Clockwork spiders are delicate arachnoid constructs built for espionage, designed to gather delicate information from people and places important enough to be warded against conventional stealth and scrying. Spiders can record and perfectly recreate whatever sounds they hear for a short time, making them ideal for capturing the secrets of powerful enemies.

Originally a drow device inspired by the craft of their svirfneblin slaves, spiders were used to great effect in the dark political games of their underground cities before spreading to the black markets of the surface. Spiders are impossible to replicate by any but the most brilliant artificers, making them a near-priceless boon to any guild spy or scheming noble.
