiny Charm and have 500 KOs on the Pokémon you are hunting, this is a time consuming process however.

Pokemon Behaviour Mechanics

Pokémon have different behaviour classes, some will be aggressive and target the player, others will be relaxed, and in some cases the Pokémon will be timid and flee when they notice the player, causing them to despawn entirely. Pokémon with flee behaviour need to be encountered quickly before they escape.

Butterfree, Vulpix, Chansey, Horsea, Dunsparce, Blissey, Ralts, Whismur, Drilbur, Audino, Trubbish, Zorua, Ferroseed, Inkay, Phantump, Noibat, Wimpod, Skwovet & Silicobra.

If the Pokémon you intend to hunt appears in this list, take note and proceed with caution when attempting to hit your target frame.

Dex Recommendations & Ability Boosts

Dex recommendations can be found by opening the Pokedex, when a Pokémon is recommended the encounterslot value for that specific Pokémon is boosted. Storm Drain, Lightning Rod & Harvest abilities will also boost the encounterslot value of Pokémon of the corrisponding type (e.g Harvest boosts grass types).

Neither of these boosting methods are supported in the RNG tool at this point in time, avoid using them as this will produce inaccurate results.

1. Open SWSH_OWRNG_Generator_GUI, then type your 5 digit TID/SID into the correct fields of the main window (for shiny Pokémon only).
2. Open the Encounter Lookup sub window, then type the species name of the Pokémon you plan to RNG abuse, select an appealing symbol encounter.
3. Confirm that the filters have been set properly inside the Main Window, encounter filters can be found on the left-hand side.
4. Set the correct KO count inside the assigned field on the left, this should match the value displayed by the Pokedex for the Pokémon being hunted.
5. Set your search filters inside the middle portion of the Main Window. You can filter for specific Marks, IVs, Shininess, etc.

Example - Encounter Lookup specifies Slippery Slope in overcast weather for Phantump, this information has been automatically filled inside the main window. The KO count for Phantump according to the Pokedex is 500, and the search filters were also manually configured to search for a Shiny with any mark.

For Symbol encounters, stand where there is a clear, straight line between you and the area that contains your target Pokémon (patch of grass, cave, etc.). Avoid areas that trigger other Wild/Static spawns. The positioning in Figure 2 is ideal, minimal NPCs, no extra spawned Pokemon, and a clear line between the player and the target spawner.

Slippery Slope is notably "quiet" in calm weather. Advancement speed is based on location, NPC count, and weather. The more quiet the area, the slower the natural advancements are, and the easier it will be to hit your target frame. Avoid rain or thunderstorm weather as this will create instability due to erratic advancements.

If you can't find a good spot, knock out any static spawns blocking your path. They will remain despawned until you return to the area after a date change.

After identifying seeds using the Retail Seed Finder, a Shiny Phantump can be found on advance 2016-2020. Target frames can often appear in clusters, which are multiple frames in a row (or close to each other) that produce the same end result.

Due to having multiple frames that can potentially produce your desired Pokemon, searching for clusters is ideal. You may wish to keep searching for target frames until a cluster appears.

Undesirable result?

1. Save in the correct position, then close and re-open the game to refresh the seed.
2. Identify the seed again using the Retail Seed Finder feature.
3. Search for a new target frame, repeat this process until a desirable result has been found.

Keep the game paused after finding a desirable target frame to avoid any unwanted advancements, as this may cause you to overshoot your target frame depending on location.

If you have been following along you should now be stood in the correct position in-game, have calibrated your NPC count, and know your current seed.

Step-by-step:

1. Re-identify the current seed if you have lost track. Click the Update States button on the main window after doing so.
2. Open the Menu Close Advances Viewer sub window, type the number of NPCs into the NPCs field, then search. Take note of the amount of frames that will be consumed from closing the pause menu (inside the Jump column).
3. Unpause the game, then run into the area that contains your desired target and encounter the first spawned Pokémon, capture it, then use an IV calculator to determine the IVs.
4. If the Pokémon encountered does not match your target species, use the Encounter Lookup to fill in the details of the Pokémon you encountered. Remove any active search filters and enter the correct KO Count after doing this.
5. Find the advance that generated the Pokémon in the search results, then subtract the amount of frames that were consumed from the pause menu. This will be the delay for this encounter.

Example - If the Pokémon was generated on frame 10, and 7 frames were consumed from closing the pause menu, this means the delay for this encounter is 3.

Step-by-step tutorial:

• Advance towards your target frame using any method listed inside the advancement table on the main page. Consider date-skipping for long distance-advancements.
• Return to the correct position in-game once you are within a few thousand advances of the target frame. This will ensure that you do not overshoot when doing quick advancements.

If the weather condition does not match the conditions to spawn your Pokemon, change the date on your console BACKWARDS until the correct weather is displayed on the map. Changing the date backwards will avoid unwanted advancements.

• Pause the game and re-identify your current seed, then click the Update States button to reflect the new RNG state inside the main window and search for your target again.

• Subtract the delay from the actual target frame (e.g 1000 (target) - 3 (delay) = 997) this will set the new target frame and this will be the frame to spawn the Pokémon on.
• Open the Menu Close Advances Viewer tab, and enter the number of NPCs calculated earlier into the NPCs field, then click Search.

If you can see your target frame(s) within the Menu Close Advances Viewer search results, great! This means menu close prediction can be used to hit your target frame with no extra issues and the next two steps can be skipped.

• If you do not see your target frame in the search results, increment the number inside the Init Adv. field by 1, repeat until the target frame is visible.
• Perform some animation advancements according to the number inside the Init Adv. field. For example, do 5 advancements if the number inside the field is 5.

In extreme cases you will not be able to reach your target frame using menu close prediction. To counter this, aim to get as close as possible to your target using menu close prediction, then use player movement advances to hit your target frame.

• Open and close the pause menu until a single menu close lands you onto the target frame (do any required movement advancements here if you do not land directly onto the target frame).
• Unpause the game, then move towards the spawn point of the Pokémon as quickly as possible, then initiate the encounter to confirm the result matches what is expected.
