I hate to ask this, but I saw that there was a spread of Yvetal's IV's at level 50, is there one for Xerneas as well?
Also; was there a confirmation that if you kill the legendary first and then save for the SR-refaces, the RNG still takes place?
Just run from the very first battle, it will be battleable without the cutscene before it and you can save right in front of it.
IVs and Nature are randomized each time you engage.
Check the stats in the following battle.
Note that you can't know exact IVs at lvl 50, if 4 or more stats have their maximum value for lvl 50.
30 and 31 IVs both give the same amount of hp / stats on lvl 50.
Max hindering/neutral/beneficial (displayed) stats on lvl 50:
Hp: 201
Atk: 135 / 151 / 166
Def: 103 / 115 / 126
SpA: 135 / 151 / 166
SpD: 106 / 118 / 129
Spd: 107 / 119 / 130
Now, if you have 4 or more stats at their maximum value, you can't know if one of them is 30 IV, since only 3 are guarenteed to be perfect and 30/31 IV yields the same.
You need to rare candy to the following levels to determine 30 or 31 IV: (
faint Xerneas/Yveltal in the battle after capture so it doesn't get EVs!)
Stat / LvL /___30 IV______/____31 IV
HP / 51 /______204______/____205
Atk / 51 / -137 153 +168 / -138 154 +169
Def / 53 / -108 121 +133 / -109 122 +134
SpA / 51 / -137 153 +168 / -138 154 +169
SpD / 52 / -109 122 +134 / -110 123 +135
Spd / 52 / -109 122 +134 / -110 123 +135
Minus indicates hindering, plus indicates positive nature, obviously.
Also, yay me for not knowing how to make tables in this forum >_>
