Spell found - from a Dark Elf magic user...

So, the players in my current AD&D game found some interesting treasure (some of it ties into a sort of plot I have been working on for the campaign, as long as it lasts).  One of the items was a unique spell that was written by a Dark Elf magic user.

The spell is a 2nd level MU spell called Plague Rats.  It is for creating a special type of Giant Rat that will be especially effective at destroying or reducing to ruin a small habitation.  If employed by a much higher level magic user, it could be used to destroy a larger habitation, or even large amounts of countryside.  The problem becomes (1) working with giant rats, and (2) avoiding any competent defenders (like NPCs or Characters).

Here is the spell -

Plague Rats (alteration)

Level: 2	Components: V, S, M
Range: 20'	Casting Time: 2 rounds
Duration: Special	Saving Throw: None
Area of Effect: 2d6 Giant Rats

Explanation/Description: This spell is cast on a number of Giant Rats within 20' of the caster.  Upon completion of the spell, the Rats are then infected with a curious plague effect.  If they score a hit in combat on someone, in addition to normal damage, the victim must make a saving throw vs. poison, or become infected by the special effect of this spell.  If the victim fails their poison saving throw, then for four combat rounds following the one during which they were bit, that person will become unnaturally sympathetic to giant rats.  They will not be inclined to attack them, to consider them a threat or menace, or even to want to distance them self from such creatures.  During this time, if they are actually attacked by a giant rat, they can resist the sympathy, and if they successfully roll 1d20 beneath their intelligence, they can attack the giant rat that bit them, during that round.  They must roll each round.  Each time another rat bits the victim, if they fail their saving throw, the effect of this "sympathy poison" is extended another four rounds.  Rats under the influence of this spell have curious luminescent red eyes.  The duration of the spell is based on the level of the caster: Level 3-4 it lasts 3 turns (30 minutes); levels 5-6 it lasts 3 hours; levels 7-8 it lasts 3 days; levels 9+ it is permanent. Material components are a piece of fabric (kerchief, piece of tunic, wound dressing) that was owned/used by a person who died from a disease.  It is consumed during the casting of the spell.

Shadow Snakes - encounter from the Cult of the White Shadow

A particularly troublesome creature is encountered within the Cult of the White Shadow adventure.  The Shadow Snake is that creature - it is a (thankfully) very rare creature that appears in the Valley of the Old Ones, some say spontaneously, but from the prolonged interaction of the material world with magics from the shadow dimensions.  The process is rumor, and is not completely understood, but it at least offers up (however unlikely) an explanation for the presence of the Shadow Snake in the world of the Valley.

From the mad and gibbering descriptions gained from the occasional deranged Cultists that are actually captured alive, it appears as if the the infernal (or shadow) beings that the Cult is trying to summon to our world - the otherworldly and horrid Shadow Wyrms - have imitative lesser beings that the servants of shadow rely on for magical and other purposes.  Those lesser beings are the Shadow Snakes.

A Shadow Wyrm appears as a vast shadowy body of a giant man-wyrm (snake like body, with pairs of clawed legs, at intervals, appearing out of the body; the front does not end with a simple head, but rather with a humanoid torso, with arms, wings out back, and a curious cobra-hooded head, with hollow black eyes).  It is said that to look into the eyes of a Shadow Wyrm is to lose your soul.  In imitation of these vast, horrific beings, a Shadow Snake is somewhat lesser, being man sized in the torso and head, and lacking wings and legs on the lower serpentine body.  In fact, while in the world of the Valley, the Shadow Snakes appear to be (and are) quite solid and material from the torso up, but the serpentine body slowly fades to cloudy wisps of shadow.

When encountered as a hunting party that have come looking for victims for their masters, the Shadow Wyrms, the Shadow Snakes will seek out any intelligent warm blooded victim.  They usually do not give preference to gender, race, profession or ability.  (The exception to this, in the Cult of the White Shadow adventure is that preference will be given to anyone who encounters the curious orange fog).

An encountered party of Shadow Snakes will consist of some number of warriors (as per stats below), for every 10 warriors, there is a Champion (4 hit dice, 2 weapon attacks/round).  For every 20 warriors, there will be two Champions and a Priest (level 7 cleric, servant of Lady of Air).

Shadow-Snake
Num Appearing:  1d6, or as summoned or created.
Alignment: Chaotic Evil
Movement:  120' fly
Armor Class: 6
Hit Dice: 2hd (12hp)
Attacks: 1 weapon attack (shadow spear), 1 bite
Damage: 1d6+2 (shadow spear); 1d8 (bite)
Save: F3
Morale: 10
Treasure: None. 
Special: If the Shadow-Snake bites its victim, make a saving throw vs. poison.  Failure means that the victim becomes allergic to light for the next 24 hours.  Any light source brighter than a dim candle, or a small torch or lantern, will result in painful burns (1d6 damage) every round the victim remains in the light.
The Shadow Spear will do double damage if it strikes in the dark.
The Shadow-Snakes are semi-invisible at all times (and to all modes of site, unless in their home shadow dimension), meaning that those who rely on site in combat are at a -4 to hit them.

Within the Cult of the White Shadow, there are circulated rumors of specific spells used to contact or summon Shadow Snakes.  Certainly, at one time, among the worshipers of the Lady of Air, there were such spells, and communication with the shadow dimension was quite common, as much so as among higher priests of the Westron Church communicating with the Astral plane.

The first such spell is known as the Shadow Clutch.  It allows a single cleric, capable of casting a 4th level spell, to summon 1d6 Shadow Snake warriors, which will remain in the world, doing the bidding of their summoner (with appropriate bribes of blood from warm blooded intelligent victims), for a period of time up to 1 day per level of the spell caster.  The true strength of the spell seems to be when it is simultaneously cast by up to five clerics (a group of five is referred to as a Clutch).  With each additional caster, past the first, the number of dice of Shadow Snake warriors that are retrieved from the shadow dimension is doubled.  So with two clerics, there are 2 dice; with three clerics there are 4 dice; with four clerics there are 8 dice; and with five clerics there are 16 dice worth of Shadow Snakes retrieved.

Shadow Clutch (spell)
Level: 4CL
Duration: 1 day per level of lowest cleric involved
Range: 30'
Successfully casting this spell brings 1d6 Shadow Snake warriors from the Shadow Dimensions to a point within 30' of the caster.  There may be multiple casters, up to five, each of which would have to know and simultaneously cast the spell.  Each additional caster after the first doubles the number of dice worth of Shadow Snake warriors to retrieve.  For every 10 warriors, there will be a Champion (4 hit dice, 2 attacks/round).  For every 20 warriors, there will be a Priest (level 7 cleric, servant of Lady of Air), as well as two Champions.  The casters must be within 10 feet of each while casting.

---

In addition to summoning warriors, it is also possible to subject a hated undividual to the Shadow Hunt, where they will be haunted by Shadow Snakes, their Champions and Priests, as well as Shadow Creatures - all come from the shadow dimensions in order to either destroy or retrieve the poor, unfortunate victim.  This curse can only be lifted by a Remove Curse spell, or greater.

---

Shadow Hunt (spell)
Level: 4MU
Duration: Until removed
Range:50'
A victim cursed by the Shadow Hunt spell will begin to attract beings from the shadow dimensions, who come to the world of the Valley of the Old Ones, specifically to attack and kill (or drag back to the shadow dimensions, in the case of a Shadow Snake priest) the victim.  At random intervals (determined by the DM, but should be at least once per week) new members of the hunt appear somewhere in the vicinity (within 1 mile) of the victim, and will have an uncanny sense as to the victim's location.  The number of Shadow Snakes that arrive is equal to a dice toss of 4d6.  Again, for every 10 warriors, there also appears 1 Champion.  For every 20 warriors, there also appears 1 Priest, in addition to the 2 Champions.  For ever 6 rolled on the dice, there also appears 1 Shadow Creature, serving the leader of the hunt (a Priest if available, if not then a Champion, or one of the Warriors).
