In my 5E Catamaran campaign there are only twenty-five wizards in the world at one time; each time one is killed their "mage spark" goes to a mortal of suitable intelligence and knowledge (the specifics of this have been left purposefully vague), allowing that mortal to become a wizard. It is possible for a wizard to use so much of their power that they weaken their spark or force it to leave entirely, or for others to forcefully harvest a mage spark from a wizard given the right knowledge and willingness to commit acts of terrible torture. So of course one of the bad guy groups in the campaign, the Stormfeather order, is going around harvesting all the mage sparks it can and cramming them into the order's leader. Those who survive this removal process become what is called an unraveler; the void left by the mage spark allows them to actively consume and destroy magic, and the Stormfeather order brainwashes those poor unfortunates who survive the harvesting process into anti-magic footsoldiers that are really effective against spellcasters. These unravelers started out as a monster type, but a player got his mage spark weakened by being part of a ritual to cast a really high level spell, so I gave him the option to become an unraveler as it made a lot of sense for his character (he is a wizard who hates the Stormfeather order for killing his family). That led to me writing up unraveler as a base class unto itself, presented below.
This class would only work in campaigns where the players run into enough spellcasters to feel useful. The weird decision for obviously supernatural monster abilities to not be "magic" makes unravelers pretty focused on actual spellcasters, but I think it could work out. It certainly is not as universally useful a base class as fighter or rogue, but I think in the right campaign it could be a lot of fun.
Unraveler Dedication
At 1st level you select your unraveler dedication, which determines what type of magic user you specialize in hunting. This is usually determined by what led you to becoming an unraveler; was your family killed by wizards, or did the cleric of a dark god wrong you in the past? Your chosen dedication grants you features at 1st, 7th, 13th, and 17th level.
Unraveling
At 1st level, you learn how to harness your interior magical void, using it to aid you against magical effects. You can activate various abilities gained from this class, each of which adds unraveler points to your character. At 1st level,unraveler points can be spent in the following ways:
As a bonus action, gain one unraveler point to give yourself temporary hit points equal to your spellcasting ability score bonus. You can gain a number of unraveler points equal to your proficiency bonus in a single bonus action. These temporary hit points are lost when you take a short rest.
As a bonus action, gain one unraveler point and treat one weapon you wield as magic until the beginning of your next turn.
As a bonus action, gain one unraveler point and give yourself advantage on a saving throw against a spell or magical effect already active on you, such as hold person. If you are under a spell that has inflicted the stunned condition on you, you may use this option despite the fact you are stunned, but it is your only action for your turn.
As a reaction when making a saving throw against a spell or magical effect, you can gain one unraveler point to give yourself advantage on the saving throw.
You lose these unraveler points in the following ways:
When you are hit with spells you lose one unraveler point per spell level, but you can never have fewer than 0 unraveler points.
As a bonus action you can either consume a use or charge of a magic item or render a magic item inert until your next long rest to reduce your unraveler points by 1d6. You must be attuned to the item.
If your unraveler points are greater than your spellcasting ability score at beginning of your turn, you suffer 1d6 necrotic damage that ignores resistances, immunities, and temporary hit points. If your unraveler points are greater than the sum of your spellcasting ability score and your proficiency bonus at the beginning of your turn, you suffer 2d6 necrotic damage that ignores resistances, immunities, and temporary hit points. If your unraveler points are greater than the sum of your spellcasting ability score, your proficiency bonus, and your level, you suffer one level of exhaustion.
If you take a short or long rest, your unraveler points are reduced to 0.
Absorb Spell
At 1st level you gain the ability to try to absorb spells that hit adjacent allies as a reaction. Doing so gives the target advantage on their saving throw, and if they save successfully you lose unraveler points as if you had been hit by the spell.
Beginning at 9th level, when you successfully save against a spell that has multiple targets, you may use your reaction to give all targets within 5’ advantage on their saving throws against that spell. Beginning at 18th level, this expands to 10’.
Unravelling Spellcasting
Beginning at 2nd level, you have learned to harness your unravelling powers to effectively cast spells, mimicking common magical effects used by other spellcasters through destroying magical energy.
Cantrips
At 2nd level, you know two cantrips of your choice from the unraveler spell list. You learn additional unraveler cantrips of your choice at higher levels, as shown in the Cantrips Known column of the Unraveler table.
Spell Slots
The Unraveler table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these unraveler spells, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest. For example, if you know the 1st-level spell shield and have a 1st-level and a 2nd-level spell slot available, you can cast shield using either slot.
Spells Known of 1st Level and Higher
You know two 1st-level spells of your choice from the unraveler spell list. The Spells Known column of the Unraveler table shows when you learn more unraveler spells of your choice. Each of these spells must be of a level for which you have spell slots. For instance, when you reach 5th level in this class, you can learn one new spell of 1st or 2nd level. Additionally, when you gain a level in this class, you can choose one of the unraveler spells you know and replace it with another spell from the unraveler spell list, which also must be of a level for which you have spell slots.
Spellcasting Ability
Your spellcasting ability is determined by your dedication, as listed below. You use that ability whenever a spell refers to your spellcasting ability. In addition, you use that ability modifier when setting the saving throw DC for a unraveler spell you cast and when making an attack roll with one.
Spell save DC = 8 + your proficiency bonus + your ability modifier
Spell attack modifier = your proficiency bonus + your ability modifier
Spellcasting Focus
You can use an unravelers totem as a spellcasting focus for your unraveler spells.
Unraveler Fighting Style
At 2nd level, you adopt a style of fighting that incorporates your unraveler abilities as your specialty. Choose one of the following options.
Bolt Slinging
You gain a +2 bonus to attack rolls you make with cantrips.
Distraction
When wielding a melee weapon with two hands, you can specify one hostile creature adjacent to a you that you can see as a bonus action each round. Until the end of its next turn, that creature suffers disadvantage on all spell attack rolls and targets of its spells have advantage on their saving throws against those spells.
Interference
When you make a successful ranged weapon attack against a target maintaining concentration, the target has disadvantage on their Constitution save to maintain concentration. If the target fails its Constitution saving throw, it takes takes force damage equal to your spellcasting ability score bonus.
Spell Shield
When wielding a shield, as a reaction to an adjacent ally being hit by a spell attack roll made by an enemy you can see, you can impose a penalty on spell attack rolls against that character equal to your spellcasting ability score bonus until the beginning of your next turn. If the attack still hits, your ally has resistance to that spell’s damage.
Spellparry
Beginning at 3rd level, when you are targeted with a spell attack roll, you can spend your reaction to increase your Armor Class by your spellcasting ability score until the beginning of your next turn, but only against cantrips and spells.
Ability Score Improvement
When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.
Extra Attack
Beginning at 5th level, you can attack twice, instead of once, whenever you take the action on your turn.
Magic Sense
The presence of magic registers on your senses like the pressure of a storm about to strike. As an action, you can open your awareness to detect such forces. Until the end of your next turn, you know the location of any constructs, undead, fey, or elementals within 60 feet of you. You know the type (construct, undead, fey, or elemental) of any being whose presence you sense, but not its identity. Within the same radius, you also detect the presence of any place that has an active spell on it, such as a teleport circle, antimagic field, etc. You can use this feature a number of times equal to 1 + your spellcasting ability modifier. When you finish a long rest, you regain all expended uses.
Spell Evasion
Beginning at 6th level, you can use your unravel powers to deflect area of effect spells away from you. When you are subjected to an spell effect that allows you to make a saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.
Cannibalize Power
Beginning at 6th level, you can consume your unraveler spell slots to reduce your unraveler points by the level of the spell consumed as a bonus action.
Channel Power
Beginning at 10th level, you know a limited number of spells drawn from the spell list for the class which your dedication specializes in, so at 10th level God Killers select two spells from the cleric list. These spells cannot be higher in level than your highest unraveler spell slot. Also you can gain unraveler points to take these additional actions.
Cast a spell from your available dedication spells, following the normal rules for that spell, gaining one unraveller point per spell level.
Beginning at 15th level, gain 6 unraveler points to cast one of the following spells using the normal rules for that spell: Forbiddance, Globe of Invulnerability, True Seeing
Beginning at 17th level, gain 7 unraveler points to cast one of the following spells using the normal rules for that spell: Sequester
Beginning at 19th level, gain 8 unraveler points to cast one of the following spells using the normal rules for that spell: Anti-Magic Shell, Feeblemind, Mind Blank
Unsettling
Beginning at 11th level, your lack of innate magical spark is so striking that others find it disconcerting, if not out right frightening. People can feel there is something “wrong” about you by just looking at you. You can gain an unraveler point as a bonus action to get advantage on an Intimidation check.
Drain Spells
Beginning at 14th level, you can drain spells from those you strike in combat. When you hit an enemy who can cast spells with a melee or ranged weapon attack, you can spend a bonus action and gain an unraveler point to try and drain spells from the target. The target must make a Wisdom saving throw against your spellcasting DC; if this save fails, the victim loses one of their lowest level unexpended spell slots and you gain lose one unraveler point per spell level. If the Wisdom save is successful, no spells are lost.
Consume Magic
At 15th level you gain the ability to subsist on magical power alone. If you lose three unraveler points due to spells being cast on you, you do not need food or water for that day. If you lose six unraveler points due to spells being cast on you, you gain advantage on all Constitution saves against inclement weather, including extremes of hot and cold, until your next long rest.
Spellbreaker
At 20th level you become the incarnation of anti-magic, becoming permanently magic resistant. You have advantage on all saving throws against spells, all spell attack rolls against you have disadvantage, and you reduce your unraveler point total by one at the beginning of each of your turns.
Unraveler Dedications
Your ability to undo magic comes with a particular focus, making you more effective against a specific type of magic. This may be a result of how you gained your unraveler powers, such as gaining the dedication of a godkiller by bathing in the blood of a dead deity, or could be a product of specific training.
Beast Slayer
Beast Slayers seek to end the power of the druids, seeing these magicians of the primal world as nothing but a threat to themselves, their people, mortalkind, etc. Some Beast Slayers are from urban areas and see druids as impediments to the growth of civilization, while others are from rural areas and have more personal grudges against druids; not every druid is a kindly nature guardian and more than a few subscribe to the power of blood sacrifices.

True Form
At 13th level you gain the ability to force creatures not in their true form to revert to their true form, whether they were changed by spell, monster ability, or by a druid’s wildshape ability. As an action, you can gain three unraveler points to force a target within 60 feet not in their true form to make a Wisdom saving throw against your spellcasting DC; if they fail the saving throw they revert to their original form immediately as if the spell or ability used to change shape had ended and the target is stuck in its true form until it takes a short rest. If the target succeeds at the saving throw, it retains its altered form. If the creature is in its true form when this ability is used and it fails its save, it may not change shape until it completes a short rest.

Beginning at 19th level, as long as you have five or more unraveler points, allies within 30 feet of you are immune to magically created difficult terrain and have advantage on saving throws against poison and charm effects.
