I really want that "foreign element absorbing" to be something that 2nd gen DS can't do.

Just having DS lacrima implanted into your body, while the "real" DS have to spend years or decades of training to gain their powers seems like a cheap shortcut to get the same power, so I'd really like it if there was a downside to the method (other than the trouble of obtaining the lacrima).
