Spellbreaker

Spellbreakers are martial specialists trained to hunt, resist, and dismantle magic-users. They possess no spellcasting of their own, but their bodies and minds are honed to sever the weave of magic. They are the bane of rogue mages, arcane tyrants, and extraplanar casters.

Class Resources

Null Focus

Max 9

Null Focus is the Spellbreaker's personal reservoir of trained, non-magical resistance. It fuels the class's Null Techniques and is spent on severing strikes, reactive parries, interdicting a caster's spell, and other anti-magic techniques. The maximum is 3 + your proficiency bonus: 5 points at levels 1-4, 6 at 5-8, 7 at 9-12, 8 at 13-16, and 9 at 17-20. Null Focus is not spell energy, cannot be counterspelled, drained, or detected by magic, and refreshes fully on a short rest.

Reset: After a short or long rest (all expended points are regained)
Spending: Spend Null Focus to activate Null Techniques. Costs range from 1 point (Severing Strike, Null Parry, Disrupting Shout, Iron Grip, Sever Enchantment, Reflexive Ward, Grounding Stance) to 2 points (Spell-Eater's Riposte, Mage-Breaker's Advance, Snare the Weave), 3 points (Arcane Interdiction, Sundering Sweep, Reflective Deflection, Severed Bond, Severing Cascade, Castigation Strike, Resonant Silence, Null Cadence), 4 points (Weave Shatter, Absolute Nullity, Mage's End), and 5 points (Final Severance, Weave Severer). You cannot spend more Null Focus than you have remaining. Iron Mind also allows spending 1 point to reroll a failed save against a spell.
Recovery: You regain all expended Null Focus when you finish a short or long rest. At 9th level, when you roll initiative and have no Null Focus remaining, you immediately regain 2 Null Focus. Improved Null Focus at 9th level also allows spending 2 Null Focus at the start of your turn to end one spell of 2nd level or lower affecting you.

Rules Text:

When you take damage from a spell, a spell attack, or a magical effect, you can use your reaction and spend 1 Null Focus to reduce that damage by your Null Die + your Wisdom modifier (minimum reduction 1).

Rules Text:

As an action, spend 1 Null Focus and study your surroundings for 10 minutes. You learn whether a creature that cast a spell of 1st level or higher within the last 24 hours passed within 1 mile of you, the direction and distance to the most recent casting site within that range, and the school of the most recent spell cast there. While tracking, you have advantage on Wisdom (Survival) checks to follow the caster's trail and on Intelligence (Investigation) checks to identify magical remnants. The range increases to 5 miles at 9th level and 20 miles at 17th level.

The target must succeed on a Wisdom saving throw against your Null save DC or be unable to cast spells that require verbal components until the end of its next turn.

Rules Text:

As an action, spend 1 Null Focus and attempt to grapple one creature within your reach. Make a Strength (Athletics) check opposed by the target's Strength (Athletics) or Dexterity (Acrobatics) check. If you succeed, the target is grappled. While grappled this way, whenever the target tries to cast a spell that requires somatic components, it must first succeed on a Constitution saving throw against your Null save DC or that spell fails and the action is wasted. While grappled this way, the target also has disadvantage on Constitution saving throws it makes to maintain concentration.

At 9th level you can end a spell of 2nd level or lower, and at 15th level a spell of 3rd level or lower.

You flick a bubble of null force over an ally as a spell comes down.

Rules Text:

When a creature you can see within 30 feet is targeted by a spell attack or forced to make a saving throw by a spell, you can use your reaction and spend 1 Null Focus. Before the attack roll or saving throw is made, that creature gains advantage on the saving throw, or the spell attack roll against it is made at disadvantage. If the spell attack misses or the saving throw succeeds, the warded creature has resistance to any damage the spell deals.

Defense None

You look at a creature and see every spell currently knotted into its body.

Rules Text:

As an action, choose one creature you can see within 30 feet. You learn whether the creature is charmed, frightened, polymorphed, possessed, or under the effect of any spell, as well as the school and level of the highest-level spell currently affecting it. You also learn whether the creature can cast spells and the highest spell level it can cast. A creature that wishes to conceal this information can make a Charisma saving throw against your Null save DC; on a success, you learn only that it is hiding something. Shapeshifters and illusions can be seen through: make a Wisdom (Insight) check against the target's Charisma (Deception) check to identify a false form.

Utility Effect

Saving Throw: Charisma

Range: 30 feet

Target: one creature within 30 feet

Rules Text:

As an action, spend 2 Null Focus and choose one creature you can see within 30 feet that can cast spells. It must succeed on a Wisdom saving throw against your Null save DC or be snared for 1 minute. While snared, the creature has disadvantage on spell attack rolls, its spell save DC is reduced by 2, and it has disadvantage on Constitution saving throws made to maintain concentration. The creature can repeat the Wisdom saving throw at the end of each of its turns, ending the effect on a success.

A wide arc of weapon and null force that strips spells from everyone in front of you.

Rules Text:

As an action, spend 3 Null Focus and sweep your weapon in a 15-foot cone. Make one melee weapon attack roll against each creature in the cone that is affected by a spell or that has spell slots. On a hit, a creature takes your weapon damage and one spell of 3rd level or lower currently affecting it ends. On a miss, nothing happens.

Duration Instantaneous

Movement None

Attack / Save The caster uses its own spell save DC or spell attack bonus against itself

Defense None

You catch a spell on your null guard and hurl it back at the hand that threw it.

Rules Text:

When you succeed on a saving throw against a spell that targets only you, or when a spell attack misses you, you can use your reaction and spend 3 Null Focus to deflect the spell back at its caster. The caster is treated as the target of its own spell: it makes a saving throw against its own spell save DC (or is hit by its own spell attack using its own spell attack bonus) and suffers the spell's effects on a failure, or half damage on a success if the spell allows a save for half damage. Concentration spells deflected this way are centered on the caster as if it had cast them on itself.

Debuff Effect

Saving Throw: the caster's own spell save DC

Target: the caster of the triggering spell

Balance Notes The Spellbreaker is a d10 martial class using the fighter and paladin chassis as a benchmark, but trades spellcasting and heavy armor for anti-magic utility. Its Null Focus pool (5 points at 1st level, 9 at 20th, fully restored on a short rest) is comparable to a monk's ki or a battle master's superiority dice and gates every one of its stronger techniques. Its damage ceiling (Extra Attack plus Castigation Strike, Mage's End, and Final Severance) sits below a fighter's sustained output but spikes higher against spellcasters, and its defensive kit (Iron Mind, Warded Reflex, Spell Resistance, Absolute Nullity) is broadly comparable to a paladin's aura against magic while remaining useless against a mundane axe. Outside combat it is a tracker and a lie-detector rather than a face or a caster, so it never steps on the rogue, bard, or wizard's toes. It has no spell slots, no concentration-based buffs for allies, and no healing, which keeps it firmly in the martial tier.

Class Features

Null Focus (Level 1)

You learn to gather and expend a reservoir of personal, non-magical resistance called Null Focus. You have a maximum number of Null Focus points equal to 3 + your proficiency bonus (5 at levels 1-4, 6 at 5-8, 7 at 9-12, 8 at 13-16, 9 at 17-20). You regain all expended Null Focus when you finish a short or long rest. Some of your techniques use your Null Die, which is a d6 at 1st level, a d8 at 5th, a d10 at 9th, a d12 at 13th, and at 17th level you roll two Null Dice and use the higher result. Your Null save DC equals 8 + your proficiency bonus + your Wisdom modifier. The Null save DC applies to every Spellbreaker technique, discipline feature, and class feature that forces a saving throw. Additionally, you know three Null Techniques of your choice from the Spellbreaker technique list, and you learn one additional Null Technique at 5th, 9th, 13th, and 17th level. Whenever you gain a level in this class you can replace one Null Technique you know with another one for which you qualify.

Mage-Scent (Level 1)

You can taste and smell magic the way a hound scents blood. You have advantage on Wisdom (Survival) and Intelligence (Investigation) checks made to notice the presence of magic, to identify a creature as a spellcaster, or to locate a place where a spell was cast within the past 24 hours. You automatically sense when a creature you can see within 30 feet of you can cast spells of 1st level or higher, and when a creature within 30 feet of you is currently under the effect of a spell (though not the spell's identity). This sense is not magical; it is a trained physical response to the pressure and residue of the weave.

Sense the Weave (Level 1)

As an action, you can open your senses to the weave and read the threads of magic around you. Until the end of your next turn, you learn the number, spell level, and school of every active spell effect within 60 feet of you, and which creature or object each effect is attached to. You also learn the highest-level spell slot any creature you can see within 60 feet possesses. You have advantage on saving throws against illusions. You can use this sense a number of times equal to your Wisdom modifier (minimum 1) per long rest.

Iron Mind (Level 2)

Your mind is a walled fortress. You have advantage on saving throws against spells and magical effects. Once per turn, when you fail a saving throw against a spell or magical effect, you can spend 1 Null Focus to reroll the save and must use the new roll. At 9th level you also add a +1 bonus to saving throws against spells; this bonus increases to +2 at 17th level.

Spellbreaker Discipline (Level 3)

At 3rd level you choose a discipline: Order of the Severed Weave, Iron Inquisitor, or Quiet Ward. Your discipline grants features at 3rd, 7th, 11th, 15th, and 18th level. These features are non-magical techniques and disciplines, never spells, and cannot be dispelled, counterspelled, or detected by magic.

Dispelling Strikes (Level 3)

Once per turn when you hit a creature with a weapon attack, you can attempt to tear a spell off it at no cost. If the creature is affected by a spell of 1st level or lower, that spell ends. If the creature is affected by a spell of 2nd level or higher, you can instead make a dispelling check: d20 + your proficiency bonus + your Constitution modifier against DC 10 + the spell's level. On a success, the spell ends. At 9th level the free automatic severing limit becomes 2nd level or lower; at 17th level it becomes 3rd level or lower. This feature never fails against your own class features, since they are not spells.

Extra Attack (Level 5)

You can attack twice, instead of once, whenever you take the Attack action on your turn.

Warded Reflex (Level 5)

When a spell or magical effect damages you or forces you to make a saving throw, you can use your reaction to brace against the weave. Reduce the damage dealt to you by your Null Die + your Wisdom modifier (minimum reduction of 1), or add your Null Die to the saving throw you are about to make. You can use this feature a number of times equal to your proficiency bonus per long rest, and you regain one expended use when you finish a short rest.

Unbroken Will (Level 7)

You are immune to the charmed and frightened conditions when they are caused by a spell or magical effect. Your thoughts, emotions, and memories cannot be read by magic, and magic cannot detect your location unless you allow it. If a spell or effect would force you to act against your will, you are unaffected by that compulsion.

Improved Null Focus (Level 9)

Your command of null force deepens. Your Null Die becomes a d10 (a d12 at 13th level, and at 17th level you roll two Null Dice and use the higher result). In addition, when you roll initiative and have no Null Focus remaining, you immediately regain 2 Null Focus. You can also spend 2 Null Focus at the start of your turn to end one spell of 2nd level or lower currently affecting you.

Severed Weave Field (Level 11)

While you are conscious, you project a 10-foot-radius null field centered on yourself. Creatures of your choice inside the field have disadvantage on Constitution saving throws made to maintain concentration and on spell attack rolls. You can suppress or resume the field as a bonus action. At 17th level the radius increases to 20 feet. The field is a non-magical pressure of null force; it cannot be dispelled, and it does not prevent your allies from casting, though it hinders concentration.

Spell Resistance (Level 14)

You have resistance to damage dealt by spells. When you succeed on a saving throw against a spell that deals damage on a failed save and half damage on a successful one, you instead take no damage.

Null Cascade (Level 18)

When you use your Warded Reflex feature, your Null Parry technique, or succeed on a saving throw against a spell cast by a creature within your reach, you can immediately make one weapon attack against that caster as part of the same reaction. If the attack hits, the caster must succeed on a Constitution saving throw against your Null save DC or the spell it was casting fails and its action is wasted.

Weave Severer (Level 20)

Once per long rest, as an action, you can spend 5 Null Focus to become a living tear in the weave for 1 minute. While transformed in this way: you have advantage on all saving throws; spell attacks against you are made with disadvantage; every spell of 5th level or lower whose effect includes an area within 30 feet of you is suppressed while you remain in the area; and once per turn, when you hit a creature with a weapon attack, every spell effect currently on that creature ends. You cannot cast spells during this time (you have no spellcasting to lose), and you take on a visible shimmer of warped, colorless air.

Resource Cost: 5 Null Focus, once per long rest
