Base Class: Barbarian
The Path of the First Ooze is reserved for barbarians whose fury manifests not as fire or shadow, but as an uncontrollable flood of raw, adaptable protoplasm. Whether through a bloodline touched by The First Ooze, a near-death encounter with a colossal sentient ooze in the Astral Sea, or by the nature of their Plasmoid ancestry, these barbarians tap into a primal, proto-life power. Their rage allows them to dissolve their rigid forms, becoming a terrifying engine of corrosive, amorphous destruction.
Level 3: Ooze Adaptation
When you choose this path at 3rd level, your rage begins to dissolve the boundaries of your physical form, granting you the following features:
Corrosive Hide. You gain resistance to acid damage and advantage on saving throws against being poisoned. Additionally, once per turn when you hit a creature with a melee attack while raging, you can deal an extra 1d4 acid damage.
Amorphous Flow. While you are raging, your body becomes naturally malleable and difficult to impede. You gain the ability to squeeze through any space that is at least 1 inch wide, provided you are wearing and carrying nothing. Furthermore, you can move through the space of any creature, hostile or otherwise, and that space is not considered difficult terrain for you.
Level 6: Engulfing Embrace
Your control over your shape improves, allowing you to use your body to trap and dissolve your enemies.
While you are raging, you gain advantage on ability checks made to initiate or escape a grapple. Furthermore, when you successfully grapple a creature, that creature is considered to be engulfed by your body and takes acid damage equal to your Constitution modifier (minimum of 1) at the start of each of your turns. This damage represents your corrosive form slowly breaking down the target's armor and flesh. While you are grappling a creature, you are immune to the Restrained condition.
Level 10: Adaptive Anatomy
Your transformation into an ooze-like state has eradicated any single, vulnerable point and freed you from the limitations of humanoid senses.
While you are raging:
-
Any attack that scores a critical hit against you instead becomes a normal hit.
-
You gain immunity to the Blinded and Deafened conditions.
Level 14: Primordial Form
At the pinnacle of your path, you tap into the self-regeneration and mutable defense that defines all oozes.
When you enter a rage, you choose one of the following damage types: bludgeoning, piercing, or slashing. You gain resistance to the chosen damage type for the duration of that rage.
Additionally, when you are reduced to 0 hit points while raging, you can immediately use your reaction to regain a number of hit points equal to 5× your Barbarian level. If you are still at 0 hit points after regaining these hit points, you automatically stabilize.
Once you use this recovery feature, you cannot use it again until you finish a long rest.
