Re: Effort Values/IVs
well, ill just do the basics and someone else can go into more detail if needed. Effort Values (EV's) are bonus points a pokemon gains during battle. Certain pokemon give off certain EV points, basically.
Each pokemon has a total of 510 EV's to use and only 255 can be used on one skill.
by level one hundred, and if you have been giving carbos and iron and such, it is likely/indefinite that you have used up your EV's.
therefore there will be no effect of vitamins
(Vitamins give 10 EV per use)
