Slimoids are diverse, but the lack of internal structure limits their strength. You have -2 to your strength score, but +1 to two other scores of your choice. They must be different scores.

Some Slimoids are bigger than others. Their mass is recycled over and over throughout the day as they shed and gain matter. Your size is medium or small. If you choose medium, your Constitution score increases by two. If you choose small, your Dexterity score increases by two. You can change your size category when you take a long rest, and your ability scores will change accordingly.

You can move through any space a liquid could pass through. Additionally, as an action, you can morph your body into any sort of humanoid shape you like, though this shape confers no special benefits. Unless a spell similar to Alter Self or Disguise Self is cast on you, you will always retain your semi-transparent and wet, drippy appearance.

In addition to humanoid shapes, as an optional part of this action you may extend up to 8 slimy tendrils from your body. These tendrils have the capability to grapple, but you can only grapple two creatures at a time, regardless of number of tendrils and whether your arms are free. Each tendril can pick up and hold an items weighing up to 3x your strength score. Items carried in this way count towards your total lift/carry amount. [Example: a slimoid with a strength of 12 can carry 36 pounds in each of its 8 tendrils, but still is limited to a total carry load of 180 pounds.] The tendrils can perform simple actions (lift, drop, push, pull) but cannot wield weapons or shields, or use items or tools that require precision.

These tentacles normally come from under the arms, the sides, the back, the shoulders, or if your form mimics long hair, from that.

You can use 10 feet of your movement action to end the grappled or restrained condition. Your base walking speed is 20, but you ignore difficult terrain, as well as have a climbing speed and swimming speed equal to your walking speed

You can breathe air and water. Also, you breathe through your skin, meaning you can’t suffocate unless you are placed in a vacuum or are completely smothered.

Born from elemental chaos, you are resistant to damage based on the circumstances in which you came into being. Choose one damage type from Acid, Cold, Fire, Force, Lightning, Necrotic, Poison, or Thunder. You have resistance to this type of damage. Additionally, you are immune to all diseases except for Water Blight.

Due to your slime nature, you are vulnerable to slashing damage.

When you drop to 0 hit points but are not killed outright, you can use your reaction to instead collapse into a slimy puddle(large if your size is medium, medium if your size is small) with 1 hit point. When in this state, you are indistinguishable from a dead Slimoid, and if a creature tries to identify you as dead or alive, they must pass a DC 15 arcana check. The area of this puddle functions like it’s under the effects of grease, with a save DC of 8 + your constitution modifier + your proficiency bonus. You may use this reaction once per long rest. But, you can enter your puddle form at any time as an action, without dropping to a single hit point. You can return to your humanoid form as an action.

The fluids that comprise your body are very nutritious. You taste and smell like a pleasant, sweet flavor of your choice. You can reduce your hit point maximum as an action to remove or expel a part of yourself, separating an amount of goo equal to one day of rations per hit die spent. For each hit die spent, roll the die and subtract it from your maximum HP. Your HP maximum returns to full at the end of a long rest. Likewise, hit dice spent in this way are regained at the end of a long rest even if it would exceed the maximum number normally allowed.

Hit dice spent in this way still count towards total hit dice spent, and are recovered first. [Example: A 12th level slimoid spends 5 hit dice on creating rations and 3 on healing themself. At the end of a long rest, they would regain all five hit dice from rations, and one used normally.]

Born of natural forces, you can speak, read, and write Common, Primordial, and another language of your choice.
