+1 Trait Point per X The character suffers a -10 * X penalty to Endurance tests made to resist contracting diseases when exposed. If the character has the Disease Resistance trait, first subtract this value from the percentage on that trait. Any overflow is applied to the penalty. For example, if a character has Disease Resistance (25%) and they take this trait at a 3 X value, then they suffer a -5 penalty to their Endurance tests for resisting diseases.
