How do you check the nature of a shadow pokemon you just caught in XD? I can find the stats, but not the nature. How am I supposed to SR for Tangrowth without it?
Like I did. Trial, and error, and trial, and error. You look for the stat that has the highest IV possible with the nature you want. Compare to what you have.
Managed a Bold 30 / 7 / 26 / 15 / 27 / 19 and Relaxed 17 / 31 / 26 / 26 / 30 / 31 that way, in two different playthroughs. Going for a third type now.
Or, monotonous plan B, buy many Colognes in Agate, rub, check, reset, repeat.
