Every time a character levels up, their HP will be increased by 1 by default, regardless of aptitude. To get the achievement, HP should be +2 to be counted as "all stats increase".

Your character level-up screen should look like the one below before the achievement unlocks.

When you start a new game, adjust the following settings:

1. Click on "Campaign Customization"
   
2. Under "Sliders" (the box on your right)
   
   • keep "Linear Levels" as "Off" (If you change it to "On", level stats will be fixed, and you won't be able to get the achievement in Chapter 2)
     
   • [Optional]change "Base Stat Modifier" from 100 to 200 (this is to make combat easier. We don't care about gameplay at this point, right?)
     
   • [Optional]change "XP Modifier" from 100 to 200 (this is to level up faster and reduce the number of times you have to restart the level, if you are unlucky, like me. We will get 3 chances in Chapter 2 this way)
     
   
   
3. Under "Options" (the box on your left)- "Aptitudes", click on "Unit Menu"
   
4. Under "Player Aptitudes", select "% Change", and change everything from 100 to 200

Now, you can select whatever difficulty you want to grind for the "Blessed by Aren Jee Zuss" achievement.

Elias will join our team of heroes in Chapter 2, and all his aptitudes are above 60, which increases our chance of getting all stat up.

When the chapter gameplay actually starts, move all the other heroes away as far as possible, keeping Elias alone in the middle. The enemy will only attack Elias if they cannot reach other heroes. Thus, Elias would get more exp getting hit.


Elias should be able to level up 3 times until he gets 2 exp per kill. Thus 3 chances of attempting the achievement per run. If you did not get all stats up before turn 7, restart the level by reloading the chapter save.

Rinse and repeat until you get all stats up.
