I'm working on a Tiefling Sorcerer with the claws option from the ARG and the Draconic Bloodline which gives claws as a bloodline power. What is the effect of manifesting claws if the character already possess them?
I've had a few thoughts, the one that seems to make the most sense is that it changes the die type to the next larger (D4 -> D6) during the duration of the manifestation.
