Strength
Strength measures bodily power, leverage, and the ability to force the world to move when it does not want to. It matters most when a character’s plan depends on heavy weapons, grappling, shoving, climbing through resistance, or wearing armor that assumes physical power instead of agility.
Melee pressure. Strength commonly supports attack and damage with heavy or close-quarters fighting styles that are built around force instead of finesse.
Athletic actions. Climbing, jumping, swimming, grappling, and shoving often read like technique checks on the page, but in play they are usually Strength moments first.
Load and armor plans. Characters who expect to haul gear, use heavier kits, or stand in the middle of the fight often want Strength high enough that the rest of the build is not fighting its own equipment.
Raise it when the class expects force
Martial builds that want to control the front line or lean on Athletics should treat Strength as a core score rather than a cosmetic one.
Don’t overbuy it if the build is Dexterity-led
If the character fights with agility, range, or finesse, Strength can often stay merely functional unless the concept specifically needs the physical utility.
