Mithril Halfplate

While wearing this armor your AC is 15 + Dex modifier (max 2).
Mithral is a light, flexible metal. A mithral chain
shirt or breastplate can be worn under normal
clothes.
If the armor normally imposes disadvantage on
Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor
doesn't.
