The ancient black dragon zombie has advantage on saving throws against any effect that turns undead. \n'b'  Undead Fortitude . If damage reduces the dragon zombie 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 dragon zombie drops to 1 hit point instead. \n'b'\n'b' Actions \n'b'\n'b'  Multiattack .

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\xe2\x80\x99s saving throw is successful or the effect ends for it, the creature is immune to the dragon zombie\xe2\x80\x99s Frightful Presence for the next 24 hours. \n'b'  Acid Breath (Recharge 5-6) .
