Style Meter

You gain a style meter when you enter combat ranging from D to S. You start combat at D rank and each successful attack that's different from the last attack (no matter if the last attack hit or not) bumps your rank up to the next stage. You can choose to use one of the moves available at each rank if you meet the requirements for it. You must keep attacking with different moves, for each turn that you go without successfully landing an attack you will go down a style rank. You can only use one Style Action of the same rank per turn. After using an S Rank move you are demoted to B Rank. Saves for these attacks are DC 8 + STR + Proficiency Bonus.

D Rank
Glimmer - As a bonus action, your next attack will deal extra 1d4 fire damage and gain an additional 5 ft. of reach. For ranged weapons the range is increased by 30 ft.
Starglide - As a reaction you may attempt to move 5 ft into any direction after being targeted by an attack, gaining a +1 to AC against that attack.
Pulsewave - As a bonus action, you can make it so that your next attack deals damage in a 5ft. cone in front of you instead.

C Rank
Starlunge - As an attack, lunge forward 10 ft. and impale an enemy as you send out shimmering lights. If the attack is successful, a mini supernova explodes from the location with beautiful lights, dealing 2d6 fire damage to every enemy within 5 ft. of the target (including the target) on a failed CON save. Nothing happens on a successful save. If this is used after using Glimmer, the damage is increased to 3d6.
Radiant Kick - As an attack, blink to an enemy that is within 30 foot of you that is not behind total cover, kicking them with an explosion of brilliant lights. This attack deals extra 2d4 + STR mod fire damage and knocks the target 10 foot in any direction on a failed STR save. On a successful save, the target is not pushed. If this is used after using Starglide, the blink range is increased to 45 ft.
Spinning Lights - As an attack, lunge forwards 10 ft. while spinning, dealing rapid slashes to all enemies you get within 5 foot of, making 2 attacks to each, both dealing 1d4 + STR mod fire damage. If this is used after using Pulsewave, you can move an extra 5 foot.

B Rank
Radiant Impale - As an attack, impale an enemy and surge their body with the power of stars. You first impale the target and rise their body into the air surging their body with the power of stars. On a failed STR save, the target takes 3d8 radiant damage and falls prone. On a successful save the damage is halved and the target does not fall prone. If this is used after starlunge, the target must use all of their movement to get up instead.
Starblitz - As an attack, unleash rapid slashes on an enemy that spark with colorful lights. On a failed DEX save, the target takes 6d4 radiant damage. If this is used after Radiant Kick, the DC is increased by 1.
Sweeping Lights - As an attack, spin around and breakdance as you shoot blinding starlight out of your limbs. All enemies in a 15 ft. circle must make a DEX save or take 2d6 radiant damage and have their movement speed halved until the end of your next turn. If this is used after Spinning Lights, this deals 3d6 damage instead.

A Rank
Starfall - As an attack, flip a star coin up into the sky, shooting it with a glimmering blast right afterwards targeting an enemy of your choice. This attack has an additional +2 to hit and deals 4d8 radiant damage. If this is used after Radiant Impale, the additional to-hit bonus is +4 instead.
Light Cleave - As an attack, send out a shining slash in a 120 ft. straight line. All creatures caught must make a Dex save or take 6d4 radiant damage and become blinded until the end of your next turn. On a successful save damage is halved and creature is not blinded. If this is used after Starblitz, you can teleport to a creature hit by this attack and use a normal melee attack as a reaction.
Blast Shower - As an action, summon many falling stars in a 15 ft. radius around you. All targeted creatures inside must make a Dex save or take 2d6 radiant damage. If the enemies' CR are lower than your fighter level and are under half hp, you can instantly execute them. If this is used after Sweeping Lights, the range is increased to 20 ft.

S Rank
Only 1 S Rank buff can be active at a time.
Showstopper - As an action, imbue your weapons with radiant energy. Gain increased 5 ft. melee / 15 ft. ranged range, additional 2d6 radiant damage on your attacks and all of your attacks deal radiant damage instead. If this is used after Starfall, your next attack deals additional 2d6 radiant damage.
Coreheart - As an action, imbue your heart and body with radiant energy. Your move speed is doubled, gain an additional attack (can not be used for Style Actions), and gain a +2 to AC. If this is used after Light Cleave, your next disengage is a bonus action and teleports you anywhere within your movement speed radius.
Starkiller: End - As an action, sheathe your sword and pose as many slashes and explosions occur. All targeted creatures within a 30 ft. radius must make a DC + 4 (Cannot go over 20) save or take 5 + Fighter Level d4 radiant damage. If this is used after Blast Shower, you can use cutting words on creatures that failed the save once.
