The Night's Gift

The Night's Gift +5 is heavily enchanted leather armor, which requires a strength of 3 to wear this. It has an armor class of 3, weighs 5 lbs and it also provides a +20% hide in shadow bonus. Mages and sorcerers can't wear this armor. This item appears Baldur's Gate II: Shadows of Amn. It's gained as a reward from the mayor of Umar Hills when the muders have been stopped. It's very powerful leather armor, perhaps the best piece.

In-game description
"Originally blessed by Shar, this armor has a long and interesting history. Only the greatest of thieves have ever owned this heavily enchanted armor. The essence of night has been woven into the dark set of armor so that it feels like normal armor but encloses the wearer in a mass of twisting shadows."
