Uttering an incantation, you draw on the magic of the Outer Planes manifesting the incomprehensible power of a Great Old One to transform yourself. You gain the following benefits until the spell ends:

• You are immune to thunder and force damage.
• You are immune to the frightened condition.
• You can use psychic powers to move in a way similarly to having the levitate spell cast on yourself.
• You have a +2 bonus to AC.
• You can use your reaction to parry a single melee attack adding a +5 to your AC.
• All your weapon attacks are magical, and when you make a weapon attack, you can use your spellcasting ability modifier, instead of Strength or Dexterity, for the attack and damage rolls.
• All your melee attacks and object interactions also gain a reach of 20ft. This manifests as black tentacles and can be used to similar effects as the telekinesis spell. 
• You can attack twice, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that gives you extra attacks.
