There is most certainly a plot to be played with the gifts of rebirth, yeah – but that’s not to say they’ll be particularly rigidly tied to the plot either. A lot of the utilization of gifts of rebirth will be in certain moments of despair and will focus more on characterization and plot purposes then just “time to use my special power!” syndrome that is often seen in scenarios like this. But I will state that the idea behind it is to give powerful albeit dynamics abilities that are untapped to the party at a given time.

That probably sounds like a mess, though.

While trying to think of something, I happened to think about the character of Raistlin Majere from the Dragonlance series and his hourglass eyes; this also brought to mind the Mystic Eyes of the Fate/ and Tsukihime series.

Would something like "eyes that see and read the emanations of magic" or "eyes that see through illusion/see the "truth" of whatever is captured in their sight" be permissible? Assuming that, like all the other powers, they only activate at certain times and aren't able to be turned off and on like a Sharingan?
