Gnomish Knock-Knock

The Gnomish Knock-Knock begins as a specialized optical instrument in Book 4, a heavy telescope engineered for naval and siege applications that combines mechanical precision with magical enhancement. Its low-light zoom and description popups make it invaluable for reconnaissance and targeting, though its instability hints at the dangers of gnomish engineering. Across the series, the device evolves from a passive observation tool into an active combat asset, its targeting capabilities proving crucial in large-scale battles and dungeon navigation.
