Aureal Warlock

Holy Aura. Any creature that moves or starts their turn within 10-feet of the Aureal Warlock must succeed a Constitution saving throw (DC = 17) taking 4d6 radiant damage on a failure or half as much on a success.

Multiattack. The Aureal Warlock makes two spell attacks.

Staff. Melee Weapon Attack: +7 to hit, reach 5 ft., 1 target. Hit: 10 (1d6 + 5) [bludgeoning] damage. 

Incinerate. Ranged Spell Attack: +8 to hit, range 120 ft., 1 target. Hit: 21 (3d8) [fire] damage.

Radiant Smite. Ranged Spell Attack: +8 to hit, range 120 ft., 1 target. Hit: 21 (3d8) [radiant] damage.

Pillar of Flame. The Aureal Warlock can create a 5-foot wide, 30-foot tall pillar of flame centered on a point they can see within 90-feet. Any creature within the Pillar of Flame must succeed a DC 17 Constitution saving throw taking 8d6 fire damage on a failure, or half as much on a success. The Aureal Warlock can move their Pillar of Flame up to 30 feet on their turn. 

Blink. As a reaction to being attacked, the Aureal Warlock can perform a short-range teleport disappearing and reappearing at a position of their choice up to 60-feet away. Moving in this fashion does not provoke attacks of opportunity. 

Shield. As a reaction to being attacked, the Aureal Warlock can create a magical shield in order to protect themselves. Doing so magically increased their armor class by 2 until the start of their next turn.
