Homebrew Slime Species Details

Slimes - otherwise known as Awaken Oozes - are a sentient form of Ooze, one made with thoughts, emotions, feelings, and organs. Slimes have a gelatinous outer body, which is typically takes the shape of the race they first saw when they were born. Their form isn’t very solid, so it typically has bits and pieces dripping off back into itself, but the illusion is believable enough. The ooze has a consistent colour that’s decided by its creator. This colour makes up the entire body.

A slime is created by someone who has learned a form of transmutation mixed with a form of necromancy. The transmutation forms the gelatinous body of the slime, while the necromancy gives the slime its invisible and intricate nervous system and system of energy production. 

Slimes still require food to function, however, and their inner nervous systems activate on the slime’s command, releasing an acidic form of slime to digest the food. 

At the center of the nervous system is what is commonly known as the “life orb”. The life orb is what keeps the nervous system functioning, much like the brain or heart. The life orb is a glassy crystal orb containing blood and other essentials. When the orb is destroyed, the ooze cannot be brought back by any means short of a true resurrection or wish spell.

Gelatinous Form

If a creature tries grappling you, they have disadvantage on the roll. You can easily mold your body to fit through small spaces up to 6 inches wide.

Puddle of Slime

Once per long rest, you can create a 10-foot-radius puddle of slime originating from you. This area is considered difficult terrain to all creatures except for you. This slime doesn’t follow you around, and disperses after ten minutes. This feature changes your height to 4 feet once you use it.
