i dont think that the extra 5 sta will make any difference in the long run. that will be 100 hp or so. and u will be 1hko regardless. might as well put that into int as well.
Its ok, as long as you get your heap up maxed so you can get a lot of HP, i put 35 into sta, because so i can at least live from a monster hit (well if its maxed...with prevention on)
