For max special attk kill 30 litwicks while holding the power lens, then removed the lens and kill 2 more thats a total of a 152 sp attk evs, after that 10 calciums will bring up the total to 252 the max amount of evs you can have in one stat
1 point sucks but at least hes a maximum encounter, you have to continuosly kill the same pokemon and run from anything else.
lol good point just give me a moment i'm trying to see if there are any good items that i could benfit but yeah I'll be in there in a min to get the Power items.
