The Vast (The Falling Titan) TMA

The Vast is the fear of insignificance within a vast empty space. It is a master of the skies and of space. It is rival to The Buried, for the empty void is the opposite of the crushing depths.

Ozone Blast

Starting at 1st level, when you cast Eldritch Blast you may thunder or lightning damage instead of Force damage. On a critical hit you may choose to forego the damage bonus to inflict a feeling of dizziness on your target, causing all terrain to count as difficult terrain for that creature until the end of your next turn.

Unknowable heights

When you choose this pact at level 1, you cannot take fall damage and you may cast Feather Fall at will without using a spell slot or material components, nor do you suffer any ill effects from vertigo or high altitudes.

Vertigo

From the 6th level you have learned to magically project the awe and terror of the void. As a bonus action when you make a melee attack you may touch a target, forcing them to make a wisdom saving throw. On a failed save, the creature is shown visions of the true size of the universe and their insignificant in this world, stunning them until the end of your next turn. You may use this ability a number of times equal to your charisma modifier, after which you may not use it again until you complete a long rest.

Expanse

From the 10th level, Your power reflects that of the all consuming void. When you cast a spell that affects an area with a radius you may double that area of effect. Once you use this ability you may not use it again until you complete a short or long rest.

Enjoy Sky Blue

At level 14 you may force a target to experience The Void. As an action you may force a creature that is outdoors that you can see within 60 feet to make a dexterity save. On a failed save the sky will reach down and swallow the creature whole. The creature then plummets through the infinite void of the sky, falling to the ground at the end of your next turn. For the purposes of calculating fall damage, the creature has fallen 1,000 feet in this time, and normal fall damage rules apply. Once you use this ability you may not use it again until you complete a long rest.
