I know the Samsaran mystic past life ability has been done to death but i am curious to see if anyone has found interesting new uses for it. Personally i have just come up with the idea of a Nimrathi Ranger 1/Druid with the shapeshifting hunter feat and instant enemy as a 3rd level druid spell netting him by 7th level the ability to treat any enemy as a favored one at +4 with a swift action spell.
