Rather than using typical instruments to augment their spells, Screamweavers are bards that primarily use the screams of their enemies to weave spells into existence.

Battle Proficiencies

You gain proficiency with Martial weapons, Medium armor and shields.

Scream Weaving

You gain the ability to weave your opponent's screams to cast spells. Once on each of your turns after successfully hitting a creature with a melee weapon attack, you can use a bonus action to cast a cantrip with a casting time of 1 action or shorter. This spell is cast using your spellcasting modifier and spell save DC, but is cast from your opponent. This means the range starts from their location and cantrips that target self such as Blade Ward will be cast on the creature. The creature must be capable of screaming to use this trait on them.

Extra Attack

You can attack twice instead of once whenever you take the Attack action on your turn. Alternatively, if you successfully damage a creature with a melee weapon attack using your first attack, you can choose to cast a spell with a casting time of 1 action or shorter instead of attacking an additional time. This spell similarly to the Screamweaving trait, meaning the spell is cast from the enemy, meaning that the range starts from their location and spells that target self will be cast on them. If you cast a spell using this trait, you cannot use the Screamweaving trait on that same turn.

Inspiring Screams

You gain a sadistic inspiration from hearing your opponents scream. Whenever you see or hear a creature hostile to you scream  roll a d4. On a 4, regain one of your Bardic Inspiration Dice.
