Slimes do not age as other races do, and can theoretically live forever so long as they receive adequate nutrition

Slimes tend toward chaos due to their fluid nature, but may be anywhere on the spectrum of good and evil, depending on how they control their instinct to devour everything.

In their true form slimes range anywhere from 2 feet tall to 4 feet tall. Their girth almost always exceeds their height. It is rare for a slime to exceed even 60 pounds, with most weighing in between 20 and 40 pounds.

Your base walking speed is 20 feet. Most slimes make small hops to travel when moving at full speed.

You have blindsight to a range of 60 feet. You are blind beyond this range.

You do not eat or drink as most creatures do, but instead receive nutrients from material dissolved within you. You cannot become intoxicated from ingesting alcohol, and have advantage on saving throws against ingested poison. You do not sleep and magic cannot put you to sleep. Instead, you enter a torpor during which time you remain semiconscious, for 4 hours a day. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

You may also choose to devour a creature that died no more than 24 hours ago to gain their form for your Change Appearance trait. You may also gain a few important memories and a general idea of the creature's will and outlook in life, at the discretion of the DM. You can only do this once every 1d8 days  You can only remember a total of 5 different creatures. You may forget an old form to gain a new one.

As an action you may transform your appearance or revert to your natural form. You can't duplicate the appearance of an individual you've never consumed with your Devouring Mass trait, and you revert to your natural form if you die or fall unconscious. You decide what you look like,  including your height, weight, facial features, the sound of your voice, coloration, hair length, sex, and any other distinguishing features. Additionally, you always bear a general resemblance to the individual you consumed to gain the mimicry. You may choose to change into a creature up to one size larger than you, in which case you receive the bonuses and penalties associated with your new size category for the duration of your transformation. Your clothing does not transform with you. You may may also take on the appearance of a non-humanoid creature that meets the above criteria, but you do not gain any of its special abilities or stats.

You are proficient with your unarmed strikes, which deal 1d4 acid damage on a hit. You also gain resistance to acid damage.

Your fluid body allows you to move through spaces as narrow as 1 inch without squeezing. Non-magical restraints do not work on you, as you can just slip right out. Your racial type is Ooze.

Do to the fluid nature of your body, you cannot wear conventional armor or jewelry in your true form. Instead, you have a base AC of 13+Constitution modifier.
