Animal

Creo Animal

Arise, My Hounds

CrAn 100 Ritual

R: Voice, D: Momentary, T: Group

When this spell is cast, the caster must name up to 10 animals he wishes to resurrect, calling upon them to return to him. If within Voice range, they will be resurrected, fully restored to life and health. It is not known whether this spell can resurrect magical animals, and if so to what Might.

This spell was supposedly transcribed from the lips a Faerie Lord of Summer Dark. His “hounds” were as big as a small house. He used his powers to constantly resurrect them in a Great Hunt, but the allusion that his powers are Hermetic in nature is dubious at best.

(Base 75, +2 Voice, +2 Group, +1 size for the size of an elephant (size +4 = +1 from base Individual, +3 from magnitude))

Intellego Animal

Guardian of the Forest

InAn 100 Ritual

R: Arcane Connection, D: Year, T: Boundary

The caster gains complete insight into the mind of every animal within the boundary (up to about 3 miles in diameter), no matter where he is at the moment. He can read all their thoughts, emotions, and memories, and is privy to all their sensations. The caster is constantly aware of any animal within the boundary, and of what each is feeling and sensing. This is focused on the boundary, and not on specific animals (the boundary is treated as a dynamic container). This awareness even extends to his dreams, which are filled with fragments of their sensations.

The sheer strangeness of the experience leaves the caster harrowed. The spell is always considered to be a constant, high power, effect not designed for him (even if he invented and casts it). The spell thus grants six warping points: 1 when it is cast, +1 per season, +1 at the end of the year.

This dubious spell was supposedly developed by the renowned Derrezan filius Bjornaer. It is said it was this spell that drove him to his insanity, as even he was unable to endure the multitudes of perceptions flowing through his mind. This spell is rumored to exist in the library of Crintera, but none has used it in living memory.

(Base 20, +4 Arcane Connection, +4 Year, +4 Boundary, +4 size)

Muto Animal

A Wing of Pegasi

MuAn 70 Ritual

R: Voice, D: Moon, T: Group

The spell transforms up 10 horses to Pegasi, making them sprout wings. It may take a while for the beast to learn how to use them properly. The animal does not gain a Magic Might score, but is somewhat magical in nature and will not be daunted by the Gift.

This spell was discovered as cave carvings in a cave on a lonely Greek isle, and successfully translated into an Hermetic Ritual by the great genius Jerome of Bonisagus. It is believed that the original was penned by a giant, who used the spell to create flying cavalry.

(Base 25, +2 Voice, +3 Moon, +2 Group, +1 size for horse, +1 to accomodate Gift)

Perdo Animal

The Silent Forest

PeAn 85 Ritual

R: Sight, D: Momentary, T: Boundary

This spell kills every animal within the targeted boundary, which can be up to 3 miles in diameter.

This spell was invented by Apromor filius Flambeau as part of a wizard’s war with a Bjornaer wizard. He cast it while flying above the forests of Russia. Several forests in Russia’s northern reaches were decimated in this war. Ironically, his opponent survived.

(Base 30, +3 Sight, +4 Boundary, +4 size)

Rego Animal

Free the Army of Beasts

ReAn 70 Ritual

R: Sight, D: Moon, T: Group

The caster gains complete control over a group of horses within his sight. The group can be huge, up to a 1000 horses, such as "all the horses in the army". By making a Concentration check of 9+ he can mentally command them to do any action (the storyguide should determine what commands they can understand, and what requires constant supervision). Even after the spell is cast, for a duration of one moon, the caster can regain control with a successful Concentration check, giving the beasts new commands.

The horses will obey the caster’s command without hesitation. If the command may result in bringing them harm (such as ordering them to jump off a cliff), they may resist with a Stamina roll of 15+. A success breaks the spell.

This spell was invented by Denera of Bjornaer as part of her now-infamous defense of the Albigensians. She used it to control the horses of the crusader armies, dispersing their army and greatly assisting the heretics.

(Base 15, +3 Sight, +3 Moon, +2 Group, +1 size for horse, +2 size for more horses)

Corpus

Muto Corpus

Cloak of the Misty Spirit

MuCo 40; Requisite: Au

R: Personal, D: Sun, T: Individual

You place a funeral shroud over yourself, and change into a thin ghostly form. The form is still visibly you, but nearly translucent and appears ghostly. In this form you can fly at walking speed without incurring any Fatigue, and can slip through cracks much like air. You are nearly immune to physical sources of damage, that pass through your airy body harmlessly, but are vulnerable to high-winds, that may tear your body. You suffer the effects of deprivation normally, and the effects of heat and fire too, though you are immune to cold. You can change back at will, ending the spell, by removing the shroud.

(B 30, +2 Sun)

This spell is somewhat similar to the Form of the Zephyr from Transforming Mythic Europe.

Herbam

Creo Herbam

Trap of the Entwining Growth

CrHe 15

As Trap of the Entwining Vines, but it induces growth of branches and vines from existing wood (living or dead). If grown from a wooden floor, the effect is the same as Trap of the Entwining Vines (a circle 2 paces across, and up 6 feet high). If grown from trees, a fence, or so on, the effect may be more limited in extent.

(Base 1, +2 Voice, +2 Sun, +2 Group)

Rego Herbam

Petrification of the Animated Tree

ReHe 30

R: Voice, D: Diameter, T: Ind

This spell holds an animated tree or wooden object in place, freezing it in its current position and posture – even in midair. The spell was invented to freeze animated trees, but can work on a wooden or mostly-wooden projectile as a fast-cast spell. It can freeze a large tree (up to Size +6), or a wooden object such as a large boat or a small ship.

(Base 5, +2 Voice, +1 Diameter, +2 size)

Base 5 "Move a plant or plant product slowly in any direction you please, even if the target is unsupported" used.

Imaginem

Perdo Imaginem

Hade's Gift of Invisibility

Pe(Cr,Re)Im(Ig) 35

R: Personal, D: Sun, T: Ind

This spell destroys the caster's ability to affect sight. In addition, it distorts the images around him so that he appears to not be there, making him invisibile. The spell even creates light to perfectly compensate for any shadows the caster would otherwise have made.

In Greek mythos, the Cyclops gifted Hades with the Helm of Invisibility, which he used to defeat the titans. This spell was created to see how difficult making something invisible could plausibly be under Hermetic spell guidelines, ignoring the Veil of Invisibility spell itself. While not very high level, the many requisites do make it somewhat more difficult to cast.

(Base 4, +2 sun, +1 changing images, +1 Re requisite, +1 Cr, +1 Ig, +1 intricate effect)

Mentem

Muto Mentem

Vision of the Haunting Spirit

MuMe(Im) 25

R: Touch, D: Concentration, T: Ind; Requisites: Imaginem

A touched spirit becomes visible, although it might remain unseen if hiding behind something. This includes the spirits of living people, which appear as the person normally does. If the person is invisible or otherwise changed from his normal shape, his normal appearance is superimposed on his current appearance.

(Base 15, +1 Touch, +1 Concentration)

This is a variant of Vision of the Hauntins Spirits core rulebook spell, just with lower spell parameters.

Rego Mentem

Trap of the Enigmatic Labyrinth

ReMe 45

R: Voice, D: Special, T: Ind

Traps the target within a Criamon labyrinth in his own mind. The person sees himself standing at the center of a circular mandala-like maze, and is consumed with the need to get out following its lines. If the character doesn't have Enigmatic Wisdom, exiting the Labyrinth requires 8 hours; half the time per Enigmatic Wisdom level.

While engaged in the labyrinth, the character is unable to take any action except to seek a path out of it.

(B 20 as 'give a person a complex command', +2 voice, +3 Special duration similar to Sun. Duration halved from the 16 hours of the Criamon labyrinth meditations in Houses of Hermes: Mystery Cults as that's too long for "Sun". The "mandala" is a cosmetic effect only, requiring no requisite or added magnitudes.)

Summon the Fallen Company

ReMe 50

R: Arcane Connection, D: Concentration, T: Group

The spell summons a company of ghosts to which the caster has an arcane connection. This spell can only summon ghosts from Mythic Europe (including regios), it cannot reach into the Realms of Power.

(Base 15, +4 Arc, +1 Conc, +2 Group)

This is somewhat similar to the Call the Fallen Eagles from the Mist spell from Houses of Hermes: True Lineages. As it isn't a Ritual, it cannot summon spirits from the Realms, including the spirits of the dead if they've passed on to their afterlife.

Terram

Rego Terram

Petrification of the Moving Stone

ReTe 20

R: Voice, D: Diameter, T: Ind

This spell holds an earth or stone target in place, freezing it in its current position and posture – even in midair. The spell was invented to freeze stone-golems in their place, but can work on a stone projectile as a fast-cast spell. It can freeze a stone creature of up to Size +3 (10 cubic paces), assuming it penetrates any magic resistance.

(Base 3, +1 unsupported, +2 Voice, +1 Diameter, +1 size)

Base 3 "control or move dirt in a very unnatural fashion" used. A +1 magnitude for stone is presumably not needed, as keeping it in place should be just as easy as "simply being moved from one place to another".

Vim

Perdo Vim

Crushing Hammer of the Hearth

Pe(Re)Vi Gen

R: Touch, D: Year, T: Boundary; Ritual

Reduce the casting total of all supernatural powers, from any Realm, by half the (spell level -9 magnitudes) of the spell. This includes Hermetic spellcasting, as well as the use of Methods and Powers and similar casting totals. The penetration of any Power is also lowered by this amount. The use of any supernatural Ability is penalized by one third of this amount.

Magic items are also affected. Reduce their penetration.

Excluded from this effect is any magic created by magi who participated in the casting of the spell, or that received a token (as per Aegis of the Hearth), as well as the magic of any magic item present within the boundary at the time of casting.

This spell was created by Trisagus of Bonisagus, in a poor attempt of recreating Notatus' great achievement by more Hermetic means. The great difficulty of casting this spell (requiring two Techniques), and its weak effects, are a testament to Notatus' brilliance.

(Base Gen, +1 Touch, +4 Year, +4 Boundary, +3 extra Realms, +1 Re)

Rego vim

Hermetic Aegis of the Hearth

ReVi Gen

R: Touch, D: Year, T: Boundary; Ritual

This ritual protects a covenant much like a Parma Magica protects a magus.

If any spell is cast toward the Aegis (originating from outside it) by any magus who was not involved in casting the Aegis ritual, the Aegis resists the spell. The spell must penetrate a Magic Resistance equal to the level of the aegis, or it is blocked and prevented from entering or affecting the protected Boundary. The aegis is able to block foreign Intellego spells in this manner, even if they cannot normally be blocked by a Parma Magica.

Furthermore, spells that bring objects into the Aegis, including teleportation spells such as The Seven-League Stride, are also blocked unless the caster was involved in the ritual. If the foreign spell cannot penetrate a magic resistance equal to the level of the Aegis, a teleportation spell simply fails, and a spell that moves its target fails to move it past the boundary's border.

Effects from enchanted devices are resisted by the Aegis unless the item was within the Aegis at the time of casting, or was created within the Aegis by someone who was part of the ritual or has a token (see below). Powers from supernatural creatures are resisted. Creatures with a Might score cannot enter the area protected by the Aegis unless they have a higher Might than the Aegis’s level. Note that the aegis need not penetrate to have this effect, as penetration is already included in this effect's calculation.

Creatures without a Might score can enter the protected area freely. However, the aegis will block the entrance of any magical effect that fails to penetrate it. For example, a person under a veil of invisibility may find it impossible to enter the aegis, unless the spell's penetration surpasses the Aegis level. There is, however, a major exception to this rule – if the creature has Magic Resistance that exceeds the aegis level, the aegis cannot prevent him from entering, regardless of what spells or effects are active upon him. The aegis will also similarly never block the entrance of a magus that participated in its casting, and will thus ignore any active effects on him.

Note that for this purpose, a longevity ritual, familiar bond, or talisman bond do not count as active effects, and so the aegis will not block their entrance.

Creatures and persons may be brought within the Aegis, if they are formally invited by a magus who participated in its casting and given a token to represent the invitation. These tokens are used during the casting of the ritual, and are an integral part of it. An invited person is never blocked or affected by the aegis, just as if he was a magus who participated in its casting. The invitation may be withdrawn at any time. A magus may only expel specific, known, individuals, and in their presence. This does not require retrieving the token. The invitation and expulsion must both be issued by magi who participated in the ritual, but not necessarily by the same magus. Withdrawing an invitation will not expel the person beyond the Aegis, but will prevent them from re-entering after they leave (unless their Might or Magic Resistance is high enough).

When approaching the border of an Aegis, a magical person (including a Hermetic magus) feels a slight tingle in the extremities. For those of Second Sight or Magic Sensitivity, the Aegis sometimes appears as a glistening dome.

This variant of the Order's Aegis of the Hearth was created as a Minor Breakthrough by Trisagus, a Bonisagus magus, in a poor attempt to recreate Notatus' breakthrough. It is supposedly more "Hermetic" - but critically lacks the Perdo effects the standard Aegis provides.

(Breakthrough effect; should be Base Gen, +1 Touch, +4 Year, +4 Boundary. This is an attempt to make the Aegis spell conform more to standard magic theory and magic resistance rules.)

Hammer of the Hearth

ReVi Gen

R: Touch, D: Year, T: Boundary; Ritual

This spell suppresses all spells or effects cast by foreign magi whose level is less than or equal to (level – 5 magnitudes) of the Hammer. This includes ongoing effects, as well as new spells cast while the Hammer is active. Excluded are the spells cast by all magi that participated in the casting of the Hammer ritual.

Magic items are similarly affected. Effects of (level -5 magnitudes) are suppressed. Excluded from this are any effects created by the magi participating in casting the ritual, or by items present in the boundary at the time of casting.

Powers are similarly affected. The level of the power is at most the creature's Might, and usually equal to the (Might Point cost) x 5.

The Hammer cannot affect Personal powers or spells, or spells already active on a person or creature, unless it penetrates the creature or caster's Magic Resistance. This includes effects affecting familiars or talismans. The Hammer does not affect the Parma Magica, longevity rituals, or familiar bonds (but bond enchantments may be affected, if the Hammer penetrates), and does not sever arcane connections.

Creatures or persons can be invited into the boundary using tokens, much like in the Aegis of the Hearth spell. They will find their spells, powers, and enchantments are not affected by the Hammer. The invitation can be rescidned, again just like the Aegis of the Hearth.

This spell was creates by Trisagus of Bonisagus. It is meant to be cast immediately after the Hermetic Aegis of the Hearth, so that together the two would provide protection similar to that of the standard Aegis of the Hearth.

(Base Gen, +1 Touch, +4 Year, +4 Boundary, +1 specificity)
