Whether by luck, magic or a careful flurry of slices at a young age, you're now shaped as a pyramid instead of a cbe. You gain +2 AC to your base, but your hit die is now 1d8 instead of 1d10.

Awakened Gelatinous Cubes start with no equipment, including any that may have been granted from a Background. Everything in here will be extra wide. Tables, text, everything! Beware though, CSS columns can behave a bit weird sometimes.

After centuries of devouring adventurers (and their magical items) whole, this particular cube has awakened, becoming a new form of sentient being capable of rational thought. Along with rational thought, of course, comes existential crisis. Unsure of it's purpose in the world at large, Awakened Gelatinous Cubes set out to contemplate the cosmos in hopes of better understanding their place in the multiverse.

The gnome tiptoes his way across the stone in the dark hallway, sneaking towards the prized gem under bounty. He turns the corner and in enveloped in acidic gelatin, his screams silenced in the caustic mixture.

Slam

While it has gained sentience, the Cube has not learned the proper techniques for using weapons. Instead, it violently extends a portion of it's form to make a Slam attack. The Cube's Slam attack is +DEX to hit, dealing 1d4+DEX+Acid on a successful attack roll.

Iconic Body

The Cube is a legend among adventurer's and scholars alike. At first level, it loses any racial traits and features and gains the Ooze type, along with the following Ooze traits:

Cubes are blind, as they have no eyes, granting immunity to gaze attacks, visual effects, illusions and other attack forms that rely on sight. Cubes see with the Truesight ability out to 60 feet.

Cubes eat and breath, but do not sleep. They are immune to all sleep effects.

Being omnidirectional , Cubes do not suffer disadvantage as a result of being flanked or surrounded.

Cubes have learned to speak by vibrating their bodies to create sound waves that mimic speech. It can only speak Common at 1st level.

Instead of hands, the Cube can extend tendrils of goo to use for fine manipulation.

Instead of wearing clothing or gear, the Gelatinous Cube may “wear” or use magic items by enclosing them in protective air bubbles within it's form. It may only absorb one item for each body slot as normal.

Acidic Entity

Gelatinous Cubes endlessly excrete a corrosive acid. Any creature that is hit with it's slam attack, is engulfed by it or makes contact with it is dealt 1d6 acid damage per minute of contact. This acid can be applie dto objects and surfaces by touching them if the Cube chooses.

Hidden Hunter

Gelatinous Cubes are specialist hunters. While they generally have a green or blue tinge to their mass, this Cube can fade to near perfect translucency, granting them natural camouflage. The Cube may immediately make a Dexterity (Stealth) roll with advantage, even during combat. The Cube does not need cover or any other concealment to use this ability and may still move it's full speed without penalty.

Sacrifice The Body

The Cube can fling its acidic form as per the Acid Splash cantrip.

Engulf

Although it moves slowly, a Gelatinous Cube can simply envelop creatures of it's size or smaller as an action by simply moving over the target. The target must succeed on a Dexterity DC 10+DEX saving throw or be engulfed. On a success, they avoid the Cube altogether and move 5 feet to any direction out of the path of the Cube. Engulfed creatures are subject to the Cube's Paralytic Touch and Acid, and are considered to be Grappled.

Paralytic Touch

The acidic excretions of the Cube has become anesthetizing. A target hit by the Cube's slam or Engulf attack must succeed on a Constitution DC10+CON saving throw or be paralyzed. A creature affected by the Cube's Paralytic Touch may make a new Constitution saving throw at the end of each of their turns. The Cube can automatically Engulf a paralyzed target.

Hypercube

The sentient experience it has gained up to this point has allowed the Gelatinous Cube to ascend to be the Hypercube, Lord of Ooze. As the Hypercube, it is now immune to acid and poison, as well as resistant to paralysis and polymorph effects. It's Slam attack now deals 1d10+DEX+Acid damage, and it may alter it's own size from Large to Small, and the reverse, at will.

Aqueous Transmission

The Cube can now traverse water with a swim speed of 40 feet. Additionally, it no longer needs to breathe.

Survival Instinct

Since it's awakening, the Cube has experienced enough to expand it's capacity to reason, sharpening it's survival instinct. The Cube can now use his unarmored, amorphous form to his advantage, gaining an bonus to AC equal to 10 + DEX + WIS.

Mr. Cube's Wild Ride

The Cube's understanding of the world and it's increasing impact in it causes the Cube to transcend the mundane capabilities of normal Gelatinous Cubes. As it begins to abandon it's former dimensional boundaries, it begins by moving into three-dimensional space. The Cube gains a fly speed of 40 feet with perfect maneuverability.

Phase Body

The Cube's ability to shrug of the petty concThe Cube can repair its cellular structure at an alarming rate, gaining 1d10 temporary HP at the end of every round of combat.erns of the physical realm has reached its peak. As a reaction to an attack made against you, roll a d20. On 18+ the attack misses completely as your form nearly dematerializes from the plane you are in combat on. Otherwise, the attack connects as normal.

Reconstitute

The Cube can repair its cellular structure at an alarming rate, gaining 1d10 temporary HP at the end of every round of combat.

Resilience
