Powerful fungi demons use Puffball Phylacteries to house their souls. The more formidable the demon, the larger and more powerful the Puffball Phylactery is. In fact, not all Puffball Phylacteries are the same. Unusual and bizarre variants are known to exist. In the chaotic evil Outer Planes, entire forests of Puffball Phylacteries exist in “spirit fields”.
Creating a Puffball Phylactery is both costly and time consuming. First, a mundane puffball mushroom is transplanted from a giant fungus forest. Then a cleric well practiced in alchemy, spellcraft, nature and necromancy can grow a Puffball Phylactery in 9 months. After a magic transfiguration process, it is ready for use as a phylactery. The details of such processes are a closely guarded secret, known only to a few cambion clerics called “soul gardeners.”
A Puffball Phylactery can direct its 10 unusually long (20 ft.) tentacles to attack a single target, or up to 10 separate targets at the same time. These thin, whip-like appendages can inflict poison and 1d6 points of damage with each hit, or grapple an opponent to constrict. When not in use, its thin tentacles are retracted inside its body.
Puffball Phylacteries are notoriously difficult to destroy, which is why a demon feels safe placing its soul inside. Puffball Phylacteries are immune to weapons, possess spell immunity, regeneration, deliver poison, and can grasp ten opponents at great distance distance. Flaming oil, acid, normal fire and various other alchemical attacks do normal damage.
Constrict (Ex): To grab a creature the Puffball Phylactery must make a successful grapple. Held creatures can automatically be dealt 2d4 points of damage, plus poison, each round.
Poison (Ex): Fortitude save (DC 24); initial damage permanent Strength 2d8, secondary damage 2d8 temporary Dexterity. This poison is released by the spiky carapace and the tips of all 10 tentacles.
Shatter Weapon (Su): Weapons that strike a Puffball Phylactery automatically receive the same amount of damage (PHB, Sunder — weapon hit points) as a target, inflicting no damage on the puffball. Weapons that are reduced to zero hit points or less are irreparably damaged and shatter into 1d4 pieces. Damage to magic weapons subtracts the amount of its plus (for example, a +3 longsword that would have received 10 points of damage only receives 7 points of damage).
Spiked Carapace (Ex): The high AC of a Puffball Phylactery is due in part to the many gems studding its brown, thick, cracked carapace. Naturally sharp growths jut from between the gems. Contacting the spiked carapace automatically causes 1d4 points of damage, plus poison.
