Buckler

Lazzero Dalvera wields an Asmodean buckler.

A buckler is a small, light shield typically made of steel that is strapped to the wielder's forearm.

Due to its small size and the capacity to use one without holding it in a hand, a buckler's wielder can also use most ranged weapons without becoming 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.
