This shield is large and covers the wielder almost entirely from the front, it's material is lighter than steel and as hard as dragon scale. 

When an enemy misses an attack against the wielder of this shield is granted advantage on their next attack. If an ally misses a melee attack within 30ft of the wielder, the wielder may use their reaction to add their Wisdom modifier to the missed attack. This function of the shield may only be used up to Wisdom Modifier times per day(minimum of 1).

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
