Voidwracked Mage

Dabbling in void magic often leads to unexpected and horrific results. A voidwracked mage is a spellcaster whose reckless experimentation has accidentally fused it with a portal to the Void itself. The driving purpose of a voidwracked mage is to increase the total entropy of the multiverse by consuming creatures with the event horizon to which it is fused. A voidwracked mage often serves more powerful void-touched creatures.

Special Traits

• Event Horizon. Creatures pulled through the event horizon via the voidwracked mage’s Accretion ability or that pass through it willingly become trapped in the void. A trapped creature is unable to breathe and can’t cast spells with verbal components. At the end of its turn, the trapped creature takes 14 (4d6) necrotic damage and 9 (2d8) cold damage. A trapped creature that is not incapacitated can escape if a rope or long pole is passed to it from the outside. Either the creature itself or an ally outside of the event horizon must succeed on a DC 15 Strength (Athletics) check to pull the creature out. The voidwracked mage can also release a trapped creature as an action.
• Horizon Collapse. When the voidwracked mage is reduced to 0 hp, its event horizon collapses after 1 minute. Creatures trapped in the void when the event horizon collapses are lost and can only be restored by a wish or true resurrection spell.
• Insane. The voidwracked mage has advantage on saving throws against being charmed or frightened.
• Spellcasting. The voidwracked mage is a 9th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 16, +8 to hit with spell attacks). The voidwracked mage has the following wizard spells prepared:
  • Cantrips (at will): chill touch, mage hand, prestidigitation, ray of frost
  • 1st level (4 slots): cause fear, magic missile, ray of sickness, shield
  • 2nd level (3 slots): darkness, misty step, scorching ray
  • 3rd level (3 slots): counterspell, dispel magic, fireball
  • 4th level (3 slots): black tentacles, blight
  • 5th level (1 slot): cone of cold

Actions

• Void Touch. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 14 (4d6) necrotic damage.
• Accretion (Recharge 5–6). The voidwracked mage creates a strong gravitational pull in a 20-foot cone. Each creature in that area must make a DC 15 Strength saving throw. On a failure, the creature takes 28 (8d6) force damage and is pulled through the voidwracked mage’s event horizon. On a success, the creature takes half the damage and is knocked prone but isn’t pulled into the event horizon.
