Ah-ha. I see, said the blind man. Interesting; you can thus acquire a +2 bonus to every attribute (1.6 essence, metavariant or Changeling type, 160 BP / 320 karma) and a total of +3 to one of them.
Nasty. An elf with both Charisma and Agility at a natural maximum of 10, or augmented of 15. Worse -- a Vampire or Nosferatu. Vampire with one at 10, one at 11; Nosferatu able to bring that +3 to INT, LOG, or WIL -- all of which already get +2, sending them to 10/11.
Gaahhh!! Evil, evil villian. 'What, you thought he was actually dead??"
