Planeshift Tarkir
Spellcasting. The necromancer casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 15):
Aura of Death. The necromancer emanates a deathly aura that extends 30 feet in every direction from its space while it isn't incapacitated. The aura is blocked by total cover. While in the aura, the necromancer and any friendly Undead are immune to the frightened condition and have resistance to radiant damage. Enemies have disadvantage on death saving throws while in the aura.
Multiattack. The necromancer makes three Arcane Burst attacks.
Arcane Burst. Melee or Ranged Spell Attack: +7 to hit, reach 5 ft. or range 120 ft., one target. Hit: 25 (4d10 + 3) necrotic damage.
Grim Harvest (1/Turn). When the necromancer kills a creature with necrotic damage, the necromancer regains 9 (2d8) hit points.
