The Warder's Signet

Locations

 * In Baldur's Gate II: Throne of Bhaal, this ring can be obtained from the Deck of Many Things, which is dropped by the Cambion addicted to gambling at the end of the Maze Level of Watcher's Keep. To acquire the ring, the player must draw one of the following cards the very first time they use the Deck: the Donjon card (save at -4 or be imprisoned) or the Ruin card (party loses all gold, no save). After this, the player has a chance of drawing the Key card on his 2nd draw from the Deck, which will give him The Warder's Signet +3.
