Trigger You fail a Will save.
The experience of coming back after death has granted you a strong sense of resolve; devilish words, slick spells, and conniving trickery can’t easily catch you unprepared. Reroll the triggering save, using the second result only if it’s better.
Traits
Rare: This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
Fortune: A 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.
Reincarnated: These rare ancestry feats are available to any character who has reincarnated at least once either as part of their backstory or because of a reincarnation that took place during play.
Universal Ancestry: A feat with this trait is available to all ancestries.
