This coat of chain mail is completely black, not silver, and gives off a slight aura of black vapor.  While wearing it, you have advantage on all stealth checks (and any disadvantage applied from heavy armor is discounted), you gain a +3 bonus to AC, and any creatures within 5 feet of you that you choose take 5 poison damage at the start of each of your turns.

This armor has 5 charges, and regains 1d4 + 1 charges daily at dusk.  You can cast the following spells by expending the required amount of charges as an action: pass without trace (1 charge), invisibility (2 charges), greater invisibility (4 charges), and hold monster (4 charges).

Made of interlocking metal rings, chain mail includes a layer of quilted fabric worn underneath the mail to prevent chafing and to cushion the impact of blows. The suit includes gauntlets.
