Gelatinous Bloodline

You are the descendent spawn of Jubliex, an ancient being of slime and filth. Your corrosive flesh grants you protection from acids, whilst your relation to such beings allows you to communicate with them. By purifying your oozing flesh your heightened acids empower your magic and you gain the oblex's ability to eat memories. Eventually those who are born to this power are able to unleash the putrid hunger of the formless mass, an appetite that cannot be satiated.

Ooze Kin

At 1st level, you are able to telepathically communicate with oozes within 30 feet. You double your proficiency bonus for Charisma checks involving oozes.

 

Gelatinous Flesh

With your body adapting to its oozing magic, it causes your body to take on more of an slime-like form. Thanks to your corrosive flesh, you are now resistant to acid and lightning damage.

Aversion to Fire. Your new slimy flesh boils easily with heat, if you take fire damage you have disadvantage on attack rolls and ability checks until the end of your next turn.

Searing Acid

Starting at 6th level, your acidic essence infuses into your spells making your acidic magic more potent. When you cast a spell that deals acid damage, you deal additional acid damage equal to 2 plus the spell's level.

Consume Memories

At 14th level, your ties to the psychic oblex oozes grants you the ability to consume the memories of other creatures. You target one creature within 5 feet of you. The target must succeed on a Wisdom saving throw versus your spell save DC or take 5d6 psychic damage and it becomes memory drained until it finishes a short or long rest or until it benefits from the greater restoration or heal spell. Constructs, oozes, plants and undead succeed on the save automatically.

While memory drained the target must roll a d4 and subtract the number rolled from any ability check or attack roll it makes. When you cause a target to become memory drained, you learn all the languages the target knows and have access to the target's last week of memories. You can use this feature a number of times equal to your Charisma modifier, regaining all uses on completing a long rest.

Unfathomable Hunger

Beginning at 18th level, you can bring forth the endless hunger of your gelatinous ancestor. As an Action, you can spend 5 sorcery points to burst out ooze in a 30 foot radius and the area becomes difficult terrain for everyone except you. Any creatures you choose within this area must make a Dexterity saving throw, versus your spell save DC, when they start their turn inside the area. On a failed save the creature takes 10d6 acid damage and their movement speed is reduced to 0. On a successful save the creature takes half damage but retains its movement.
