This salamander is pretending to be a magic bracelet, in order to receive shelter and food. Since it's not actually magic, antimagic field and similar effects do not suppress this items effects.  When a creature attunes to the item, they take 2d8 poison damage. While attuned, you are resistant to poison damage. As an action, while attuned to the bracelet, you can wake up the bracelet so it starts being a salamander.  You lose the benefits of the magic item, and a poisonous salamander under your control appears within 5ft of you. It acts right after your turn and starts with 1d8 temporary hit points. If the salamander dies, this magic item is destroyed. As another action, while the bracelet is a salamander, you can turn it back into a bracelet, which appears in your hand.
