Incorporeal Movement. The dybbuk can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Magic Resistance. The dybbuk has advantage on saving throws against spells and other magical effects.

Spellcasting. The dybbuk uses Divinity (cha) to cast spells (spell save Difficulty 12, +3 to hit with spell attacks). It has 4 mana, a mana limit of 1, regains all expended mana when it finishes a long rest, and regains half its total mana when it finishes a short rest. It knows the following spells:

At will: teleport (augmented to 3 mana)

Cantrips (at will, 5th-level spellcaster): bone blade, grave rot, life siphon, reanimating word

1 mana: absorb spirit, bone armor, constricting bandage, consumptive field, dampen pain, detect death, false life, fear, life drain, life transference, siphoning strike

1/day: phantasmal force

Violate Corpse. Once on its turn, while possessing a corpse, the dybbuk can make the corpse do something unnatural, such as vomit blood, twist its head all the way around, or cause a quadruped to move as a biped. Any animal or humanoid that sees this behavior must succeed on a Difficulty 12 Will saving throw or become frightened for 1 minute. The frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. A creature that succeeds on a saving throw against this ability is immune to Violate Corpse for 24 hours.

Actions (1)

Tendril. Melee Weapon Attack: +5 to hit. Hit: 13 (2d8 + 4) necrotic damage. If the target is a creature, its maximum health is also reduced by 3 (1d6). This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its maximum health to 0.

Possess Corpse (Recharge 6). The dybbuk disappears into an intact corpse it can see within 1 meter of it. The corpse must be Large or smaller and be that of an animal or a humanoid. The dybbuk is now effectively the possessed creature. Its type becomes undead, though it now looks alive, and it gains a number of temporary health equal to the corpse’s maximum health in life.

While possessing the corpse, the dybbuk retains its health, personality, Intelligence, Wisdom, Charisma, telepathy, and immunity to poison damage, exhausted level, and being charmed and frightened. It otherwise uses the possessed target’s game statistics, gaining access to its knowledge and aptitudes but not its class features, if any.

The possession lasts until the temporary health are lost (at which point the body becomes a corpse once more) or the dybbuk ends its possession on its turn (no action required). When the possession ends, the dybbuk reappears in an unoccupied space within 1 meter of the corpse.

As an action, a column of disembodied gnashing teeth springs forth as a blade in your free hand, screaming and chanting with vigor, and lasts for the duration. You create the blade as a magical dagger, katar, sai, sickle, greatsword, kama, kukri, longsword, scimitar, or shortsword.

The spell ends if you dismiss it on your turn (no action required), if you cast it again, or if you end your turn without the blade in your hand as the blade crumbles to dust.

  • Continuous Teleport. You can expend 2 additional mana to change the duration to 1 minute/mana and on each of your turns before the spell ends, you can use an action to teleport in this way again.

concentration, 1 minute/mana

As two actions, you craft an illusion that takes root in the mind of a creature that you can touch or see within 10 meters. The creature must make a Will saving throw. If the creature is a construct or an undead, the spell has no effect on it.

On a failure, you create a phantasmal object, creature, or other visible phenomenon of your choice that is no larger than a 2-meter cube and that is perceivable only to the target for the duration. The phantasm includes sound, temperature, and other stimuli, also evident only to the creature.

A creature can use an action to examine the phantasm, making a skill check using Insight (Intelligence) against your spell save Difficulty. If the check succeeds, the target realizes that the phantasm is an illusion, and the spell ends.

While a target is affected by the spell, the target treats the phantasm as if it were real. The target rationalizes any illogical outcomes from interacting with the phantasm. For example, a target attempting to walk across a phantasmal bridge that spans a chasm falls once it steps onto the bridge. If the target survives the fall, it still believes that the bridge exists and comes up with some other explanation for its fall—it was pushed, it slipped, or a strong wind (at least 30 kilometers per hour) might have knocked it off.

An affected target is so convinced of the phantasm’s reality that it can even take damage from the illusion. A phantasm created to appear as a creature can attack the target. Similarly, a phantasm created to appear as fire, a pool of acid, or lava can burn the target. Each round on your turn, the phantasm can deal 1d6 psychic damage to the target if it is in the phantasm’s area or within 1 meter of the phantasm, provided that the illusion is of a creature or hazard that could logically deal damage, such as by attacking. The target perceives the damage as a type appropriate to the illusion.
