Iron bands of Bilarro were magic shackles that were capable of restraining creatures up to the size of giants.[1]


When not in use, the iron bands of Bilarro took the shape of a small rusty iron sphere 3 in (7.6 cm) in diameter. When deployed, they opened into a series of metal straps that tangled around their intended target.[1]


The user activated the iron bands of Bilarro by speaking a command word and throwing the sphere at the desired target. On a successful hit, the bands were deployed and entrapped the target. Once in place, a sufficiently strong individual could in principle break free and destroy the iron bands through sheer strength, but only with great difficulty.[1]

The bands could be deployed once per day and recovered their power at dawn.[1]


In 1492 DR,[note 1] a set of iron bands of Bilarro was used to hold Ott Steeltoes, an operative of the Xanathar's Thieves' Guild, by members of Bregan D'aerthe.[2]



  1. Canon material does not provide a year for the events described in Waterdeep: Dragon Heist, but Christopher Perkins answered a question via Twitter and stated the year was 1492 DR. Unless a canon source contradicts this assertion, this wiki will use 1492 DR for events related to this sourcebook and Waterdeep: Dungeon of the Mad Mage (which is referenced on pages 5 and 98 of Dragon Heist).
