EV Training is a term used in the Pokemon games which essentially refers to going into combat against certain enemies who give specific stat growths.
For example, a Pikachu gives 2 Speed EVs, where a Haunter gives 2 Sp. Attack EVs.
I was wondering if there is anything relatable to FE: Heroes,
for example does killing a Armoured unit give a better chance at getting +1 Def on level up? Or does killing an enemy Hero (as opposed to an unnamed unit) grant better bonuses upon leveling up?
Another thing I noticed is that units tend to gain more stats if they level up during a harder encounter, for example I did a level 20 Training Stratum with my team at an average level of 15 and they seemed to get more stat increases when they leveled up, however this could just be a fluke.
In short, does the type of enemy and level of enemy affect the stat growth of your characters when they level up?
