This spell is one of the few cooperative spells that requires one priest to cast the transfer spell, but another priest to use its effect. On one round, a priest (or priests) casts the mystic transfer. The spell is then active for the remaining nine rounds of the turn.
Mystic transfer allows a priest to receive spells from another priest of the same ethos.
Any priest of the same religion can cast a spell and transfer it to a second priest within that spell's maximum range. The spell does not take effect; instead, it is channelled through the mystic transfer into the receiving priest. This priest must immediately cast the spell or pass it to another priest cloaked in a mystic transfer within the spell's range. Any number of transfers can be made in the same round, provided each new recipient is within spell range of the previous recipient. If the spell is not transferred, the spell takes effect.
For example, a 3rd-level priest casts a mystic transfer. On the following round, a 10th-level priest "passes" a flame strike to the 3rd-level priest. The two priests could be 60 yards apart (the maximum range of the flame strike). The 3rd-level priest could then use the flame strike to attack any target within 60 yards, or could pass the spell on to another priest who has an active mystic transfer.
The spell passed by the mystic transfer has the range, area of effect, damage, and other effects equal to the level of the original caster. In the example above, the flame strike would function as if cast by a 10th-level priest.
The mystic transfer does not require concentration. However, on any round in which a priest is receiving and/or transferring a spell, the caster cannot take any other significant action.
A priest can receive spells only from priests who worship the same deity and who specifically target spells to him. Area effect spells may be passed. A priest can never use mystic transfer to pluck an opponent's spells out of the air.

By calling upon his deity, the caster of a spiritual hammer spell brings into existence a field of force shaped vaguely like a hammer. As long as the caster concentrates upon the hammer, it strikes at any opponent within its range, as desired. Each round the caster can choose to attack the same target as the previous round or switch to a new target that he can see anywhere within his maximum range. The spiritual hammer's chance to successfully hit is equal to that of the caster, without any Strength bonuses. In addition, it strikes as a magical weapon with a bonus of +1 for every six experience levels (or fraction) of the spellcaster, up to a total of +3 to the attack roll and +3 to the damage roll for a 13th-level caster. The base damage inflicted when it scores a hit is exactly the same as a normal war hammer (1d4+1 points on opponents of man size or smaller, or 1d4 points on larger opponents, plus the magical bonus). The hammer strikes in the same direction as the caster is facing, so if he is behind the target, all bonuses for rear attack are gained along with the loss of any modifications to the target's AC for shield and Dexterity.
As soon as the caster ceases concentration, the spiritual hammer spell ends. A dispel magic spell that includes either the caster or the force in its area of effect has a chance to dispel the spiritual hammer. If an attacked creature has magic resistance, the resistance is checked the first time the spiritual hammer strikes. If the hammer is successfully resisted, the spell is lost. If not, the hammer has its normal full effect for the duration of the spell.
The material component of this spell is a normal war hammer that the priest must hurl toward opponents while uttering a plea to his deity. The hammer disappears when the spell is cast.

This spell is known as wyvern watch because of the insubstantial haze brought forth by its casting, which vaguely resembles a wyvern. It is typically used to guard some area against intrusion. Any creature approaching within 10 feet of the guarded area may be affected by the "wyvern." Any creature entering the guarded area must roll a successful saving throw vs. spell or stand paralyzed for one round per level of the caster, until freed by the spellcaster, by a dispel magic spell, or by a remove paralysis spell. A successful saving throw indicates that the subject creature was missed by the attack of the wyvernform, and the spell remains in place. As soon as a subject creature is successfully struck by the wyvern-form, the paralysis takes effect and the force of the spell dissipates. The spell force likewise dissipates if no intruder is struck by the wyvern-form for eight hours after the spell is cast. Any creature approaching the space being guarded by the wyvernform may be able to detect its presence before coming close enough to be attacked; this chance of detection is 90% in bright light, 30% in twilight conditions, and 0% in darkness.
The material component is the priest's holy symbol.

This spell allows a priest to plant a section of ground with magically created caltrops.
The spell can create two kinds of caltrops: infantry and cavalry. The first are of small size and are designed to harm foot soldiers. The latter are larger and cause serious damage to cavalry or units composed of size L or larger creatures. Cavalry caltrops are so large that size M or smaller creatures can easily step around them. This prevents damage to infantry units.
Each time a unit moves into a planted area, the unit suffers an attack of AD4 (for infantry caltrops) or AD6 (for cavalry caltrops). Units charging through a planted area suffer double damage. If a unit ends its movement in a caltrop-sown region, it suffers another attack when it moves out of the area.
This spell can create a rectangular field of infantry caltrops up to 160 square yards in area (e.g., 4 yards x 40 yards, 2 yards x 80 yards, etc.), or a field of cavalry caltrops up to 90 square yards in area (e.g., 3 yards x 30 yards, 2 yards x 45 yards, etc.).
Ordinary caltrops make no distinction between friend or foe; all creatures entering a caltrop-sown area suffer the same consequences. The same is true of magical caltrops, with one exception: the casting priest can terminate the spell at any time, causing the caltrops to vanish and leaving the terrain clear.
Unlike normal caltrops, a region sown with magical caltrops cannot be "swept" clear; the magical caltrops remain in place until the spell terminates.
The material component is a golden caltrop.

A surface affected by squeaking floors squeaks loudly when any creature larger than a normal rat (larger than one-half cubic foot or weighing more than three pounds) steps on it or touches it. The spell affects a square whose sides equal the caster's level times 10 feet (a 9th-level priest could affect a square whose sides are 90 feet long).
The squeaks can be heard in a 100-foot radius, regardless of interposing barriers such as walls and doors. The squeaks occur regardless of the surface, whether wood, stone, dirt, or any other solid material. Listeners automatically know the direction of the sounds.
Characters who successfully move silently reduce the radius of the noise to 50 feet.
Those able to fly or otherwise avoid direct contact with the affected surface will not activate the squeaking floor.
The material component is a rusty iron hinge that squeaks when moved.

This cooperative spell requires at least three priests casting the spell simultaneously.
At the time of casting, the priests must be within 10 feet of each other. Upon completion of the spell, the priests sing a single, dissonant chord. The result of the spell depends on the number of voices in the choir.
Trio. In this form, the spell projects a cone of sonic force 120 feet long and 40 feet wide at the base. All creatures within the area of effect must save vs. spells or suffer 2d4 points of damage. Those who successfully save suffer only 1d4 points. Undead suffer a -2 penalty to their saving throws.
Quartet. With four voices, the spell has the same area of effect as described above.
However, all those who fail their saving throw suffer 2d4 points of damage and are deafened for one round. Those who successfully save suffer half damage and are not deafened. Undead creatures are not allowed a saving throw.
Quintet. Five singers produce a chord of major power. All within the area of effect suffer 3d4 points of damage (saving throw for half damage). Undead are not allowed a saving throw. All creatures are deafened for one round. Furthermore, pottery, glassware, crystal, and similar breakable goods must save vs. fall or be shattered.
Ensemble. An ensemble of singers consists of six to ten priests. In this case, the area of effect increases to a cone 180 feet long and 60 feet wide at the base. All creatures within this area suffer 1d4 points of damage per priest and are deafened for 1d4 rounds.
A successful saving throw vs. spell reduces the damage and duration of deafness by half.
Undead creatures of 3 hit dice or less are immediately destroyed. All other undead suffer normal damage, but are not allowed a saving throw. Glass, pottery, crystal, bone, and all wooden items that are the strength of a door or less (chests, tables, chairs, etc.) must save vs. crushing blow or be shattered.
Choir. The most powerful group, a choir, requires eleven or more priests. In this case, the area of effect expands to a cone 300 feet long and 100 feet wide at the base. All within the area of effect suffer 1d6 points of damage per priest to a maximum of 20d6. A saving throw vs. spells reduces the damage to half. Those who fail to save are deafened for 1d10 rounds; those who succeed are deafened only 1d6 rounds. Undead creatures of 5 hit dice or less are immediately destroyed. Undead with more hit dice are not allowed a saving throw. Structures within the area of effect are damaged as if they suffered a direct hit from a catapult (one hit per four priests in the choir). Doors, chests, and other breakable items are instantly shattered.

This spell creates the necessary conditions for devotional energy to be used. For faith magic to work, the priest must create a focus to harness the necessary devotional energy.
This spell creates that focus. A focus cannot function without a source of devotional energy.
The focus gathers devotional energy and reshapes it in order to amplify other spells cast by the priest (or priests). The same energy keeps the focus in existence. If the spell is cast and there is no immediate source of devotional energy within 100 feet, the focus immediately fails.
Once created, most foci cannot be moved. This condition and the need for a constant supply of devotional energy tends to limit the use of foci to temples, churches, monasteries, shrines, and seminaries--permanent structures where followers of the religion gather on a regular basis. Sometimes a focus is created for a special gathering such as a holy day, conclave, grand wedding, or yearly festival.
Not all foci are identical. The particular form of the focus depends on the power and nature of the spell being amplified. All foci can be seen by detect magic. There are three basic types of foci: site, item, and living.
Site foci are connected to a place, whether a room, building, field, or forest. Once cast, the foci cannot be moved. It causes no disturbance in the surroundings; it is invisible and intangible.
Item foci are centered on a single object. Customarily, this object is large and immovable, such as an altar, but it is possible for the focus to be as small as is practical.
The item can be as elaborate or plain as desired, but should have some significance to the religion.
Living foci are the rarest of all types. In this case, the focus is created on a living plant, animal, or person. Detect charm reveals the person is somehow enchanted, although not under the influence of a typical charm spell.
The type of focus created (site, item, or living) depends on the religion and nature of the spell amplified. These choices are listed in Table 3: Focused Spell Effects.
Casting the focus spell is a long and complicated process, accompanied by many ceremonies and rituals. During the day spent casting the spell, the priest will need the assistance of at least two other priests of the same faith. These aides need not memorize the spell (or even be capable of casting it). Their duty is to provide the extra hands and voices needed at specific points of the casting. A large number of worshipers must also be present since the focus requires their energy. Not surprisingly, the casting of this spell is often incorporated into important holy festivals or special occasions.
The duration of the focus is one year. If the devotional energy falls below a minimum level, the spell ends sooner. A focus requires the devotional energy of at least 100 devout worshipers. Lay monks (those dedicated to the religion but not priests) count as two worshipers, while priests (of any level) count as ten. A focus could be maintained by a congregation of 100, a monastery of fifty, or a seminary of as few as 10 priests (or any combination of the above). The focus must receive this energy for at least 10 hours out of every day. If these conditions are not met, the focus weakens. The area of effect of the amplified spell decreases by 20% each day until it fades away completely.
Once the focus is created, the priest or priests have 1 turn in which to cast the desired spell upon the focus. A focus can amplify only one spell, and each item, creature, or place can receive only one focus. Spells that can be cast upon a focus are listed on Table 3.
Table 3: FOCUSED SPELL EFFECTS Possible Focus Spell Type Anti-animal shell S/I/L Anti-plant shell S/I/L Bless S/I Control temperature, 10' radius S* Control winds S/I* Cure disease I/L Cure blindness or deafness I/L Detect poison S/I Detect lie I Detect magic I Dispel evil S/I Endure cold/endure heat S* Know alignment I/L Negative plane protection S/I Protection from evil S/I Protection from lightning S Protections from fire S Purify food and drink I Remove fear S/I/L Remove curse I Repel insects S/I Resist fire/resist cold S Speak with animals S/I/L Tongues S/I True seeing S * The caster must state a desired range (temperature, wind strength, etc.) within the spell's normal limitations at the time it is cast.
Once the spell is cast, the normal duration and area of effect for that spell are ignored.
The focus begins to increase these factors of the spell's power. After one day, the amplified spell reaches its full area of effect. Thereafter, it remains over that area until the focus fails.
The area affected by the focus (and its amplified spell) depends on the level of the caster. The spell expands in a radius from the focus, 20 feet per level of the caster, although it can deliberately be created smaller. Within that area of effect, the amplified spell exerts its normal effect. A 13th-level priest could create a focus up to 260 feet in diameter.
The material components are many, including special vestments, incense, oils, waters, and other equipment the DM deems appropriate. The cost of these materials is never less than 1,000 gp plus 100 gp per level of spell being amplified. These items are given up as offerings to the deity (perhaps to be distributed to the poor), and new ones must be obtained each time the spell is cast.

When the priest evokes a flame strike spell, a vertical column of fire roars downward in the location called for by the caster. Any creatures within the area of effect must roll a saving throw vs. spell. Failure means the creature sustains 6d8 points of damage; otherwise, the damage is halved.
The material component of this spell is a pinch of sulphur.

This powerful cooperative spell is rarely invoked since it requires the concerted effort of six or more high-level priests. The casting effort severely weakens the priests, discouraging casual use of this spell.
To cast the spell, six or more priests must be within a 15-foot radius. Each priest must cast spiritual wrath at the same time. Before beginning the spell, the priests must decide upon the area of effect. The spell causes 10d6+1d6 points of damage per priest casting the spell. (The minimum damage, therefore, is 16d6.) Creatures within the area of effect are allowed a saving throw vs. spell to reduce the damage to half.
The spell strikes as a great wave of force that descends from the sky. Small objects must save vs. crushing blow. Structures suffer damage as if hit by a heavy catapult (2d12). The force of this spell often raises a great cloud of dirt and dust, obscuring the area for 1d4+1 rounds.
The spell's area of effect is determined by the number of casters. Each priest contributes 10 feet to the radius of the spell. Six casters would create a spell with a radius of 60 feet. No more than twelve casters can cooperate to cast this spell (maximum of 22d6 damage and a 120-foot radius area of effect). This converts to an 8-inch circle in the BATTLESYSTEM rules ground scale.
The spell is difficult to cast, physically taxing the spellcasters so much that each caster suffers 3d10 points of damage from the effort. There is no saving throw allowed to avoid this damage.
