Martial Archetype
Comments from the Tweeter: One of my favorite games is Guild Wars 2 and this subclass is inspired by the new warrior elite specialization by the same name. The Spellbreakers’ Meditation skills seemed like a perfect fit for Ki and I think this is a suitable antimage without being so focused on the antimage theme that you are only effective against magic users.
Spellbreaker
The spellbreaker wields their focus as both a weapon and shield, which they use to strike at the very fabric of magic, stripping it from their foes. They meditate to see past their enemies’ defenses, and they use their supernatural abilities to counter attacks.
Focus
Starting at 3rd level, your mystical training grants you access to a number of special maneuvers and a reserve of mystical energy known as focus. You have a number of focus points equal to half your fighter level, rounded up, which you can spend to fuel your abilities. You regain expended focus points when you take a short or long rest.
You begin with three maneuvers: Disrupting Strike, Featherfoot Grace, and Full Counter.
Saving Throws. Some of your maneuvers require your target to make a saving throw to resist the maneuver’s effects. The saving throw DC is calculated as follows:
Disrupting Strike. As a bonus action when you hit a creature with the ability to cast spells with a weapon attack, you can spend one focus point to muddle their internal magic. If the creature is concentrating on a spell, it has disadvantage on the saving throw it makes to maintain its concentration. Additionally, until the end of the creature’s next turn, it makes spell attacks with disadvantage, and other creatures have advantage on saving throws against its spells.
Featherfoot Grace. As a bonus action when you move, you can spend 1 focus point to increase your movement speed by 15 feet until the end of you turn and gain resistance to all damage until you stop moving.
Full Counter. As a reaction when a creature you can see within 30 feet of you makes an attack against you, you can spend 1 focus point to counterattack with a blast of energy. When you do so, each creature of your choice within 5 feet of you must make a Dexterity saving throw, taking force damage equal to 1d8 + you Wisdom modifier on a failed save. If the attacker fails their save against this ability, your AC increases by 2 against the triggering attack.
Aura Slicer
At 7th level, you can channel your focus to tear through magic. When you hit a creature with a weapon attack you can spend 1 focus point to cast the spell dispel magic targeting the creature, without expending a spell slot or spell components.
Sight Beyond Sight
At 10th level, you can sense the magic of all living things, and see things as they truly are. As a bonus action, you can spend 3 focus points to grant yourself truesight for up to 1 minute with a range of 30 feet. Once you use this ability, you can’t do so again until you finish a short or long rest.
Spellbreaker’s Soul
Beginning at 15th level, your mastery of arcane combat grants you proficiency in Wisdom saving throws. Additionally, if you fail a saving throw against a spell that allows you to repeat your save at the beginning or end of your turn to end the effect on yourself early, you can spend 2 focus points when you repeat your save to automatically succeed on the saving throw.
Winds of Disenchantment
At 18th level, you can siphon magic from the world around you. By spending 5 focus points you can cast the spell antimagic field once, without expending a spell slot. Once you use this ability, you can’t do so again until you finish a long rest.
