Weavesplinter

Starting at 3rd level, you learn how to focus your physical prowess to strike at magic around you. Once per turn whenever you hit a creature with a melee weapon, you can choose to deal no damage and instead disrupt a magical effect on the target. You can dispel a magical effect in your reach if it is a leveled spell up to a third of your fighter level or a magical effect from a creature with a CR up to your fighter level. Additionally, if you are targeted by a spell or magical effect or are caught in the area of a spell or magical effect, you may use your reaction to disrupt the spell or magical effect.

You can use this feature an amount of times equal to your proficiency bonus. You regain half of your uses on a short rest and all of your uses on a long rest.

Reality Strike

Starting at 7th level, you learn to divert the magic you quell rather than entirely extinguish it. Whenever you successfully Weavesplinter a spell or magical effect, you can make a Reality Strike on your next turn in the place of a melee weapon attack as part of the Attack action. When you do, you make a melee weapon attack with a reach of 60 feet, dealing your normal weapon damage as well as a number of d4s equal to the spell's level or a third the CR of the creature that created the effect.

Thaumaturgical Resistance

Starting at 10th level, your training in combating magical threats grants you a level of resistance to them. You have advantage on saving throws against magical effects.

Material Anchor

Starting at 15th level, whenever you attempt to Weavesplinter a spell or magical effect and fail to completely disrupt it, you still manage to unravel the edges of the magic. If the level of the spell or the CR of the creature creating a magical effect is higher than your ability to disrupt, you make a check with a bonus equal to a third your fighter level against a DC of 10 + the level of spell / half the CR of the creature, partially disrupting it on a success. If the spell or effect forces the target(s) to make a saving throw, they do so with advantage. If the spell or effect requires an attack roll against the target(s), it is made with disadvantage.

Stability Projection

Starting at 18th level, your mastery of the Weavesplinter and capacity to remove unwanted magical influences are unrivaled. Your reach when making a Weavesplinter attack is 30 feet.
