WHAT YOU WILL NEED

• A way to tell what Seed you are on:
• Roamers on the map
• Juggler Irwin or Professor Elm ^{[Elm info]} in your Pokegear
• (Two) Chatots with the move Chatter ^[note]
• Pokeballs to catch pokemon, and rare candies to level them up (very optional)

Note that not all of these are completely required! as long as you have at least one of them it's technically possible to determine your seed, I listed them in difficulty order, and I'll explain in depth how each are used below.

• A way to advance the RNG

Some of the methods above used to verify your seed can be used to advance the RNG, but not all of them.

• Call your best buddy Juggler Irwin (or Prof Elm)
• Each call advances RNG by 1
• Listen to the song of your Chatot screaming at you. (Quickest)
• Viewing the pokemon's summary to hear the Chatter cry advances RNG by 1
• Listen to the Radio
• (advances the RNG by a weird amount, don't worry about this rn i'm only listing it for completionists sake, and as a warning to not accidentally listen to the radio)
• NOTE: Other unwanted factors may advance the RNG as well, such as NPC movements (even if they're not on the screen), so try to open the menu ASAP when you load into the game. Taking steps also can advance the RNG, so it's best to always save exactly where you need to be to interact with a static encounter/use sweet scent/etc.

How to determine what Seed you hit:

EASY MODE:

The standard ways to verify your seed, that will work for most people in most cases

• Look at where the Roamers are on the map (Entei, Raikou, Lati@s) - Quickest Method, may need extra verification
• This is the quickest verification method, but obviously can't be used if you no longer have the roamers on the map. Pokefinder shows you where the roamers are located when you load into the seed, so you can easily check if you landed on the right one. (Roamers also advance the RNG by 1 or 2 upon the game loading, Pokefinder accounts for this in it's calculations so don't worry about it.)
• There's a possibility that Pokefinder will show multiple nearby seeds that have the same roamer locations as the one you're aiming for. In that case, see the other options below to do extra verification while you're making your way to the advance you want anyway.
• NOTE: Roamers will roll the RNG a few advances forward when you load into the game, and you will need to take note of the roamer's placement BEFORE you save and close the game and start the clock changing process. This is because if the roamers are placed in a spot they previously were at, the RNG will roll an extra time to put them somewhere else. Pokefinder has a spot to put this, and accounts for the extra rolls.
• Call your best buddy Juggler Irwin (or Prof Elm i guess) - Most reliable method, and easy to do
• Each time you make a call, you'll get 1 of 3 different dialogues. These are predetermined with the RNG, Pokefinder has a way to easily find what seed you landed on via this. (Each call also advances the RNG by 1)
• (UNFORTUNATELY, there are some places where you cannot call people, such as, right before you're going to fight the champion. Meaning you cannot use this method for the Roamers :( sorry to Juggler Irwin fans that are interested in RNGing those.)

HARD MODE:

Using these methods to determine the seed sucks ass, but if you're trying to do RNG as early in the game as possible, before you reach Juggler Irwin, OR if you're some place you can't make calls and also don't have any roamers on the map, it's pretty much your only choice. Sorry!

• Listen very closely to the song of your Chatot screaming at you. - (Almost) most annoying method, and can be unreliable
• When Chatot have learned a new cry with Chatter, via you yelling a cuss word into the DS microphone, the cry actually has a different pitch each time you listen to it! This is determined by RNG, so if you listen carefully to the pitch you can use it to see if you hit the right seed.
• It's possible though. You just have to examine every seed individually because Pokefinder doesn't supply you with an easy list of what the pitches are :) I will detail this hell process later (or you can just hope you're hitting nearby the seed you want to land on, if you're confident enough, that's what i do)
• Good news! pokemonrng.com now has a tool to help you check the Chatot cries! It still only checks for the seed that you're aiming for and not the nearby ones, but it helps determine and keep track of the range the pitch falls into while you're listening to them.
• Catching Pokemon and checking their stats - Most tedious method, and also annoying
• If you don't land on the pokemon you wanted, you check it's stats and use those to see what seed you landed on. This is pretty much the last method you would ever want to use, as it's annoyingly stupid and Pokefinder doesn't have an easy way to do this. THANKFULLY the web tools out there for RNGing the starters include this check, and you likely would never have to use it otherwise due to the availablilty of the other verification methods. (unless you're trying to do a semi-prof oak type challenge to get every shiny asap before moving on :) )

How to Advance the RNG (Eggs)

• Just aim for an Advance of 0 for this, there is no reason to do otherwise 99% of the time
• Rejecting an Egg from the daycare will skip the advance it spawned on.
• Call Youngster Joey, he will advance the egg RNG by 2, for some reason.
• If Youngster Joey calls YOU while you're trying to get an egg to spawn, it will mess up the RNG, by the way :) *definitely not speaking from experience* (This is rare and not likely to happen)
