Cosmic Knight

Thousands of years ago sorcerous power was plentiful. Warriors learned to incorporate and bend that power to their will. These warriors known as Cosmic Knights formed the blades and staves of their weapons from pure cosmic power. Cosmic Knights were peerless in battle. As years went by their society crumbled and sorcerous power waned. Fewer Cosmic Knights were trained as the years wore on. You have picked up their legacy. You have learned a fraction of the powers that made Cosmic Knights so peerless.

Cosmic Warrior

You have been trained in the art of war. You are now proficient with Martial weapons. You are proficient with light and medium armor as well as shields.

Cosmic Blade

When you learn this tradition at 2nd level you gain the ability to forge a blade of Cosmic energy. You are considered proficient with this weapon. You must spend a week forging the weapon from the hilt of a martial weapon. This weapon has the versatile property. This weapon is magical for the purpose of overcoming damage reduction.

While grasping the hilt, you can use a bonus action to cause a weapon of pure astral energy to spring into existence or to make the weapon disappear. You may use this weapon to make a Melee Spell Attack with this blade, doing 1d8 force damage on hit or 1d0 if held in 2hands. You add your Intelligence to the attack and damage of your melee weapon attacks instead of Strength or Dexterity.

Fade Shield

At 2nd level, you have learned the ability to convert arcane energy into pure cosmic power. By sacrificing a spell slot you receive temporary hit points. By consuming a spell slot up to fifth level you gain temporary Hitpoints equal to 1d8 + 1d8 per spell level sacrificed. The first Spell slot consumed in this manner is maximized based on your highest spell level that you are able to cast (maximum 48 HP). This feature is not compatible with Pact Magic.

Cosmic Attack

At 6th Level, your ability to harness Cosmic power hastens your attacks. You can attack twice, instead of once, whenever you take the Attack action on your turn.

Cosmic Fury

At level 10 you've learned how to redirect the cosmic flow of an individual to do them harm. When you do damage with your Cosmic Blade or a spell you cast you may choose to lose your temporary HP to do additional damage to a single creature you're rolling damage against equal to half your lost temporary hit points (rounded down)

Cosmic Cloak

At level 14 you've learned to enter the ethereal plane during battle. When you're hit by an attack you may use your reaction to enter the ethereal plane thereby becoming completely invulnerable to damage until the start of your next turn. You are also unable to influence the Material Plane until you return to it. You cannot use this ability again until you finish a long rest.
