Demon Prince Juiblex

Your patron is the Demon Prince of Oozes, Juiblex.  Also known as the Faceless Lord, Juiblex has a singular drive to consume.  His every thought, action, and desire is bent towards the absorption and dissolution of the world around him.  Juiblex knows no allegiance and makes no concessions in his quest to devour.  It is exceedingly rare for this Demon Prince to make vows or pacts of any kind.  But on rare occasions, when he finds a creature with a drive as stubborn and singular as his own, he becomes willing to share a part of his power.

Vile Liquescence

Beginning at 1st level, your body is already affected by the pact you have made.  You have advantage on ability checks made to grapple other creatures, and on checks made to escape another creature's grapple.  Creatures you are grappling with take 1d6 acid damage when the grapple begins and again at the start of each of your turns while you are grappling them.

You also have advantage on checks made to escape restraints such as ropes, cuffs, or chains.

Starving Madness

Starting at 6th level, you are able to infect others with a small sliver of your patron's great hunger.  As an action on your turn, select a number of creatures up to your Charisma modifier (minimum one) that you can see within 60 feet of you.  The target creatures must make a Wisdom saving throw against your spell save DC.  Creatures that do not require food, such as constructs, automatically succeed on their saving throw.  On a failure, the target creature is driven mad with hunger, and must use its Reaction to move up to its movement speed towards the closest creature and make one weapon attack against it.  If it cannot reach another creature with its movement, it still moves but does nothing with its action.

You may use this feature once, regaining the ability to do so after a long rest.

Acidic Film

Starting at 10th level, you can cover your skin in a defensive layer of acidic slime.  As a Reaction when you take bludgeoning, piercing or slashing damage from a nonmagical weapon, you may grant yourself immunity to that instance of damage.  If the damage came from a melee weapon, that weapon is damaged by your acid, receiving a permanent -1 to attack and damage rolls made with it.  If the weapon accumulates damage to a -4 modifier, it is destroyed.

You may use this feature a number of times equal to your Charisma modifier, regaining expended uses after a long rest.

Oozing Form

By 14th level you can alter your body to imitate that of your patron.  As an Action on your turn you can assume the form of a medium-sized ooze.  The ooze retains your basic shape, but is semi-transparent and brightly colored.  While in this form you can move through gaps as narrow as one inch without squeezing and have a climbing speed equal to your walking speed.  You can climb vertical surfaces and even upside down on ceilings without falling.  While in this form you are also immune to acid damage.

While in your ooze form you can move through the space of another creature.  When you do, that creature must make a Dexterity saving throw against your warlock spell save DC.  On a failure, the creature takes 5d10 acid damage and its movement speed is reduced to 0 until the end of its next turn.  On a success it takes half damage and its movement speed is not reduced.

At the end of your turn your body reverts to its original state.  If you are in a space too small to accommodate your size, you are shunted to the nearest space that can, taking 1d6 force damage for every 5 feet you move.  If you end your turn on a vertical surface or upside down on a ceiling you fall, taking 1d6 bludgeoning damage for every 10 feet you fall before landing.  If you end your turn in the same space as another creature, you emerge in an adjacent space of your choosing.  If you choose, you may grapple that creature automatically.

You may use this feature once, regaining the ability to do so on a short or long rest.
