Vael'Estas

Spellcasting. Vael'Estas is a 10th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). Vael'Estas has following spells prepared:

1st level (4 slots): command, shield of faith, thunderous smite 

2nd level (3 slots): branding smite, find steed

3rd level (2 slots): blinding smite, dispel magic

Multiattack. Vael'Estas uses Majesty of Darkness, if it is available, and makes one melee weapon attack; or makes two melee weapon attacks.

Glaive (Yurgaleg). Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 5) slashing damage.  When this creature hits with this attack each other creature, within 15' must make a DC 14 constitution saving throw or take 4(1d6) necrotic damage, healing this creature for half the total damage dealt by this attack. Creatures slain by this attack rise as zombies under this creature's control in 1d4 turns.

Hurl Moonlight. Ranged Weapon Attack: +7 to hit, range 150 ft., one target. Hit: 19 (3d12) cold damage and the target must succeed on a DC 13 CON saving throw or be blinded until the end of its next turn. 

Majesty of Darkness (Recharge 5-6). Vael'Estas emits a sinister burst of darkness. All creatures within 30 ft. and in direct line of sight of him take 19 (3d12) necrotic damage and must make a DC 14 CON saving throw. Those who fail are blinded for 2 rounds, those who succeed are frightened for 2 rounds. Any creature that succeeds against this attack is immune to further blind/frightened from this ability (but not the damage).

Command. As a bonus action Vael'Estas can command all other Moon-Elves within 15 ft. to make a single melee attack against a target in range.

Shadowform. As a reaction Vael'Estas can become incorporeal as a shadow and move up to his movement speed. While in this form he is immune to opportunity attacks, has resistance to non-magical damage, advantage on saving throws against spells and abilities, can occupy the same space as other creatures and can move through any space as long as there is a gap of any size. At the end of this movement he takes his original form. If he is occupying the same space as another creature he is moved 5 ft in a random direction and is prone. If this movement ends in a space too small for him to occupy he takes 15(2d8)+5 force damage and is moved to the nearest occupiable space and is prone.
