Magic & Spellcasting¶

"Anyone can wave a stick and shout. The trick is the will to hold the shape steady while the world tells you no. Spend your mana like a purse, not a flood - and learn what your fire does to a man made of ice before you waste it." - Marcellus, Arcane Collegium

Magic in Ghelmyon is not a separate game laid over the swordfighting. A spell is just another way of taking an action - it rolls against the target the same way a blade does, it costs you a resource, and it can miss. This article is the how does casting actually work reference: your mana pool, how a cast resolves, what the schools and elements do, and which classes get to throw spells at all.

For the per-class spell lists, see the class pages - Mage, Cleric, Paladin, Necromancer. For healing magic in the wider context of injury, see Wounds & Healing.

Mana - the spellcaster's purse¶

Every cast spends mana. Your mana pool isn't rolled separately - it's derived from your mind and spirit: a strong Willpower with some Spirit behind it gives you a deeper pool. A pure muscle build has little or no mana; a dedicated caster has plenty.

If you have no magical training at all, you have no mana pool - the /mana screen will tell you so plainly. Learning a magic skill is what opens the pool up.

Mana comes back on its own. Each turn that passes, a little mana trickles back, again scaling off Willpower and Spirit - so the same stats that give you a big pool also refill it faster. You don't have to do anything; just keep playing and it refills between fights.

When you want it back faster:

meditate - sit and focus. Your next stretch of regeneration comes in at double rate. Cheap, costs only time, and the go-to between encounters.
Mana potions - instant top-up in a pinch. Mages and Necromancers start with a few; buy more from alchemists. Carry some if you plan to cast through a long fight.
Rest and sleep - a proper rest refills the pool along with your HP.

Check your pool any time with /mana (the bar + regen rate) or /spells (your known spells, each flagged castable or not against your current mana).

Casting also draws a little fatigue - magic is tiring work, not free. Spellcasting all day without rest wears you down the same way marching does.

How a cast resolves - the roll¶

This is the heart of it. When you cast at an enemy, the engine doesn't just apply the spell - it rolls for it, exactly like a weapon attack.

Ghelmyon uses a roll-over d100: a hundred-sided die, and you want to roll at or above a threshold. The better your casting, the lower that threshold drops - so a skilled caster needs a smaller number and lands far more often.

Two things move the threshold in your favour:

Your spell power - driven by your casting stat. For most arcane work that's Intelligence; clerics and paladins channel Faith; necromancers draw on Spirit; bards lean on Charisma. Spirit and Willpower lend a hand across the board.
Your school rank - the more practised you are in that school (Arcane Arts, Faith Magic, Necromancy, and so on), the sharper every spell in it lands.

And one thing moves it against you:

The target's spell defence - their Willpower and Spirit resist your magic, and some creatures carry outright magic resistance that both lowers your odds and softens the hit. (A few spells carry armour penetration to chew through that resistance.)

Roll over the threshold and the spell lands. Roll under and it fizzles - the mana is still spent, but nothing happens. Bigger margins of success hit harder, and a high Intelligence (or your spell's stat) adds a flat bump on top.

Buffs and heals don't roll to hit - casting a shield on yourself or a heal on an ally just works. It's attack and hard crowd-control spells that have to beat the target's defence.

For the wider combat picture this slots into - turn order, stances, aiming - see Combat 101.

The five kinds of spell¶

Every spell is one of five types, and the type decides how it behaves:

Attack - rolls to hit, deals damage. May also carry an element, a damage-over-time burn, a status effect, or life drain (heals you for a slice of the damage dealt - the necromancer's bread and butter).
Buff - strengthens you or an ally: armour, a stat boost, regeneration, a holy ward. Always lands. Lasts a few turns.
Debuff - weakens or controls an enemy: freeze, entangle, fear, silence, sleep. The hard control checks the target's Willpower to see if it sticks.
Heal - restores HP to you or an ally. No roll; it simply mends. This is the layer Clerics and Paladins are built around - see Wounds & Healing.
Utility - everything else: a conjured Light, Detect Magic, a Smoke Bomb to guarantee an escape, scrying a distant place, reading an enemy's stats with Insight, or Mana Tap to pull a little mana back from the air.

Elements - fire, frost, and what they're good against¶

Many attack spells carry an element, and the element is not just flavour - it interacts with what you're hitting:

Element	Tends to be strong against	Tends to be resisted by
Fire	Plants and the cold-blooded	Things already at home in flame
Frost	The unprotected	Undead and the frost-born
Lightning	Things in water	The well-grounded
Dark	The living	The undead (who shrug it off)
Nature	The undead and the unnatural	Constructs

A spell that hits a weakness lands noticeably harder; one that hits a resistance is blunted; and a few foes are flat immune to a given element, where the spell does nothing at all. The lesson Marcellus gives above is real: know what you're throwing fire at. Carrying two elements covers far more of the bestiary than mastering one.

Elements also do a few extra tricks. Fire spells often leave a target burning for a few turns; frost can leave them chilled (slower) or outright frozen; and the right spell can shatter a frozen foe for a brutal bonus. Outdoors, the weather even leans on your element - a storm sharpens lightning, and so on.

Spell combos. Cast certain spells back-to-back and they chain: follow an Ignite with a Fire Bolt for a Searing Strike, or a Frost Bolt into a Fire Bolt for a Steam Burst. The /combos screen lists the pairings you can pull off. The game tells you by name when a combo fires.

Spell schools¶

Spells are grouped into schools, and your rank in a school sharpens every spell in it. The main combat schools:

Arcane (Arcane Arts) - raw force: bolts, blasts, shields, dispelling. The Mage's home ground.
Faith (Faith Magic) - divine power: Lay on Hands, Bless, Smite, holy wards, and at the heights, resurrection. Clerics and Paladins both draw from it.
Necromancy - life-drain, fear, raising the fallen as servants, withering decay. The Necromancer's craft.
Nature - restorative growth, thorned shields, entangling vines.
Divination - sight and foresight: scrying, insight, prophecy, and a steadying of the mind.

Beyond those, Performance (bardic war-cries and lullabies), Transmutation (stoneskin, sharpened blades, earth-shaking power) and Engineering (a tinkerer's flashbangs and turrets - willpower and wit rather than mana) round out the casting classes' kits.

Within a school, spells form a ladder: the basics are castable from your first day, while the heavy hitters are rank-gated - you must earn enough rank in the parent school before the spell will fire. Try to cast above your rank and the game tells you so rather than letting you waste the mana. Climbing the ladder is how a fresh caster grows into the showstoppers. See Skills & Training for how that ranking works.

Who can cast?¶

Magic isn't class-locked to one archetype - several classes touch it, to very different depths:

The dedicated casters (a deep pool, a full school from day one):

Mage - the pure arcanist. Starts strong in Arcane Arts, and a Mage's spells can land critical hits that the other casters' don't.
Cleric - the party's divine healer. Channels Faith Magic efficiently, and heals harder than anyone.
Paladin - the holy warrior. Also draws on Faith Magic, headlined by Lay on Hands, woven into a martial kit.
Necromancer - the dark caster. Necromancy built around draining life and commanding the dead.

The partial casters (a small, focused toolkit alongside their real job):

Scholar - leans on study and a few utility spells more than raw blasting.
Bard - bardic Performance: rallying war-cries, sleep-inducing lullabies, songs that mend the party.
Wanderer, Herbalist, Tinkerer, Monk - each gets a modest self-sustain or trick. The Monk's "magic" costs no mana at all - it's pure willpower and disciplined breath.

There are also mage factions - orders like the Arcane Collegium, the River Seers, the Wild Coven and others - that teach their own exclusive spells once you've earned standing with them. Fall to hostile with a faction and you can no longer cast what they taught you. Earning your way into an order is one of the main ways to widen a caster's repertoire beyond the class basics.

When a cast won't fire¶

The game stops you cleanly - and tells you why - rather than fizzling silently. The common reasons:

Not enough mana - it names the spell and how much short you are. meditate, sip a potion, or pick a cheaper spell.
Rank too low - the spell is above your school rank. Train up first.
No target - an attack spell with nothing hostile in the room.
Faction severed - the spell was taught by an order you've turned hostile to.
Noob / training mode - attack spells only work on training dummies while you're learning the ropes. Head to an arena, or turn the mode off, to cast at real foes.

A genuine fizzle is different from all of those: the cast fired, the mana was spent, but your roll came up short of the target's defence. That's not a bug - that's the dice. Build up your casting stat and your school rank and it happens far less.
