Champion can be built around Strength or Dexterity. Constitution supports both versions.

Strength

Strength is ideal for heavy melee weapons, Athletics, and a conventional front-line warrior.

If the Champion's specialisation rewards Strength-based attacks, Strength becomes even more important.

Dexterity

Dexterity is ideal for bows, ranged weapons, finesse weapons, initiative, Dexterity saving throws, and several mobility skills.

A dedicated ranged Champion will normally place Dexterity first.

Constitution

Constitution improves hit points on the d10 chassis.

It is also one of the Champion's saving throw proficiencies.

A weapon-focused character expects to take damage, so Constitution is a strong secondary priority.

Wisdom

Wisdom can support awareness, Insight, Hunting, and travel-related competence.

It does not normally power the base martial features.

Charisma and Intelligence

Neither is central to the base Champion chassis.

They can support leadership, lore, or character concept.

Captain uses Charisma mechanically much more heavily than Champion.

Practical priorities

Typical Strength Champion:

Strength → Constitution → Dexterity / Wisdom according to equipment and role → remaining abilities

Typical Dexterity Champion:

Dexterity → Constitution → Wisdom → remaining abilities

Sharp-shooter generally pushes a Champion toward Dexterity and ranged attacks, while Slayer usually makes Strength and melee weapon damage more attractive, so the chosen Way can change the order of secondary priorities.
