Sorcerous origin: Where others see forces of nature that bring nothing but destruction, you see gelatinous allies and companions. Regardless of good sense and the way it makes your skin crawl, your fondness for oozes has granted you a supernatural understanding of the creatures.
At 1st level, you master the conjuration of a strange fungus called chimatuluka. Oozes crave chimatuluka and when adjacent to or hit with as much as a handful, mindlessly consume it for a number of rounds equal to half your proficiency bonus (completely ignoring creatures attacking it). By spending 10 minutes focusing your magical energies, you create a number of handfuls of chimatuluka equal to your proficiency bonus + Charisma modifier.
You learn the find familiar spell and can cast it as a ritual. The spell doesn’t count against your number of spells known. When you cast the spell, you can choose one of the normal forms for your familiar or use a handful of chimatuluka as a spell component to choose a gray ooze. Oozes you summon move extremely quickly, increasing their speed to 25 feet. Each time an ooze is summoned it must be fed chimatuluka, and after 1 hour and every hour afterward you must feed a summoned ooze one chimatuluka or roll 1d20. If the result is less than your sorcerer level the ooze consumes itself and dissolves into nothingness but otherwise it attacks the nearest living creature.
Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one attack of its own.
Also at 1st level, your body changes to become more ooze-like. Whenever you suffer a critical hit or take extra damage such as from a rogue’s Sneak Attack or a hobgoblin’s Martial Advantage, roll 1d20. If the result is equal to or less than your sorcerer level, you ignore the extra damage dealt by the attack.
Beginning at 6th level, you may use three handfuls of chimatuluka to summon a gelatinous cube or ochre jelly with find familiar.
Starting at 14th level, when you are reduced to half your maximum hit points, your viscous blood coalesces into a black ooze that attacks creatures hostile to you. This ooze acts on your initiative, and dissipates at the end of your turn if it cannot sense any hostile creatures, or after 1 hour passes, whichever is sooner.
You must complete a long rest before you can create another black ooze.
At 18th level, you can use your action to magically assume the shape of an ooze. This functions as a druid’s Wild Shape feature (using your sorcerer level as your druid level), but you can only transform into creatures of the ooze type. Additionally, by expending 1 sorcery point per two spell levels (minimum 1 sorcery point) you are still able to take the Cast a Spell action while in ooze form. You can use this feature twice, and you regain all expended uses when you finish a long rest.
