Athahetairoi

Unfailing Loyalty. Athahetairoi have advantage on checks made to resist the effects turn and destroy undead abilities.

Undead Fortitude. If damage reduces the athahetairoi to 0 hit points, it must make a Constitution saving throw with a DC of 5+the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.

Searing Vengeance. Weapon attacks made  by the athahetairoi deal an extra 2d8 additional fire damage.

Hoplon Defense. An athahetairoi recieves an additional +2 to its armor class if adjacent to another athahetairoi.

Multiattack. The athahetairoi makes two attacks with its spear.

Melee Attack. Spear: +6 to hit, reach 5 ft., one target. Hit: 17 (1d6 + 3) piercing damage plus 10 (2d8) fire damage.

Binding Attack. (Recharge 5-6) The Athahetairoi makes a spear attack. If the athahetairoi hits, opponent must make a Constitution saving thrown (DC 15) or be paralyzed for one minute.

Frightful Presence. Each creature of the athahetairoi choice that is within 120 feet of the athahetairoi and aware of it must succeed on a DC 15 Wisdom saving throw or become Frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the athahetairoi Frightful Presence for the next 24 hours.
