Can Suzi devour the individual event cards attached to Crystallizer of Dreams, or would she have to devour the entire Crystallizer asset?
If the former, that seems pretty enormously powerful; it means you have a steady stream of event cards to devour and aren't likely to have to resort to eating your assets (or your teammates). Even better, you could use it to juggle multiple copies of Regurgitation back into your hand, healing damage and horror with every cycle.
If the latter, what happens to the attachments; are they devoured as well? Or simply discarded?
Unrelated: unless I'm mistaken, Suzi can benefit greatly from cards that cause her investigator card to be treated as blank (e.g. the Stubborn Detective weakness). If she builds up a healthy statline from Ravenous (Controlled Hunger), blanking her investigator card prevents her from being forced to devour one of the cards she draws during upkeep and switch back into Uncontrolled Hunger mode, but she still keeps the stat boots from Ravenous.
