Jirachi download

From now until the July 16th, you can download Jirachi through the Nintendo Wifi Connection as a Mystery Gift. This download is available in Europe and North America.

Random nature, level 5, original trainer: SMR2010
Moves: Wish, Confusion, Rest, Draco Meteor.

Even though it has a different trainer ID than the previous Jirachi, it does block a second download. The upside is that you can get this Jirachi into your HG/SS game, which you couldn't before.

Joey's Rattata

This is only slightly a Pokemon topic - Joey's Rattata meets probability.

If you haven't played HG/SS, you might not know about his Rattata. "It's like my Rattata is in the top percentage of Rattata." He calls you often, to talk about important things...like his Rattata. Even after it's evolved to Raticate, he'll still have many many thoughts to share about his Rattata.

It got me to thinking - what IS a top percentage Rattata? How difficult would it be to just stumble across one?

First, we need to start with what a top Rattata would have for stats. As we're in the Egg Moves blog, let's assume Joey is talking about IVs - anyone can train a good Rattata with EV training.

Second, each of the 6 stats range from 0-31. My ideal Rattata would have some specific IVs in certain stats, but let's just assume for quick math, we just care about the best ones we could expect out of 100 Rattata, if they were all naturally occurring. Amongst my friends who are serious about IVs, ideally, they get all 31s. They'll settle for 28+, honestly...so we'll work from that point.

Probability is a longer topic, but it breaks down to some quick math if you have Excel handy - just use BINOMDIST function. (There's a 4/31 chance of getting a 28 or higher which would count as a success. Figure out the number of successes out of 6, and you're there.)

If we believe in getting a 28 or higher qualifies - 3 IVs gets us to top 2%. Sadly, it takes us 4 to make that top 1%. It almost takes us to the top Rattata in a thousand!

If you like 30+ IV stats, a top Rattata would only need 2 IVs of that range to make the top 2%. Sadly, that top percent is elusive...it would take 3 to break into it - making it a one in a thousand kind of Rattata.

Breeding that kind of Rattata takes dedication, checking the right parents and re-breeding as the children develop into stronger genes than their folks. With judicial use of EV training items mentioned in the previous post, it's more likely in less time. Good luck!

P.S. As an odd heads-up, I was breeding Rattata for stats, using two EV training items instead of item+everstone. I assumed that each stat would get locked in from the item, but in a couple of circumstances, only one make it in! I'm guessing the third stat donated from the parents can overwrite the "lock-in" stat. Interesting!

Breeding in HG/SS

I'll admit, I do most of my breeding in my Diamond game still. I have all 493 Pokemon in the PokeDex - if I no longer have a Pokemon, GTS is a friendly one-stop shop. It's also linked to my Pokemon Ranch...if not GTS, my Ranch generally has something (beyond the hundreds of Pokemon I've put on there).

But HeartGold and SoulSilver has a powerful motivator: IV breeding

IV (Inherent Value) stats represent the genetic traits of a Pokemon. The egg receives random IVs to start with, and then starts shuffling in up to 3 random stats from its parents. Sometimes those 3 stats overwrite each other, so it could be as few as only 1 stat from the parents. Oh, sadness.

It still means that if you have parents with good stats, you're more likely in general to have better babies. (Likewise, if the parents have bad stats...let's not go there.) But it was still random on what was passed on, until now.

The way it is now: if you give the parents the correct EV training items (Power Weight, Power Anklet, Power Lens, Power Band, Power Bracer, and Power Belt) that parent WILL pass down that stat.

I recently bred some Pokemon - I wanted a high attack stat, and good speed. The father didn't have very good stats, except for his 31 attack. I gave him the Power Bracer, gave the mother an Everstone (so she'd pass along her Nature,)...and bang. Every single egg resulted in a 31 attack, out of the 24 eggs created. (31 for an IV is the highest you can get - 0 is the lowest.) Out of those eggs, I found one with the right Nature and good Speed.

Again, this trick only works in HG/SS. It probably means I'll be doing more breeding over there, but it's hard to give up my habits - knowing where and how fast it takes to EV train is completely different in HG/SS.
