Vitrioli are enchanted monsters native to the Para-elemental Plane of Ooze. They do not respond to conjurations by any known spell, but can be summoned by use of a special liquid. Though anyone can use the liquid, only its creator can command the vitrioli only when they first appear.
Vitrioli appear on the Prime Plane as tiny faceless humanoids that appear to be made of sand. They glow with a dim green light. Excitable even on their home plane, they become enraged when drawn from it, attacking any living thing they see, except each other. All details here apply only to their Prime Plane forms, as they have thus far eluded close observation in their native environment.
A Vitriolus explodes when hit or when it hits an opponent. The explosion has a 5-foot radius, and produces both fire and acid damage. Each victim in the area must make two Saving Throws vs. Breath Weapon. The fire damage is 1d8 points plus the original hit points of the Vitriolus. The acid damage is 2d4 points. A successful saving throw reduces damage to one-half in each case. Failure of either saving throw requires further saving throws for items carried. The explosion can also cause structural damage: I point to wood, 1/2 point to metal, but no damage to earth or stone. The Vitriolus is immune to fire and acid-based attacks. It loses 1 hit point per 6 hours spent away from its home plane, disintegrating when reaching 0 hit points.
Vitrioliquid: A cleric may create a vial of this rare fluid by combining three types of acid, swamp water, and graveyard soil in the proper proportions. The following spells must be cast on the mixture, in this order: light, flame strike, animate object, command, implore, and quest. Some knowledge of the Para-elemental Plane of Ooze is also required. There is a 30% chance that the finished liquid suddenly and permanently drains 1 point of Constitution from the caster, probably because of some force emanating from the monsters' home plane. Such damage cannot be avoided except by chance, though it can be repaired in the usual ways.
Vitrioliquid is always kept in a glass vial, for glass is the only known substance through which the liquid cannot eat. If the entire potion is poured out or the vial broken on earth or stone,
10-100 vitrioli appear from the spot at the rate of one each two segments (5 per round). If only part of the liquid is used, the number of creatures appearing is proportionately fewer. If the liquid is poured into a swamp or other mixture of water and abundant plant life, the number of creatures summoned is greater by tenfold (100- 1,000), as the rich muck beneath the water somehow enhances the effect. If the liquid is poured out onto any other substance except glass, it eats its way through and continues downward until it reaches stone or earth.
A sip of vitrioliquid causes 1-6 points of damage; drinking more than a sip is extremely dangerous. The foolish imbiber must roll ld20; a result of 1-19 indicates death (immediate reduction to -20 hit points), and a result of 20 means that the victim survives the experience but with only 14 hit points remaining. This effect supercedes and negates the usual effects of the liquid; no creatures are summoned, and the liquid does not eat its way out of the victim.
