The Ancient King

Deep beneath sand kings, queens, gods, and prophets are sealed away in ancient crypts. Due to dark rituals their spirits have been constrained to the mortal realm. You have made a pact with one such entity, maybe to learn the the ancient secrets and sorceries of a once lost civilization, or to barter your way out of certain death for trespassing on their domain.  No matter the details, you have now become an agent of this ancient being's will. With their presence being felt far beyond the reaches of their tomb.

Desert Shroud

Starting at 1st level, you suffer no ill effects of extreme heat and need half the normal water intake. Additionally, you may command the sand and dust around you. In addition, whenever you expend a warlock spell slot, you can choose to create a 10-foot radius sphere of whirling sands centered on yourself. You are lightly obscured to any creature beyond the sphere's radius. The sphere lasts for 1 minute and moves with you. You can dismiss it at any time using a bonus action.

The sand moves to protect you. While the sands move around you, grant yourself a +1 to your armor class. In addition, when a creature enters the shroud for the first time on a turn or starts its turn there it takes bludgeoning damage equal to your charisma modifier.

One With The Sand

Starting at 6th level, you can morph your body into sand for a brief time in response to harm. When you take damage, you can use your reaction to briefly become sand, gaining resistance to all damage until the start of your next turn.

Once you use this feature, you can't use it again until you finish a short or long rest.

Desert Storm

At 10th level, your patron teaches you greater mastery over the sands. Your Desert Shroud feature can be extended to a radius of 20 feet. In addition, you gain the ability to concentrate the sands to enhance their effects. When creating the shroud or as a bonus action on your turn, you can expand or concentrate the sphere to a radius of 20 feet, 10 feet, or 5 feet.

While the Desert Shroud has a radius of 20 feet, grant yourself a +1 to your armor class. In addition, when a creature enters the shroud for the first time on a turn or starts its turn there it takes bludgeoning damage equal to your charisma modifier.

While the Desert Shroud has a radius of 10 feet, grant yourself a +2 to your armor class. In addition, when a creature enters the shroud for the first time on a turn or starts its turn there it takes bludgeoning damage equal to your charisma modifier times two. Further, you are lightly obscured to any creature beyond the sphere's radius.

While the Desert Shroud has a radius of 5 feet, grant yourself a +3 to your armor class. In addition, when a creature enters the shroud for the first time on a turn or starts its turn there it takes bludgeoning damage equal to your charisma modifier times 3. Further, you are heavily obscured to any creature beyond the sphere's radius, and the sphere's space is difficult terrain for creatures other than you.

Grasp Of The Crypt

Starting at 14th level, you can entomb a creature in sand, subjecting them to your patron's domain. As an action, choose a creature that you can see within 120 feet of you. It must make a Dexterity saving throw against your warlock spell save DC. On a failed save, a sarcophagus rises from the earth and entombs the creature for one minute. The sarcophagus is immune to all damage, and cannot be opened from the outside. The creature entombed is considered blinded and restrained. At the start of its turn the creature takes 6d10 necrotic damage, as its life force is drained. An entombed creature can use its action to make a Strength save against your warlock spell save DC. On a success, it breaks free from the sarcophagus. You can release the creature at anytime using a bonus action.

Once you use this feature, you can't use it again until you finish a long rest.
