Abstract: Legacy-Remaster-Hybrid Wording "ability attribute" in Spell Jealous Hex
[...]
You draw forth a hag's innate jealousy to deny a target its greatest attribute. The target is cursed with an adverse condition depending on its highest attribute modifier: Strength (enfeebled); Dexterity (clumsy); Constitution (drained); or Intelligence, Wisdom, or Charisma (stupefied). On a tie, the creature decides which of the conditions associated with the tied ability attribute to take.
