Homebrew:The Great Ooze

(OOC: This is an implementation of The Great Ooze subclass from Tasha's Crucible of Everything Else volume 2)

Base Class: Warlock

Your patron is an ancient and powerful ooze. Unlike the average ooze, whose existence is driven by mindless consumption, your ancient patron has developed powerful psychic abilities and has bestowed the traits of their unusual form upon your body. Often these entities will sow their yearning for destruction within you, compelling you to seep your way into the world on their behalf.

Beings of this type might include one of the original offspring of the demon lord Juiblex or a denizen of the Swamp of Oblivion - the para-elemental plane of ooze. In Eberron, Kyrzin the Daelkyr is one such being. It could also be an ooze from a time before even the gods - primordial leftovers from the soup of creation.

Amorphous Form

1st-level The Great Ooze feature

As an action, you can alter your form to temporarily become ooze-like. For 10 minutes you gain the following benefits:

• You can move through a space as narrow as 1 inch wide without squeezing.
• You gain a climbing speed equal to your walking speed.
• You can occupy the space of other creatures and vice versa.
• You have the ability to communicate with oozes as if you shared a language.

Once you have used this feature, you cannot do so again until you finish a short or long rest.

Pseudopod's Reach

1st-level The Great Ooze feature

Your limbs can take on an unnatural, ooze-like quality. As a bonus action, you can make a melee spell attack against one creature within 10 feet of you. On a hit, the target takes acid damage equal to your Charisma modifier.

Engulf

6th-level The Great Ooze feature

While in your Amorphous Form, a creature that starts its turn in your space takes 2d6 acid damage and is restrained. A creature restrained in this way can try to escape by using its action to make a Strength saving throw against your Warlock spell save DC. On a success, the creature escapes and enters an unoccupied space of its choice within 5 feet of you.

Acidic Defense

10th-level The Great Ooze feature

You are immune to acid damage. Additionally, when a creature within 5 feet hits you with a melee attack, you splatter. As a reaction, you can force the attacker to make a Dexterity saving throw against your Warlock spell save DC. On a failed save, it takes acid damage equal to your Charisma modifier.

Erode

14th-level The Great Ooze feature

You are able to rain down corrosive globules, reducing the effectiveness of your foes' armor and weapons. As an action, choose a number of nonmagical weapons or suits of armor that you can see within 60 feet of you, up to your Warlock level. If the target is a weapon, it receives a -2 penalty to attack and damage rolls. If the target is a suit of armor, it receives a -2 penalty to the Armor Class it provides. These changes are permanent, and can only be applied to an object once.

Once you use this feature, you can't do so again until you finish a long rest.
