Although Forbidden magic is foul, to be sure, the Demonology tradition is downright dangerous— not just to the caster, but the whole world, since its spells punch holes in reality to apprehend power from the Void itself.

Spells from this tradition are always perilous to cast and usually have consequences that last far beyond when the magic fades. Even devoted servants of the Demon Lord cast these spells with some trepidation, for they know that by doing so, they bring the world closer to its end.

Claws of Darkness

Target One creature within short range

While the target has this mark, it must use an action to attack on each of its turns, using a charge if necessary. If presented with multiple targets, it must choose the target randomly. Furthermore, at the end of each round, the target must get a success on a Will challenge roll or gain 1 Insanity, though it does not become frightened as a result of gaining Insanity in this way. If the target goes mad from gaining Insanity, it gains 1 Corruption and then reduces its Insanity total by 1d3.

Attack Roll 20+ The target gains 1d3 Insanity, instead of 1 Insanity, when it gets a failure on its Will challenge roll.

At the end of this time, a hole opens in reality to release a tiny demon (Shadow, page 229) that remains until it is destroyed or until you use this function of the spell again. When the demon appears, you make an Intellect attack roll against the demon’s Will. On a success, the demon becomes friendly to you and accompanies you.

At the end of each round, the target must make a Strength challenge roll with 1 bane. On a failure, the target takes 1d6 damage as its belly bulges out until its flesh begins to tear, weeping blood and gore from the fissures.

If the target gets three successes, its belly deflates and a river of corrupted fluids flows from its body for a few minutes.

If the target gets three failures, its belly bursts to release a tiny demon in an open space within 1 yard of it. The target then takes 3d6 damage and gains Insanity equal to its Will score.

The demon acts according to its nature, takes the next available turn, and remains until it’s destroyed.

Possession

Demonology Attack Level 3

Make a Will attack roll with 1 boon against the target’s Defense. On a success, the maw chomps down on the creature, dealing 4d6 damage.

The maw can be attacked. It has Defense 15, Health 40, and it counts as an object. If it is destroyed, the spell ends immediately.

Attack Roll 20+ The maw swallows the creature, drawing it into its space, where it disappears from view. A swallowed creature is held in a bubble extending out into the Void, has total cover from everything, and is blinded, deafened, and immobilized. At the end of each round, the creature must get a success on a Will challenge roll or gain 1 Insanity. If the creature dies while swallowed, its body is sucked into the Void, lost forever. If the creature is still alive when the spell ends, it is spit out to land prone inside the spell’s area. The maw otherwise functions as described above.

Until the spell ends, the demon has full control over the target’s body and can speak using its mouth. You can ask the demon up to three questions. Each time you ask the demon a question, the GM secretly rolls 3d6 and consults the following table to see what the demon does.

3d6Response

Shadow of the Demon Lord

Demonology Attack Level 5

Area A sphere with a radius of 3d6 yards centered on a point you can reach

Duration 3d6 rounds, cannot be ended early


Take 2d6 damage. Magical darkness spreads through the area, rendering it totally obscured. No vision or light can penetrate this darkness.

When you cast the spell, and at the end of each round of the duration, each living creature in the area must make a Will challenge roll. A creature makes the roll with 1 bane for each point of Corruption it has. On a failure, the creature gains 1 Insanity. If the Insanity gain would cause the creature to go mad, it instead becomes possessed as per the possession spell.

In addition, at the end of each round of the duration, the GM chooses 1d6 creatures in the area. Each chosen creature must make an Agility challenge roll. A creature takes 2d6 + 3 damage on a failure, or half that damage on a success. A creature incapacitated by this damage is drawn into the Void and utterly destroyed.

Creatures in the area when you cast the spell must make a Strength challenge roll. A creature takes 6d6 damage on a failure, or half the damage on a success. Any creature incapacitated by the damage dies, collapsing into a pool of formless jelly. Jelly created by this spell evaporates into the Void after 1 hour.

When stunned in this way, the creature throws its head back and makes an awful racket that sounds something like singing. At the end of each round, any creature within 3 yards of a singing creature must get a success on a Will challenge roll or gain 1d6 Insanity. A creature or object in the area of more than one singing creature makes the roll with 1 bane for each creature beyond the first one. If a stunned creature takes any damage, it removes the stunned affliction from itself.
