Your Constitution score increases by 2 and a score of your choice increases by 1

A typical oblex is 'born' fully grown and shows no outward signs of aging. The maximum lifespan of a fractured oblex is not currently known. Oblexes are immune to magical aging effects.

Fractured Oblexes can vary in size depending on the creature who's form they are assuming, but they are unable to shrink to less than 2 square feet or more than 5 square feet. Oblexes are genrally heavier than their appearence suggests.

An Oblex's base walking speed is 20 feet.

You can perceive your surroundings within 60 feet of you without relying on sight. Beyond this you are blind.

You do not require sleep, and can not be blinded deafened exhausted or prone. 

*While in their Ooze form, fractured oblexes are unable to hold weapons and are unable to speak. 

Oblexes can speak, read, and write Common, and Undercommon.

As a Fractured Oblex, you are weak to fire based damage.

You can use your action to attack and try to consume the memories of a foe.

When you use this ability, target one creature you can see within 5 feet of you and have them make a Wisdom saving throw. The DC for this saving throw equals 8 + your Intelligence modifier + your proficiency bonus. On a failed save the creature takes 1d6 psychic damage.

The damage increases to 2d6 at 6th level 3d6 at 11th level and 4d6 at 16th level

If you bring a target to 0HP with this attack, you completely drain their mind and steal their memories, leaving them mindless husks instead of dead.

(non NPC characters will need to fail all 3 death saves before being absorbed.)

 When an oblex succesfully devours a creatures memories, they are stored as Psionic energy that provides nourishment to the oblex. The psionic energy is generally fully digested within about a week. If an oblex wants to create a 'child', they will need to stockpile memories from 4-5 creatures and disgorge them as an oblex spawn before they are digested.

You may remember the form of a number of creatures you've left husks, equal to your proficiency modifier, and can replace one should you meet this limit.

As a bonus action, you can form yourself into the appearance of one Medium or smaller creature who's memories you've eaten within 24 hours, or one of your remembered forms. This simulacrum appears, feels, and sounds exactly like the creature impersonated though smells faintly of sulfur.

While impersonating a creature, you lose your ooze nature and blindvision, but gain regular vision and speech.

After draining or stealing a creature's memories, you may gain a single one of its languages or proficiencies while in it's form. After choosing which language or proficiency you take from the creature, you can not change which one you gain.
