Strength

From Asda Story Wiki

Increases characters' physical attack. This is an important damage attribute for both warriors and archers. Strength is mainly relied upon by Berserkers(spear), Last Survivors (2-handed swords) and all archers, where as the Penetrating shield depends on threat ratio (the amount of damage and need to attack you a monster reads on your character) to cause the target to attack them and keep them on while in a party.
