MARROW Magic II: Electric Boogaloo

 MARROW MAGIC

For a long time I’ve been struggling with how to handle magic in MARROW. I’ve never found or developed a system where I was satisfied with the depth, flexibility, and consistency of a spellcasting system and how it fit into the rest of MARROW. Here’s my first draft at something coherent and usable.

CASTING A SPELL

To cast a SPELL, roll...

INT: If you’re using an object, like a spellbook or wand, to cast

WIS: If you’re calling upon another entity to use your magic

CHA: If the magic was inside you all along…

If you CRIT, you cast the SPELL successfully without USE. If you succeed, you cast the SPELL, but USE it. If you fail, the SPELL fizzles, but you don’t USE it. If you FUMBLE, the SPELL flops, you USE it, and things usually go sideways.

PUSH

Once you’ve cast a SPELL, you can voluntarily take STRESS to PUSH it. There’s no limit to the STRESS you can take, but be careful- PUSH yourself too hard and things might get out of hand fast! There are three axes upon which you can PUSH yourself: Duration, Versatility, and Intensity.

	1 STRESS	2 STRESS	3 STRESS
DURATION	+d4 TURNS/ROUNDS	+d4 days	Eternal
VERSATILITY	Tiny bend in use	Reasonable enough use	Vaguely similar at best
INTENSITY	Perceptible boost	Significant boost	Mighty power!
(Extra damage)	+1	+2	+4
(Decreased casting time)	Halved	Quartered	Instantaneous

You can also PUSH yourself to the limit, casting epic magics that define eras. Nothing is outside of your grasp, from time reversal to deicide to mass resurrection. However, when you do so, you die with no hope of return, or suffer a worse fate. There is no escape from the scales of death.

USE

Depending on the form your SPELL takes, USE looks different. Here’s some examples:

STR: Wands, staves, orbs, rods, scrolls, spellbooks, and all sorts of eldritch bric-a-brac can contain SPELLS in STR slots. Most of the time, they have one SPELL apiece, with as many as 3 or 4 in a more powerful object, like an archmage’s book. They also contain a set pool of USE upon finding (d20, if you’re in a pinch). You can also use that USE as STRESS in the case of PUSHING SPELLS the object casts. These objects FUMBLE like anything else!

DEX: Magical tattoos, hereditary witchery, and parasites from other dimensions all might be sources of SPELLS that occupy DEX slots. Whenever you take USE from a SPELL cast in this way, take 1 FATIGUE instead. If you FUMBLE, instead take d6 FATIGUE, or induce an arcane catastrophe.

WIS: Most SPELLS as people know them, memorized bundles of arcane energy, are stored in WIS slots. If an ABILITY grants SPELLS, this is the form they take. When a SPELL takes USE, it instead is destroyed, no longer occupying a SLOT- you have forgotten the ancient rune-words you need for your invocation.

CHA: Most of the time, SPELLS themselves won’t occupy CHA slots, but instead, many ABILITIES grant SPELLS in various forms. However, a SPELL so mighty that attaches itself to the magician’s identity, something as world-shattering as Wish or Apocalypse...

TOKENS

Every SPELL on Aeros has an associated TOKEN. It might be a common item (a penny with two “heads” faces, a cat’s whiskers), or something unique and magical (a cockatrice egg, the Apocrypha Orb). If you have the appropriate TOKEN while you cast a SPELL, make your casting roll with ADVANTAGE.

D10 random TOKENS:

1 A spool of silver

2 A dream about the ocean in a bottle

3 A Nemidian rune-rock

4 A red mole’s molehill

5 The sword of Khar Vendis

6 A green glass eye

7 A staff carved from the world’s oldest tree

8 An angel’s toenail

9 A child’s favorite marble

10 A lightning bolt

PROCEDURE

• Roll to cast the SPELL

• If you have a TOKEN, roll with ADVANTAGE

• Allies can roll INT to assist, if they succeed, you roll with ADVANTAGE

• Expend USE as needed

• If you failed your roll, stop after this step!

• PUSH yourself, if you dare

• The effect takes hold

VULGAR ARCANA

This is the equivalent of your basic SPELL list. Roll a d4 (for one of the four types of rune magic) and a d8 to determine a random SPELL. SPELLS are described as follows:

Spell Name. Spell description, in terse terms. (TOKEN here)

1 RAVEN

1 Swarm. A scratching mass of claws and craws deals 2 WOUNDS and causes a lot of havoc before scattering to the wind once more. (Stillborn animal with a conjoined twin)

2 Feather Cloak. This cloak woven from the blackness between the stars clads you for a TURN; while wearing it, you’re only perceptible by magical entities. (Broken humerus)

3 Word of Murder. Call out in blasphemous tones and point at someone. A feather tattoo appears on their body. It will kill them in 13 days. (The skull of a Demon Lord)

4 Bird Soul. Animate an object with the spirit of a dead bird for a TURN. Good luck getting it to do anything useful. (A tea kettle filled with boiling blood)

5 Crowsflesh. You take a half-avian form for a TURN, your toes morphing into claws and your arms into atavistic wings of jet. (A statuette carved from a petrified tree)

6 Warp. The flesh of your target blooms and calcifies under your touch, inducing a random MUTATION. (A Moon Orchid)

7 Cry. Your mournful laments are understood by all who hear, so long as they are utterly pessimistic. Choose one living creature, you two can converse for a TURN. (Tears)

8 Psychopomp. Kill someone. You can pull the soul of a FRIEND dead for no more than a day into that body. That body can never heal through natural means. (A golden scythe)

OTHER POSSIBLE SPELLS: Wardenship of the Flock, Bird Familiar, Beast Command, Growth

2 MOON

1 Terraform. Everything FAR from you becomes a lunar biome: salt spires, crater-valley, fungal pit, sulphur sea, sugar-hive, the Moon Monarch’s Manor, or another. (Moon rock)

2 Crown of the Lunar Queen. A halo of glowing moon rock appears above a touched target’s head; they obey your commands for d4 ROUNDS. (Crown of a dead ruler)

3 Moon’s Nimbus. Moonlight shines around you for a TURN. It acts as natural sunlight, and no creature can enter the light without your permission. (Blue flame)

4 Regality of Moths. For a TURN, people assume you’re important, and you can levitate a handspan off the floor. (A living moth the size of your head)

5 Bind Moon-Beast. 50% this is some wildlife, like a Trilobite or a Stone Flower. 40% this is an intelligent member of the Moon Court, like the Bubble Wizards of t’Keem. 10% this is the Moon Monarch herself, who can grant wishes or bestow knighthoods. (Mithril bell)

6 Phase Change. The moon immediately changes to your choice of phase, or if it’s during the day, a solar eclipse occurs, lasting a TURN. Don’t overthink it. (A silver blade)

7 Melancholy Melody of the Moon Monarch. For a TURN, the minds of all who hear you sing are filled with thoughts of the worst outcomes of their actions. (Musical instrument)

8 Lunar Lock. Spend d4 ROUNDS carving zodiac symbols on a doorway or entrance to make it impassable for a TURN. (A key made for no door)

OTHER POSSIBLE SPELLS: Lycanthropy, Meteor, Zodiac Invocation, Solar Wrath, Read Stars

3 GLASS

1 Lacerating Carapace. You get +1 DEF for d4 ROUNDS as your skin sprouts broken flesh-shards. When something CLOSE hits you, it takes 1 WOUND. (Trilobite shell)

2 Prism. Create a monochromatic illusion your size or smaller for d4 ROUNDS. (Prism)

3 Sanguine Signatory. Take a WOUND to write a command in blood. As long as it’s wet (usually a TURN), all who read it must follow it. (A Devil’s quill pen)

4 Oubliette. Open a portal to a random place in the cosmos; a target you touch is banished therein for d4 ROUNDS or until a countercharm is performed. (Gold manacles)

5 Invulnerability. Touch an object to make it impervious to damage or FUMBLES for d4 ROUNDS. If you touch a creature, they are petrified for the duration. (Adamant dust)

6 Mirror Walk. Shatter the fabric of space-time to teleport FAR or open a portal to a random part of the cosmos that persists for d4 ROUNDS. (A mirror containing a soul)

7 Ocular Pearl. Summon a small ball of glass. You can see auras while holding it, and can see through it remotely if it’s in the same HEX as you. (Diamond monocle)

8 Open Door. Millenia ago, before the Cataclysm, the Doors were a network of inter-cosmic portals. They probably still work fine. (Keystone of a wizard’s front door)

OTHER POSSIBLE SPELLS: Resonance, Eldritch Lenses, Reverse Time, Shatter Reality

4 ASH

1 Emberwind. Anyone caught in this cone of whirling cinders takes 2 WOUNDS, and anything flammable ignites. (Weeds from under the First Tree)

2 Blitzschreiben. Carve a rune of lightning into something. The next thing to touch it takes 2 WOUNDS and is deafened by a peal of thunder. (Lightning in a bottle)

3 Fever Dream. Touch someone to cure them of all their Addiction to a drug, or all of their WOUNDS, STRESS, or FATIGUE. They fall into a coma for 24 hours. (‘Shrooms)

4 Memento Ignius. Touch a fresh corpse and ask it a question; it must answer as truthfully as it can, though bodies know less than minds. (A 6-fingered cat’s paw)

5 Maelstrom. Control the weather for a TURN; you can make it as extreme or strange as you please. (The claws of a Wind Dragon)

6 Erode. Touch something inanimate; it crumbles, rusts, or otherwise decays. (Bone axe)

7 Creation’s Song. Spend d4 ROUNDS singing sacred, cosmically resonant tones to manifest a simple object made of one material that takes up one slot. (432Hz tuning fork)

8 Conduit. Your flesh invokes a long-forgotten primordial form; you become an Angel of Fire, Water, Wood, Metal, or Air for a TURN, taking 1 FATIGUE after. (Burned effigy)

OTHER POSSIBLE SPELLS: Summon Mephit, Deaden the Ley, Call Colossus, Homunculus

CREATING AND RESEARCHING SPELLS: SPELLS can be researched with LONG EXPENSIVE PROGRESS. At the end of that time, roll INT. If you succeed, you have made the SPELL, and whenever you roll for a SPELL, you can choose that SPELL instead. If you fail, you know how to obtain the SPELL, but it won’t be easy. It may be contained in a wand sequestered in a distant crypt or locked in the failing mind of the Archdruid in the Maze, for example. You can research the location of a TOKEN for any given SPELL with SHORT PROGRESS, though if the TOKEN is a ubiquitous object, it won’t be very fruitful.

MAKING A SPELL

• There are no generic SPELLS. Every SPELL should have some unique dimension or bit of flavor beyond the lowest common denominator. For example, there’s no Magic Missile, but instead Screaming Skull, whose whispers of madness cause STRESS.

• 2 WOUNDS, d4 ROUNDS, and a TURN are good starting points. You want each SPELL to be capable of being PUSHED, so err on the side of weak.

• Chaos is your friend. SPELLS should shake things up when used, and be found randomly, with strange effects and narrow utility. What might the spell Hold Acorn do?

• Implications are your friend. A SPELL shouldn’t go for more than 2 or 3 lines. Assume that ambiguity can be cleared up by PUSHING the SPELL to get it to do what you want.

• As a rule, summoned creatures don’t have to like you by default. They behave as they normally would, which could create more problems than it solves.
