For the same monster as seen in Diablo III, see Skeletal Shieldman.

A Skeletal Shieldbearer
Skeletal Shieldbearers are basic skeletons who wield a sword and shield.
Lore[]
While shieldbears are capable of enduring formidable frontal assaults, their decaying shields can only resist so much, and they are slow to protect their flanks.[1]
In-game[]
Skeletal Shieldbearers appear as undead monsters in Diablo Immortal. They are found in Ashwold Cemetery.
