What Mithral Armor does
- This armor starts at AC 15 and caps a positive Dexterity modifier at +2. A negative modifier still reduces AC.
- It does not impose Stealth Disadvantage from the armor itself, which preserves more options for sneaking.
Mithral is a light, flexible metal. Armor made of this substance 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. This is the Half Plate Armor variant.
