# Pipes of the Sewers > [!info] Item Details > | | | > |---|---| > | **Category** | Wondrous Items | > | **Rarity** | Uncommon | > | **Attunement** | Yes | > | **Source** | DMG p.185 | --- ## Description You must be proficient with wind instruments to use these pipes. While attuned to them, ordinary rats and giant rats are indifferent toward you and won't attack you unless you threaten them. The pipes have 3 charges and regain 1d3+1 expended charges daily at dawn. If you play the pipes as an action, you can use a bonus action to expend 1 to 3 charges, calling forth one swarm of rats per charge from surrounding rat populations. You can call a swarm only if you can see it or a point where it can emerge. The swarm moves toward the music by the most direct route but acts under its own initiative. If the swarm moves out of earshot, it loses interest immediately. --- ## Properties - Ordinary and giant rats are **indifferent** to you while attuned. - 3 charges, regains **1d3+1** daily at dawn. - Action to play; bonus action (1–3 charges): call **one swarm of rats per charge** from nearby populations. - Requires **wind instrument proficiency** to use. - Requires attunement.
