Conjure Aspect

You call on your patron and conjure an aspect of them to fight alongside you. 

Upon casting the spell a medium sized creature, whose appearance changes based on your patron, materializes in a space within 5 ft of you. This creature has the following attributes:

The creature's HP is equal to your charisma modifier times your Warlock level. The creature has a base speed of 30 ft. You may choose if this is a walking speed, swimming speed, or flying speed. The creature's speed for the unchosen movement types is 15 ft. The creature has the Attack action, which deals 3d6 psychic damage and uses your spell attack modifier to hit. The creature may also take the Help action. The creature also has 1 2nd level spell slot, and has access to the spells Misty Step and Shield. The creature uses your spell attack modifier and spell save DC. 

While the creature is manifested, your pact weapon is treated as a standard +1 magic variant of its non-magical variety.
