Chronurgist

Spellcasting. The chronurgist is a 13th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 16, +8 to hit with spell attacks). The chronurgist has the following wizard spells prepared:

Cantrips (at will): fire bolt, light, mage hand, sapping sting

1st level (4 slots): gift of alacrity, mage armor, magic missile, shield

2nd level (3 slots): arcane lock, invisibility

3rd level (3 slots): counterspell, dispel magic, pulse wave

4th level (3 slots): banishment, dimension door, resilient sphere

5th level (2 slots): temporal shunt, wall of force

6th level (1 slot): flesh to stone, globe of invulnerability

7th level (1 slot): teleport

Temporal Awareness. The chronurgist can add its Intelligence modifier (+4) to its initiative rolls.

Arcane Abeyance. When the chronurgist casts a spell using a spell slot of 4th level or lower, it can condense the spell’s magic into a mote. The spell is frozen in time at the moment of casting and held within a gray bead for 1 hour. This bead is a Tiny object with AC 15 and 1 hit point, and it is immune to poison and psychic damage. When the duration ends, or if the bead is destroyed, it vanishes in a flash of light, and the spell is lost. A creature holding the bead can use its action to release the spell within, whereupon the bead disappears. The spell uses the chronurgists spell attack bonus and save DC, and the spell treats the creature who released it as the caster for all other purposes. Once the chronurgist creates a bead with this feature, it can’t do so again until it finishes a short or long rest.

Dagger. Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 4 (1d4 + 2) piercing damage.

Momentary Stasis (4/day). The chronurgist can magically force a Large or smaller creature it can see within 60 feet of it to make a Constitution saving throw (DC: 16). Unless the saving throw is a success, the creature is encased in a field of magical energy until the end of the chronurgist's next turn or until the creature takes any damage. While encased in this way, the creature is incapacitated and has a speed of 0.

Chronal Shift (2/day). The chronurgist can magically exert limited control over the flow of time around a creature. As a reaction, after it or a creature you can see within 30 feet of it makes an attack roll, an ability check, or a saving throw, the chronurgist can force the creature to reroll. It makes this decision after it sees whether the roll succeeds or fails. The target must use the result of the second roll.
