Feat: Linguistic Revival
You achieved fluency in different languages with each reincarnation, and your brain remembers much of the grammar, idioms, and obscenities that you spouted in old lives. You gain Truespeech as a 5th-rank occult innate spell that you can cast once a day on only yourself. While the spell is active, you get a +2 circumstance bonus to Diplomacy checks while speaking to a creature in a language other than Common.
