The Desiccated Ones (Warlock Patron)

Patron: The Desiccated Ones
Desiccated ones are powerful beings from the elemental plane of earth. They are generally Dao, but may be any powerful earth elemental. Desiccated ones usually prefer to have servants who are stoic and take things seriously and have very little patience for foolishness. Warlocks of the Desiccated One's skin hardens slightly, while it does not actually protect them, it marks them as a servant of the Desiccated Ones. Desiccated Ones have a tendency to never release their warlocks from their pacts reagrdless of how much they do.

Expanded Spell List
The Desiccated One lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Control Sand
At 1st level, you know the mold earth cantrip, this counts as a warlock spell for you, but doesn't count towards your number of known cantrips. When you cast this, you can also use it to control sands that fit in the 5 foot cube. You have the following options with it:
 * Sand Blast - Make a ranged spell attack against a creature within the spells range. On a hit the creature takes 1d6 slashing damage and has disadvantage on its next attack. At 5th level, this spells damage increases by 1d6 at 5th, 11th, and 17th levels.
 * Sand Shield - You use the sand to create a small wall of sand to protect a creature in range, that creature gets a +2 bonus to its armor class until it moves out of the space, has an attack made against it, one minute passes, or you use this again.

Earthen Glide
Starting at 6th level, you gain the ability to move through the ground as the elemental you work for does. You gain a burrow speed of 10 feet. This increases by 10 feet at 10th and 14th levels. In addition you can ignore difficult terrain caused by rock and sand.

Blinding Sands
Starting at 10th level, when you cast a spell with earth or sand in its name, you can manipulate the spell to spray sand as well. If you do, any creature affected by the spell that fails its saving throw (or a Constitution saving throw against your spell save DC if the spell doesn't have one) is blinded until the end of your next turn. Once you use this feature, you cannot use it again until you complete a short or long rest.

Haboob
Starting at 14th level, as an action you can create a sandstorm to spring into existence centered at a point you can see within 30 feet of you lasting for 1 minute. The sand obscures vision giving partial cover within 5 feet and full cover from anything farther away for anything more than 5 feet away. Any creature that begins its turn in the area takes 4d8 slashing damage in addition it must make a Dexterity saving throw against your spell save DC or fall prone. This area counts as difficult terrain.

Pocket Sand
Prerequisite: The Desiccated Ones patron

When a creature within 5 feet of you makes an attack, you may use your reaction to throw sand in its face. It has the blinded condition until the end of its turn. Once you use this you cannot use it again until you finish a short or long rest.

Cloak of Sand
Prerequisite: The Desiccated Ones patron, 5th level

As an action you can call sands to swirl around you for 1 minute. Every creature that moves within 5 feet of you or starts it turn there must succeed on a Constitution saving throw against your spell save DC or be blinded as long as it remains in the area. Once you use this, you cannot use it again until you complete a long rest.

Dehydrate
Prerequisite: The Desiccated Ones patron, 11th level

when you cast a spell with earth or sand in its name, you can drain water from the creatures as well. Any creature affected by the spell that fails its saving throw (or a Constitution saving throw against your spell save DC if the spell doesn't have one) gains 1 level of exhaustion. If the spell has a duration, this only applies to the initial save a creature makes.
