Special Traits

• Magic Resistance. The apocalypse knight has advantage on saving throws against spells and other magical effects.
• Marshal Undead. Unless the apocalypse knight is incapacitated, it and undead creatures of its choice within 60 feet of it have advantage on saving throws against features that turn undead.
• Spellcasting. The apocalypse knight is a 20th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 17, +9 to hit with spell attacks). It has the following spells prepared:
  • 1st level (4 slots): false life, inflict wounds
  • 2nd level (3 slots): misty step, shatter, silence
  • 3rd level (3 slots): speak with dead, vampiric touch
  • 4th level (3 slots): banishment, fire shield (chill shield only)
  • 5th level (2 slots): cone of cold

Actions

• Multiattack. The apocalypse knight makes three flail attacks.
• Flail. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 11 (1d8 + 6) bludgeoning damage, plus 18 (4d8) necrotic damage.
• Frost-bound Orb (1/day). The knight hurls a magical ball of decrepit ruin that explodes at a point it can see within 120 feet of it. Each creature in a 20-foot-radius sphere centered on that point must make a DC 18 Dexterity saving throw. The sphere spreads around corners. A creature takes 35 (10d6) necrotic damage and 35 (10d6) cold damage on a failed save, or half as much on a successful one.
