Scroll
Scrolls are readable COMMON objects represented by a bright-yellow ? in Omega 0.90.4. This review index covers scroll IDs 0 through 19; four later definitions are outside this batch.
Ordinary object generation first selects an item class, then scroll generation chooses uniformly from all 24 scroll definitions. Unidentified appearances are shuffled among thirty inscriptions at game initialization. A successful read normally consumes one object, while blindness and fear prevent reading.
