Armor Golem

Stalwart. Creatures that are behind the Armor Golem or in it's space have full cover from attacks (this does not block line of sight).

Fist. Melee Weapon Attack: +2 to hit, reach 10 ft., 1 target. Hit: # (1d6 + 2) bludgeoning damage. 

Fearsome Presence. You can use your action to frighten someone with your menacing presence. When you do so, choose up to 5 creatures that you can see within 30 feet of you. If the creature can see, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Wisdom modifier) or be frightened of you until the end of your next turn. On subsequent turns, you can use your action to extend the duration of this effect on the frightened creature until the end of your next turn. This effect ends if the creature ends its turn out of line of sight or more than 60 feet away from you.

Interdiction. When a creature within 30ft. or you is about to be hurt by an attack, as a Reaction you may move into their space or a space next to them. If the creature is the same size as you, they are pushed into a space adjacent to it (your choice). If there is not enough room for them to be pushed, you can not move into their space. Regardless, you are hit by the triggering attack using your own AC.
