Ferromancer

Ferromancers are born with lodestone in their blood — a vein of living magnetite that answers to will instead of weather. Where other sorcerers inherit fire or frost, theirs is the quiet, pulling hunger of iron: nails lift from doorframes when they are angry, blades swing wide of their ribs, and the small steel rings of a merchant's scale tremble when they walk past. They are not smiths and not soldiers, though smiths and soldiers court them. They are negotiators between flesh and metal, able to make a knight's sword refuse its master or turn a volley of arrows into a harmless rain of iron. Most ferromancers learn early that their gift is a courtesy, not a conquest — a magnet that grabs too hard drags the world onto itself — and the wise ones cultivate restraint the way a pyromancer cultivates distance from dry grass. They are rare, quietly feared in armories, and prized wherever steel decides who lives.

Class Resources

Charge

Max 12

Charge is the magnetic tension in your blood. It powers your signature aura emanations and your deflection reaction. At 1st level your maximum Charge equals 2. Your maximum Charge increases by 1 whenever your ferromancer level becomes even (4 at 2nd level, 6 at 8th, 8 at 14th, 10 at 18th, and 12 at 20th — see the Ferromancer table). You regain all expended Charge when you finish a Long Rest, and you regain 2 Charge when you finish a Short Rest.

Reset: After a Long Rest (fully); a Short Rest recovers 2 Charge
Spending: You can spend Charge in the following ways: (1) to activate an aura (Bonus Action; cost listed in the aura entry — most cost 1-5 Charge); (2) to use your Lodestone Blood deflection Reaction (1 Charge); (3) to use Steel Reserves healing (1 Charge); (4) to use Polemaster's Pulse on a damaging spell (1 Charge); (5) to fuel subclass abilities that list a Charge cost. You cannot spend Charge while Incapacitated, and a single effect cannot reduce your current Charge below 0. When you deflect an attack with Lodestone Blood and it misses, you regain 1 Charge (no more than once per round).
Recovery: Long Rest: regain all expended Charge. Short Rest: regain 2 Charge. Deflection success (per Steel Reserves feature, gained at 7th level): regain 1 Charge, once per round. Some subclass features may also restore Charge; when a feature restores Charge, it cannot exceed your maximum.

On a failed save, the creature is enclosed for the duration. Nothing—not physical objects, energy, or other spell effects—can pass through the barrier, in or out. A creature or object inside can't be damaged by attacks or effects originating from outside.

You can form it into a hemispherical dome or a sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-by-10-foot panels. Each panel must be contiguous with another panel. In any form, the wall is 1/4 inch thick. If the wall cuts through a creature's space, the creature is pushed to one side of the wall (you choose which side). Nothing can physically pass through the wall.

Balance Notes The ferromancer is built on the sorcerer chassis (d6 Hit Die, simple weapons, no armor, full Charisma caster, same spell known/cantrip/slot progression). Its power budget is split between spells and a small menu of magnetic-field auras, which are gated by the limited Charge resource (2 + one-half class level, rounded down; max 12 at level 20) and by Bonus Action economy, plus a Reaction-based deflection rider with a Charge cost. No martial maneuvers, transformations, or companions are granted, and the aura list deliberately avoids healing, teleportation, and outright control immunities. Deflection is limited by reactions per round, Charge per rest, and (for the capstone) once-per-Long-Rest. Auras never stack without the 18th-level Lodestone Apex feature, which is itself a late-game payoff. Overall the class trades the sorcerer's Metamagic flexibility and sorcery points for a small, thematic aura toolkit and a bounded defensive reaction.

Class Features

Spellcasting (Level 1)

You draw on the lodestone blood in your veins to cast spells. Charisma is your spellcasting ability for your ferromancer spells. You know a small number of spells from the ferromancer spell list, and you use spell slots to cast them. You can use an arcane focus (a lodestone, a magnetized rod, or an iron tuning fork) as a spellcasting focus for your ferromancer spells. You know the number of cantrips and spells shown in the Spellcasting table, and you replace one known spell or cantrip when you gain a ferromancer level (as described under the Spellcasting ability).

Lodestone Blood (Level 1)

Your veins run with living magnetite. You sense the presence of ferrous metal (iron, steel, magnetite, and similar) within 30 feet of you, as though you had blindsight for the purpose of detecting such objects only. Additionally, when a creature you can see within 10 feet of you makes an attack roll with a ferrous weapon against you or an ally, you can use your Reaction and expend 1 Charge to impose Disadvantage on that attack roll. If the attack misses, the weapon is dragged 5 feet toward you (harmlessly) and the attacker cannot make another attack with that weapon against you until its next turn.

Resource Cost: 1 Charge

Magnetic Wellspring (Level 1)

You gain the Charge resource and the ability to project magnetic field auras (see the Auras section of the Ferromancer abilities). Auras are self-centered emanations that cost Charge to activate and last for their listed duration. You know how to project Steel Ward and Pulling Field; you learn more auras by selecting them from the Auras list (see abilities.auras) when you gain levels in this class. Activating an aura requires a Bonus Action and the listed Charge cost. While at least one aura is active, the hair and clothing of creatures in the aura's radius stir, and ferrous objects within it rattle and drift toward you.

Ferrous Insight (Level 2)

As a Magic action, you can touch a nonmagical or magical ferrous object and instantly learn whether it is magical; if it is, you learn its school of magic and whether it is currently bound to a spirit, a curse, or an ongoing spell. Additionally, you add double your Proficiency Bonus to ability checks made to lift, push, or break a ferrous object.

Iron Discipline (Level 3)

At 3rd level you choose a ferromancer subclass — the Iron Choir, the Rustwarden, or the Pulling Duelist — gaining its 3rd-level features. Your choice grants features at 3rd, 6th, 10th, and 14th level.

Improved Deflection (Level 5)

Your Lodestone Blood reaction improves. It now works against ranged attacks made with ferrous ammunition (arrows, bolts, sling bullets of iron or steel, and thrown ferrous weapons) as well as melee attacks, and it can protect any ally within 30 feet of you. If a deflected ranged attack misses, you can use the same Reaction to redirect the projectile at another creature of your choice within 60 feet, using the original attack roll.

Steel Reserves (Level 7)

When you successfully deflect an attack with your Lodestone Blood reaction, you regain 1 Charge. Also, as a Bonus Action you can expend 1 Charge to regain Hit Points equal to 1d6 + your Charisma modifier; this healing is doubled if the object you are touching is a ferrous object you have held for at least 1 minute.

Resource Cost: 1 Charge (for healing)

Polemaster's Pulse (Level 11)

When you cast a spell of 1st level or higher that deals damage, you can expend 1 Charge to change all of that spell's damage to Force damage, or to add your Charisma modifier as Force damage to one target of the spell. Only one of these options can be chosen per casting.

Resource Cost: 1 Charge

Iron Cloak (Level 15)

You have Resistance to bludgeoning, piercing, and slashing damage from attacks made with nonmagical ferrous weapons. While at least one aura is active, this Resistance extends to magical ferrous weapons as well.

Lodestone Apex (Level 18)

You can maintain two auras simultaneously (activating and sustaining both normally). When you activate a second aura while one is already active, its Charge cost is reduced by 1 (minimum 1). Additionally, the radius of all your auras increases by 10 feet.

Master of Magnetism (Level 20)

You ascend as a true master of magnetism. You can cast any 1st-level or higher spell you know at its lowest level without expending a spell slot; once you do, you can't do so again until you finish a Long Rest. Additionally, once per Long Rest you can enter a state of total magnetic mastery for 1 minute: during it, you have Advantage on all attack rolls, all your aura activations and sustains cost 0 Charge, and whenever a creature makes an attack roll against you with a ferrous weapon, you can use your Reaction to redirect the attack at a creature of your choice within the attack's range (using the original roll).

Resource Cost: 1/Long Rest (each effect)
