Lazzero wields an Asmodean buckler.

A buckler is a small shield weighing approximately 5 lbs. that is strapped to the forearm. Its small size and lack of need to hold it, allows the wearer to use most ranged weapons without being unduly encumbered. Nearly the same is true for those using a two-handed melee weapon or holding a smaller weapon with a double grip. Spellcasters may also cast spells with somatic components with their buckler-wielding hand with only minor inconvenience.[1]
