Skeleton Vanguards are skeletons that appear in various levels in Minecraft Dungeons. They spawn with a glaive, and a unique helmet and shield. They are mainly seen serving the Nameless One, who summons waves of Skeleton Vanguards in his boss fight.

Drops
Skeleton Vanguards, like the rest of the Minecraft Dungeons mobs, drop a set amount of emeralds when killed.

Behavior
Skeleton Vanguards immediately chase players once seen. When close enough, they either stab or slash the player with their glaive
