Special Traits

  • Draining Smite. When the annihilator hits a creature with a melee weapon attack, the annihilator can expend a spell slot to also hit the target with its Life Drain. If the annihilator expends a spell slot of 2nd level or higher, its Life Drain deals 4 (1d8) extra damage for each level above 1st.
  • Spellcasting. The annihilator is an 8th level spellcaster. Its spellcasting ability is Charisma (spell save DC 16, +8 to hit with spell attacks). The annihilator has the following paladin spells prepared:
  • Sunlight Sensitivity. While in sunlight, the annihilator has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
  • Turn Resistance. The annihilator has advantage on saving throws against any effect that turns undead.


  • Multiattack. The annihilator makes two longsword attacks. It can use its Life Drain in place of one melee attack.
  • Life Drain. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 14 (3d6 + 4) necrotic damage. The target must succeed on a DC 16 Constitution saving throw, or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. A humanoid slain by this attack rises 24 hours later as a zombie under the annihilator’s control, unless the humanoid is restored to life or its body is destroyed. There is no limit to the number of zombies the annihilator can control.
  • Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage, or 8 (1d10 + 3) slashing damage, if used in two hands.

Legendary Actions

The annihilator 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 annihilator regains spent legendary actions at the start of its turn.

  • Attack. The annihilator makes one longsword attack. It can’t use its Draining Smite with this attack.
  • Command Zombie. One zombie, under the control of the annihilator, makes a melee attack against a creature of the annihilator’s choice.
  • Shield Up. The annihilator equips its shield if it is carrying, but not already wielding, it and gains an additional +2 bonus to its armor class until the start of its next turn.
  • Cleansing Touch (Costs 2 Actions). The annihilator ends one spell on itself or a willing creature it touches.
