@Jangel13 Hmm, duly noted. So the main character of Re: Monster has an ability where they can gain the advantageous abilities of other things by eating them, and by virtue of that is able to eat virtually anything (even stuff like metals) safely.
So i was thinking that, since that character's ability allows them to assimilate the abilities of other thing they eat, that i could make something to a similar effect for an OC.
Something like "was the recipient of a great deal of organ transplants in life" would translate to this ability: "Through physical contact with the body or parts of other creatures, whether those creatures be alive or dead, they can absorb/assimilate the DNA of said other creatures. What this does is grants them a very randomly chosen trait or boon as a result."
For example, assimilating the DNA of a horned rabbit might give them horns along with a stronger skull for headbutting at the very best, or might enhance their leg muscles a bit instead, or instead confer some other sort of advantage or the horned rabbits have that the user does not already have.
However, the gist is that this "boon" or "advantage" granted is not chosen by the user, but instead by you the GM for added randomness and variety.
(Dear heavens i hope this isn't a shoddy idea...)
(Though perhaps i am being too ambitious as well...)
