Many of these questions have probably already been answered by many people much smarter and much more skilled at pokemon than I. However, I feel the need to aks them out of a fear of my own ignorance.
1) Where can one find leftovers in D/P without action replay etc?
In the victory road after you defeat the E4, another part of the cave is opened up
2) How do you find out your friend code? I would like to post it but I do not know how to find it. Noobish, yes.
Any pokmn centre, below. Need wifi connection though
3)Why are duskull so hard to find in D/P? I searched for hours on route 224 at night and did not find one.
You need a pokeradar to find one.
4)How important are EVs to stats? I look at some people`s stats and they are monstrously higher than my own similar level pokemon of the same type, is that jsut bad luck?
EVs can provide up to 63 points of boost to any stat, if your pokemon are ev trained and still have lower stats than other same lvl pokemon with the same ev training, it's probably due to your pokemon's lower ivs
Thank you once again to anyone who deigns to answer these ridiculous questions.
