Scroll of Magic Mapping

The Scroll of Magic Mapping is a magical item that, when read, reveals the layout of the current dungeon floor and all hidden doors and secret passages. It also reveals any secret level objects (such as hidden traps on level objects) on the current floor.

When read, the Scroll of Magic Mapping reveals the entire layout of the current floor (all discoverable cells are marked as mapped), discovers any terrain flagged as SECRET (hidden doors, secret passages) and any level objects that have `secret() == true`. The locations of items and creatures remain unknown.

• Full Map Reveal: Reveals the entire current floor layout (all discoverable cells are marked as mapped via the `mapped[]` array)
• Hidden Doors: Discovers any terrain with the `TerrainFlags.SECRET` flag (e.g. hidden doors, secret passages)
• Secret Level Objects: Discovers any level object that reports `secret() == true` (e.g. secret traps on level objects)
• No Effect on Enemies: Does not affect enemy positions or behavior; enemy and item locations remain hidden
• No Trap Disarmament: Does not disarm visible traps - it only marks trap cells as mapped/visible. Traps on level objects are only discovered when those objects report `secret() == true`

• Exploration: Essential for mapping out unknown areas
• Safety: Helps avoid dangerous areas and revealed traps
• Planning: Enables planning of safe routes and escape paths
• Resource Management: Best saved for important moments when mapping is needed
