Blade of the Storm

Wizards who follow the Blade of the Storm tradition are masters of speed, precision, and overwhelming force. Blending the ancient arts of the Bladesingers with the unwavering discipline of the samurai, they move across the battlefield with terrifying purpose, each strike measured and devastating.

Their magic flows like a storm contained within a blade — controlled, focused, and ready to be unleashed in a flash of lightning and a crash of thunder. To a Blade of the Storm, battle is an expression of pure will: swift, absolute, and merciless.

Through years of relentless training, they achieve a state of perfect equilibrium between sword and spell. In the blink of an eye, they cut down foes, their arcane power crackling along their blade in storms of lightning and bursts of raw thunder. They do not fight with rage or chaos; they fight with clarity, their every movement guided by flawless precision.

Those who witness a Blade of the Storm in battle often see nothing more than a sudden flash of steel, a surge of wind, and the collapse of their enemies.

Storm Blade

Your mastery of blade and storm begins to awaken.

• You gain proficiency with martial melee weapons and medium armor.

• When wielding a one-handed melee weapon without a shield, you can add your Intelligence modifier to your attack and damage rolls with that weapon.

• Whenever you hit a creature with a melee weapon attack, you can deal additional lightning or thunder damage equal to your proficiency bonus. You choose lightning or thunder when you hit.

 

Flash Step

Your movement becomes as swift and inevitable as a thunderclap.

• As a bonus action, you can teleport up to 10 feet to an unoccupied space you can see.

• Immediately after teleporting, your next melee weapon attack before the end of your turn has advantage.

You can use this feature a number of times equal to your Intelligence modifier (minimum once). You regain all expended uses when you finish a long rest.

You gain a cantrip, called Yamato, that is unique to your subclass.

Tempest Strikes

Your mastery of swordplay and magic deepens into a deadly rhythm.

• Extra Attack: You can attack twice, instead of once, whenever you take the Attack action on your turn. Moreover, you can cast one of your cantrips in place of one of those attacks.

• Additionally, whenever you hit a creature with a melee weapon attack, you can mark them with arcane energy until the start of your next turn.
  The next time you deal lightning or thunder damage to a marked creature, you deal bonus damage equal to your proficiency bonus.

Arcane Sheath

You master the technique of storing magic within your strikes.

• When you cast a spell of 1st level or higher, you can sheathe it into your weapon instead of casting it immediately.

• As part of a melee attack within 1 minute, you can release the spell through your weapon, targeting the creature you hit.
  The spell must target only that creature and have a casting time of 1 action.

• Casting the spell this way requires no verbal or somatic components and can't be counterspelled.

You can use Arcane Sheath once per short or long rest, or by expending a spell slot of 2nd level or higher.

Storm Unbound

 

• Extra Attack (2): You can now attack three times, instead of twice, whenever you take the Attack action on your turn.

• When you cast a spell that deals lightning or thunder damage, add your Intelligence modifier to one damage roll of that spell.

• Whenever you teleport (such as with Flash Step or a spell), each creature within 5 feet of both your starting and ending space takes lightning or thunder damage equal to your wizard level.

• Once per turn when you hit a creature with a melee weapon attack, you can force it to make a Constitution saving throw (DC = 8 + your proficiency bonus + your Intelligence modifier). On a failure, it is stunned until the end of your next turn.
  You can use this stun a number of times per long rest equal to your proficiency bonus.
