Don't feel dumb, mate. I used to be the same way. Basically, EV points (effort values) are used to gain extra points for stats. Now, before I teach you want they are, I'd also like to tell you that you should always know what your pokemon's base stats (IVs) are. Which I will go over. EVs = Effort Values Essentially what you'll be doing with these is working to battle (from a low level like level 20) certain pokemon with certain "boosts" in EV that benefit your pokemon. For example, Suppose you want to raise a super-high defense Skarmory (which rock). Just fight a ton of Geodudes/Gravelers/Onyx until you max out your EVs for that particular stat. Because Skarmory specializes in defense, you can get a LOT of defense from battling a TON of gravelers. Gravelers give you 2 Defense EV points. Which means you can still have another 254 to gain. Also, you can pile up special items like Macho Brace to amplify this to as much as 8 at a time. Now, each pokemon can only gain a total of 512 EV points. As a result, only 1 stat can hold 256 or so. However most of the time they don't count the last four because you can only get 3 on the last part. Every 4 EV points you can get, you get 1+ on that stat when you level up (depending on which stat the pokemon you just defeated boosts in terms of EV). So basically... fight a lot of a certain type of pokemon that specializes in a certain stat to gain more stat points in the stat you want. I can help you more over MSN if you want. I am like, half asleep so this probably sounds like gibberish.
Thanks guys. And.... since when does an avatar need effects?
