The Formless One (5e Subclass)
The Formless One[edit]
Warlock Subclass
You have made a pact with a powerful entity such as a deity, demon lord, or another supernatural entity that has power over slimes and oozes. You form a symbiotic relationship with your patron, by integrating a portion of your patron's slimy body within you, which in turn grants you supernatural power that you now wield. Slowly but surely, you are becoming one with your patron, but not before you channel its power for your great ambitions.
Since deities gain their power from their believers' faith, most of the gods of slimes and oozes are, in fact, as mindless and primitive as ordinary slimes and oozes. This does not make them less dangerous, however, for their ravenous hunger cannot be satisfied with mortal means.
Expanded Spell List[edit]
The Formless One lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.
| Spell Level | Spells |
|---|---|
| 1st | entangle, grease |
| 2nd | acid arrow, web |
| 3rd | meld into stone, stinking cloud |
| 4th | freedom of movement, polymorph |
| 5th | contagion*, passwall |
*Unless you gain this spell from another source, you can apply only Slimy Doom with it.
Amorphous Step[edit]
Starting at 1st level, your patron reveals to you the secret of walking and moving as an ooze does. Moving through difficult terrain, both nonmagical and magical, costs you no extra movement, and you ignore any obstacles and spells that affects you when stepped on, including ball bearings, caltrops, and the grease spell.
Corrosive Defense[edit]
Starting at 6th level, your sweat, blood, and other bodily fluid become viscous and acidic, which you utilize as a defensive system. When you are hit by an attack by a nonmagical weapon, the weapon is partly corroded and takes a permanent and cumulative -1 penalty to damage rolls. If its penalty drops to -5, the weapon is destroyed. Additionally, nonmagical ammunitions made of metal that hits you is destroyed after dealing damage.
Amorphous Resilience[edit]
Starting at 10th level, your patron's influence on you renders your flesh and organs resistant to acids and other corrosive substances, which now flows within your body. You are resistant to acid damage and you have advantage on all ability checks and saving throws against being grappled, paralyzed, and restrained.
Raise Ooze[edit]
Starting at 14th level, as an action, you can release built up slime within yourself by touching a dead creature, transforming it into an ooze-like duplicate of the creature. This creature is under your control. You can affect a creature of a Challenge Rating equal to your half your level, minimum 1, rounded down, that doesn't have Legendary Actions. This creatures creature type is ooze, its Intelligence score is 1, its Wisdom is 6, and its Charisma score is 1. It has all the natural abilities it had in life such as natural weapon attacks, resistances, and natural armor, however, it lacks the mental or physical capacity to use traits like regeneration, spellcasting, and innate spellcasting. You can only have one creature animated this way at once, and the ooze lasts for 8 hours, until you dismiss it as a bonus action, or until you use this feature again. You regain use of this feature once you have completed a long rest.
Unique Eldritch Invocations[edit]
Amorphous Armor (Prerequisite: The Formless One Patron)
As a bonus action, you can conjure a transparent membrane that covers your body for 1 minute. When you conjure the membrane, and at the start of each of your turn while you are covered with the membrane, you gain temporary hit points equal to your Charisma modifier (minimum of 1). You regain use of this invocation when you complete a short or long rest.
Corrosive Blast (Prerequisite: The Formless One Patron, 9th level, eldritch blast cantrip)
When you deal damage with your eldritch blast cantrip you can expand a spell slot to cause the blast to explode in a ball of acidic goo. Each creature in a 20-foot radius must make a Dexterity saving throw. A target takes 8d6 acid damage on a failed save, or half as much damage on a successful one. The goo spreads around corners. It melts objects in the area that aren’t being worn or carried.
Mucous Strike (Prerequisite: The Formless One Patron, 5h level, Pact of the Blade)
When you hit a creature with your pact weapon, you can cast the slow spell on that creature and up to 5 other creatures by expanding a warlock spell slot.
Osmotic Maul (Prerequisite: The Formless One Patron, Pact of the Blade)
As a bonus action, you can form a maul of crystalized ooze. When you hit a creature with it, you can expend a spell slot to deal an additional 1d8 acid damage to the target per level of the spell slot. In addition, and you temporary hit points equal to half the acid damage you deal this way.

You are always under the effect of the spider climb spell.
Slimy Explosion (Prerequisite: The Formless One Patron, eldritch blast cantrip)
Once during your turn when you hit a creature with your eldritch blast, you can cast grease as a bonus action without expending a spell slot. However, the spell must be centered on a creature you hit with eldritch blast.
Uncanny Metabolism (Prerequisite: The Formless One Patron)
Your body can digest and regenerate at tremendous speed. Whenever you finish a short or long rest. you gain temporary hit points equal to half your warlock level plus your Charisma modifier (a minimum of 1), as long as you are provided with sufficient food and drink.
Vibrant Perception (Prerequisite: The Formless One Patron)
