Carian Retaliation (v1.1)

with your weapon, slash it sideways and cause a spherical barrier of blue glintstone energy, protecting you from harm from a single attack by adding +5 to your armor class against that single attack, and if it succeeds it summons 3 glintstone swords that float above your head, if an enemy goes to attack you again you can either release any number of these that you choose of which you have available. you can either choose to attack or defend with these swords.

when you use them to attack or defend you can fire any number of swords from 1 to 3 based on how many you have left. They automatically disappear after 3 turns.

Attack: each deals 1d8 force damage and if the enemy fails a strength save of DC 8+spellcasting modifier+proficiency bonus they are staggered and have a -2 to all rolls until the start of your next turn 

Defend: you can choose to fire the blade(s) at an opponent's strike during that turn as a free action during the turn in which you cast the spell, but on subsequent turns it takes a reaction. it can be a spell, weapon attack, or unarmed attack. you take the damage of the sword(s) and remove that number from their attack roll. if you fire all 3 at an attack and they all roll their highest it can remove up to 24 from their attack roll at base level.

 at higher levels: when you upcast this spell every 2 levels it adds +1 armor class and +1 summoned sword to the bunch. (It can be upcast at any level, but only gains additional strength at 3rd, 5th, 7th, and 9th level.)

1st level: 3 summoned swords, +5 to armor class

3rd level: 4 summoned swords, +6 to armor class

5th level: 5 summoned swords, +7 to armor class

7th level: 6 summoned swords, +8 to armor class 

9th level: 7 summoned swords, +9 to armor class
