Is a 6iv level 100 Pokemon which has been set to level 50 stronger or a 6iv level 50 who's level does not change? At level 100 they get 31 stat points so do they still reserve their 31 stat points when level 50 or is it the same as a level 50 Pokemon IVs ? So should I train them to level 100?
Same as a Level 50 Pokemon IVs. Stats get reverted to what it would be if the Pokemon was Level 50.
