What are Affinity and Affection?
More The Seven Deadly Sins: Grand Cross
Each character has an affinity gauge (different versions of the same character are counted separately). You can increase affinity by giving the hero his/her favorite dish, ale, or Affinity Increase Elixir. You can increase the affinity level to LV5, with each level requiring more affinity points to level up. For each level, you’ve reached, you’ll also obtain the corresponding rewards as listed below:
Level 1: Hero Illustration
Level 2: Hero CV (Character Voice)
Level 3: Diamond x1
Level 4: Hero Motion
Level 5: Cosmetic Outfit.
Increase affection in heroes by doing the following:
1. Fighting battles with them on the team
2. Conversing with them and choosing the correct dialogue option
3. Exchanging gifts or affinity
When you increase the affection to the maximum, you’ll get a heart and rewards based on the number of hearts you collect. The maximum number of hearts increases with the number of heroes you have and the maximum level of affinity among individual heroes.
