Special Traits

• Arcane Dismantlement. Whenever the magus successfully dispels or counters a spell with dispel magic, counterspell, or a similar spell, it can make an Intelligence (Arcana) check against a DC equal to the spell’s level + the spell save DC of the spell’s caster. On a success, the magus recovers an expended spell slot equal to or less than the dispelled spell’s level.
• Legendary Resistance (3/Day). If the magus fails a saving throw, it can choose to succeed instead.
• Rejuvenation. If it has a phylactery, the destroyed magus gains a new body in 1d10 days, regaining all its hit points and becoming active again. The new body appears within 5 feet of the phylactery.
• Spellcasting. The magus is an 18th level spellcaster. Its spellcasting ability is Intelligence (spell save DC 20, +12 to hit with spell attacks). The magus has the following wizard spells prepared:
• Cantrips (at will): acid splash, mage hand, prestidigitation
• 1st level (4 slots): detect magic, magic missile, shield
• 2nd level (3 slots): detect thoughts, invisibility, mirror image
• 3rd level (3 slots): animate dead, counterspell, dispel magic, fireball
• 4th level (3 slots): blight, confusion, dimension door
• 5th level (3 slots): cone of cold, scrying
• 6th level (1 slot): disintegrate, globe of invulnerability
• 7th level (1 slot): finger of death, plane shift
• 8th level (1 slot): dominate monster, power word stun
• 9th level (1 slot): power word kill
• Turn Resistance. The magus has advantage on saving throws against any effect that turns undead.

Actions

• Paralyzing Touch. Melee Weapon Attack: +12 to hit, reach 5 ft., one creature. Hit: 10 (3d6) cold damage, and the target must succeed on a DC 19 Constitution saving throw, or be paralyzed for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Legendary Actions

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

• Cantrip. The magus casts a cantrip.
• Paralyzing Touch (Costs 2 Actions). The magus uses its Paralyzing Touch.
• Sense Weakness (Costs 2 Actions). The magus telepathically probes a creature it can see, within the range of its telepathy, for its strengths and weaknesses. The target must succeed on a DC 19 Charisma saving throw, or the magus learns of the target’s damage vulnerabilities, resistances, and immunities, as well as condition immunities and the exact number of hit points remaining.
• Frightening Apocrypha (Costs 3 Actions). The magus telepathically focuses a stream of forbidden knowledge on one creature it can see within 20 feet of it. The target must succeed on a DC 19 Wisdom saving throw, or become frightened for 1 minute. While frightened, the creature has disadvantage on Intelligence, Wisdom, and Charisma saving throws against the magus’ wizard spells. The frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target’s saving throw is successful, or the effect ends for it, the target has advantage on Intelligence, Wisdom, and Charisma saving throws against the magus’ spells until the next time it fails to save against one of them, and is immune to the magus’ gaze for the next 24 hours.
