To determine the correct equipment for your hero, you need to determine the heroes primary statistic.

Each hero has 5 statistics, they are as follows.

STR (Strength) – Increases the Hero’s WPN ATK during battles.

INT (Intelligence) – Increases the Hero’s TAC ATK during battles.

AGI (Agility) – Increases the Hero’s WPN DEF/TAC DEF during battles.

VIT (Vitality) – Increases the Hero’s HP during battles.

LUK (Luck) – Increases the Hero’s Initiative during battles.

To determine your Hero’s primary statistic you need to

1st open up your Hero selection screen.

Select portraits so you can see all the Hero’s in the game.

Select the Hero you would like to inspect.

From here click “Max Level” at the bottom right and “!” at the top right.

Now you can see what the Hero’s statistics would look like at max level.

The highest statistic out of STR & INT determines the main statistic for your selected Hero.

Using this statistic, we can determine the equipment that this Hero needs.

In my example you can see the highest’s statistic is STR, so this hero is better with gear that has the STR attribute.
