Zythan

Being within 5 feet of a hostile creature doesn't impose disadvantage on Zythan's ranged attack rolls.

Zythan has advantage on saving throws against spells and other magical effects.

Zythan casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 18).

At will: Arcane Eye, Detect Magic, Detect Thoughts, Fly, Light, Locate Object, Mage Armor, Mage Hand, Message, Prestidigitation

1/day: Cone of Cold, Foresight, Stoneskin, Rary's telepathic bond, True Seeing

Zythan makes three Dagger or Arcane Burst attacks.

Melee or Ranged Weapon Attack: +7 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 4 (1d4 + 2) piercing damage.

Ranged Spell Attack: +10 to hit, range 120 ft., one target. Hit: 27 (4d10 + 5) radiant damage.

Zythan causes a disruption in arcane energies in a 300-foot line that is 5 feet wide. Each creature in the line must make a DC 18 Constitution saving throw, taking 65 (10d12) radiant damage on a failed save, or half as much damage on a successful one.

As a reaction to a creature Zythan can see making an attack roll, a saving throw, or an ability check, Zythan rolls a d20 and chooses whether to use that roll in place of the original roll.
