- Q: Can you discard Clasp of Black Onyx to Corrosion or Realm of Madness if you can't reach the discard threshold with other cards in hand? A: No, in this case, Corrosion would not discard the Clasp, because weaknesses cannot be discarded from your hand except when it is at random. Even if there are no other options for Corrosion to discard, the Clasp would remain in your hand.

Pretty sure you can stick this in a Backpack & forget about it!
Sadly, Backpack specifies non-weakness items.
Haven't gotten far in Carcosa yet, but seems pretty mild overall. Basically just -1 action if you have nothing else to help.
