How does CHOAM's duplicate-discard ability work?
CHOAM gains 3 spice for each surplus duplicate it discards, keeping one copy. Duplicates must share a name, so Shield, Snooper, Truthtrance, Karama and Cheap Heroes can qualify, but differently named weapons don't. The CHOAM Karama dumps any or all Treachery cards, not only worthless ones, for 3 spice each, once.
