Path of the Ooze

There is little more vile, more disgusting, and more gluttonous than the ooze. Barbarians belonging to the Path of the Ooze have strayed from the path of sane reasoning, and instead they serve only to feed and grow. The reasoning for these barbarian’s hunger varies extremely from Barbarian to barbarian. Some hunger for jubilex’s patronage in search for power, strength, and fulfillment. Others might be the result of a horrid arcane experiment gone horribly wrong or extremely right. And some might have been spawn of Jubilex himself given a scrap of sentience and a body to inhabit, but no matter the origin, these barbarians only know two things: fury, and hunger.

Ooze Speach

You gain the ability to comprehend the gestures and verbally communicate with Oozes. The knowledge and awareness of an Ooze is limited by their intelligence, but at minimum, An Ooze can give you information about nearby locations and monsters, including whatever they can perceive or have perceived within the past day. You might be able to persuade an Ooze to perform a small favor for you, at the GM's discretion

Ooze Magic

At 3rd level you gain the ability to use the Acid Splash cantrip at will even in rage, likewise at level 6 you gain Acid Arrow (2nd)  which can be cast a number of times per proficiency bonus recovered with a short or long rest. You can use both spells while in rage.

Glutton’s Fury

Starting when you choose this path at 3rd level, you can imbue your attacks with the acidic digestive juices. While you’re raging, your attacks deals extra damage equal to 1d4. The extra damage is acid. This damage increases to 1d8 at level 8, 1d10 at level 10, 1d12 at level 12, then 2d6 at level 14.

Consume

At 6th level, you start to eat as is fitting of an ooze. You may consume a non-living, non-metal creature/object or non magical object of your size or smaller, absorbing it and begining to digest it. When you are digesting, you must contain concentration for a minute as if you were concentrating on a spell(this is not effected by your rage however) and losing concentration makes you dispel whatever you are consuming. When you successfully digest, you are healed 1d4 hit point if the digested was tiny, 2d6 for small, 3d8 for medium, 4d10 for large,  5d12 for huge. Any healing that goes over your hit point maximum become temporary hit points that last until your next rest or until they run out. You may consume something in this manner only once per short rest.

Corrosive Rage

Starting at 10th level, your ooze can protect and enhance you. When you rage, you gain resistance to cold damage, and immunity to acid and poison damage along with your rage resistances. Additionally while in this form you are not affected by difficult terrain, and can fit through an opening one size category smaller than yourself. You also have blindsightwith a range of 30 feet. Within that range, you can effectively see anything that isn’t behind total cover, even if you’re blinded or in darkness. Moreover, you can see an invisible creature within that range, unless the creature successfully hides from you.

Corrosive Consumption

At 14th level, your acidic nature has become more corrosive.  Your Consume feature can now be used on living objects/creatures. To use on a living creature will require a successful Grapple check. If successful, you pull the creature into your space and consume them. If they fail the consumed creature can't breathe, is restrained, and takes 21 (6d6) acid damage at the start of each of your turns. When the you move, the consumed creature moves with you. A consumed creature can try to escape by taking an action to roll a contested Athletics check to escape your grapple. On a success, the creature escapes and enters a space of its choice within 5 feet of you.
