Actions

Multiattack The henchman can attack twice with its Knightly Sword or Wrath Axe.

Reactions

Guarding If the henchman didn't move last turn, it can use its Reaction to a creature entering its reach. Upon a hit, it doesn't deal damage but reduces the target's speed to 0 ft.
Defending As a Reaction, the henchman can add 1d4 to its AC against an attack that would hit it.
