In play
Robust: prowess rises by 4, health rises by 0.5, and attraction opinion rises by 10. Robust is the middle good physique trait. The character fights better and sickens less easily. Weak, Spindly, Hale, and Herculean sit on the other side of this trait.
How to get Robust
- Gain: Congenital and decided at birth: a child inherits Robust outright at a base 80% if both parents have it, 50% if one has it and the other carries it hidden, 25% if only one parent has it, and 2% to 10% if the parents only carry it. About 0.25% of children who inherit nothing from the physique line are born Robust at random, and a child who inherits Hale from both parents gets a base 50% roll to be strengthened to Robust.
- Remove or lose: Permanent for practical purposes: no treatment or decision removes it, and the character can still pass the trait on to children.
When the outright roll fails, the child can still inherit Robust hidden (inactive) and pass it to later generations, so carriers matter when choosing spouses.
Robust is also the stepping stone to Herculean: two Robust parents give each child a base 80% chance to show Robust, and when the child inherits it from both sides a further 50% roll can lift it to Herculean.
Blood legacies improve the odds: Noble Veins raises the chance of good random and hidden inheritance, and Convergent Blood adds 30% to the chance of strengthening a trait to the next tier. Faiths with the Divine Marriage tenet add smaller bonuses to the same rolls, for bad genetic traits as well as good ones.
