What Does Strength Affect?

Increase Carry Weight and Melee Damage

Strength will allow you to carry more weight and deal increased melee damage against enemies.

Unlock Strength Perks

Leveling up your Strength stat will unlock other perks under it in the Perk Chart. The greater the value of Strength, the higher the number of perks that you can unlock.

However, you will still need to level up your character, as most perks have it as another requirement!
