Gift of the Machine God. As a creature of technology a mannequin robot gains many damage and condition resistances and immunities but they are also susceptible to lighting attacks.
Crippling Strike (1/turn). If the WARDEN has advantage on an attack roll against a creature he does an additional 40 (13d6) damage on its next Warden Strike attack.
False Flesh. A mannequin robot gains a +10 bonus on Disguise checks to appear human.
Multiattack. The WARDEN robot can make two unarmed strikes.
Warden Strike. Melee Natural Weapon Attack: +9 to hit, reach 5 ft.; one target.
Hit: 20 (2d12 + 7) bludgeoning damage. This attack critical range is 18 to 20, on a critical hit, the target must make a DC 18 Constitution saving throw or become stunned for 1 minute.
Feint. If an attacker misses the WARDEN robot it gains advantage on its next attack against the same target.
During Combat Both WARDENs’ safety protocols failed long ago, and as such they don’t hold back their punches. As they fight, they offer advice to their foes, giving the PCs sound tactical advice on such things as flanking or when to fight defensively. The WARDENS both use martial flexibility to gain Improved Critical (unarmed strike), Critical Focus, and Staggering Critical during the fight. The WARDEN will ignore stunned opponents but disarm them if given the chance.
Morale The WARDENs fight until destroyed, but don’t pursue foes beyond this room.
This impassive humanoid has shiny, pale skin and an eerily expressionless face. Crafted to look human like, they are not quite there.
One of the WARDENS is a boxing robot. The characters can trick them into fighting each other; if they do they destroy one another.
