Special Traits

  • Cadaverous Appearance. While the zombie dragon is lying still, it is indistinguishable from a mundane decomposing corpse. It can still be detected by a detect evil and good spell, or similar magic.
  • Undead Fortitude. If damage reduces the zombie dragon 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 dragon drops to 1 hit point instead.


  • Multiattack. The zombie dragon makes two attacks: one with its bite, and one with its claws.
  • Bite. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage. Additionally, living creatures must succeed on a DC 18 Constitution saving throw, or take 18 (4d8) necrotic damage and contract the zombie necrosis disease (p.192).
  • Claws. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.
  • Tail. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) slashing damage.
  • Rot Breath (Recharge 5-6). The zombie dragon exhales a squall of necrotic rot in a 30-foot cone. Creatures in the area must succeed on a DC 21 Constitution saving throw, taking 49 (11d8) necrotic damage on a failed save, or half as much damage on a successful one. A creature that fails its saving throw has its hit point maximum reduced by an amount equal to the necrotic damage taken. This reduction lasts until the creature finishes a short or long rest. If the creature’s hit point maximum is reduced to 0, the creature dies.

Legendary Actions

The zombie dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time, and only at the end of another creature’s turn. The zombie dragon regains spent legendary actions at the start of its turn.

  • Tail. The zombie dragon makes one tail attack.
  • Winged Lunge. The zombie dragon flies up to 10 feet.
  • Bite (Costs 2 Actions). The zombie dragon makes one bite attack. It takes uncommonly powerful magic (or a particularly virulent strain of the disease) to resurrect a dragon, so such creatures typically exist under the thrall of a megalomaniacal necromancer who will have gone to great pains to raise one. The rare zombie dragons to arise on their own are heralds of disease, rot and woe.
