Upon casting this spell, your body undergoes a horrifying transformation as it takes on the aspects of the undead. Your flesh becomes pallid and cold, your heartbeat slows, and your eyes glow with an eerie, unnatural light.

For the duration of the spell, you gain the following benefits:

• You gain resistance to necrotic damage and immunity to poison damage.
• You are immune to the poisoned condition.
• You do not need to eat, sleep, or breathe.
• You are immune to spells and effects that cause the exhaustion condition.
• While under the effects of Necroform, healing spells and potions have no effect on you. Instead, spells that normally deal necrotic damage will heal you for an amount equal to half the damage they would normally deal. When the spell ends, you must succeed on a Constitution saving throw or gain one level of exhaustion due to the strain of the transformation.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, you can choose one additional benefit from the following options for each level above 4th:

• Spectral Grasp: You can use your action to unleash the necromantic energy within you to grasp a creature with spectral hands. Make a ranged spell attack against a creature you can see within range. On a hit, the target takes 2d6 necrotic damage, and it can’t regain hit points until the start of your next turn. Until then, the hand clings to the target.
• Ethereal Stride: You can move through other creatures and objects as if they were difficult terrain. You take 1d10 force damage if you end your turn inside an object.
• Deathly Visage: Your transformed appearance is terrifying. Creatures of your choice within 30 feet that can see you must succeed on a Wisdom saving throw or become frightened of you until the end of your next turn.
