Trigger You're about to attempt a saving throw against a mental effect.
You feel a strong connection with your progenitor and can convince yourself an effect targeting your mind was meant for theirs instead, allowing you to shrug off harmful effects. Roll the saving throw twice, and take the higher result. However, subsuming your identity is disturbing, and you're Frightened 1.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ConcentrateAn action with this trait requires a degree of mental concentration and discipline.
FortuneA fortune effect beneficially alters how you roll your dice. You can never have more than one fortune effect alter a single roll. If multiple fortune effects would apply, you have to pick which to use. If a fortune effect and a misfortune effect would apply to the same roll, the two cancel each other out, and you roll normally.
MentalA mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
ReflectionA creature with this trait has the reflection versatile heritage. Reflections are beings who are copies of living people, whether through cloning, planar duplication, or another mechanism. An ability with this trait can be used or selected only by reflections.
