Homebrew Evolver Species Details

Evolvers are anomalous beings that can absorb creatures and turn into them, more on this later, their limit at their highest level is unlimited, but early on they have 3 forms available to them, they have the following limits

3 forms aside from birth form at max at start, more are gained per level up or if the dm decides conditions to hold more are met. A certain amount of organic material needs to be "consumed" for the form to be obtained, the amount needed varies. Abilities can only be gained while in that form, minus a single rarely gained passive ability, recessive traits are a % chance to be gained. (Dms discretion or d100 roll.) Mutations can occur when the form is obtained, which can be good or bad or useless, for example there is a long lost record of a purple evolver, and black evolver, these records have been lost along with all knowledge of the race, those that do know of them believe them to be extinct. 

Please note that this concept is based off of the primals from the last primal, and as such is very much my own take on it, I do not own the last primal novel, or the idea of the primals, I am only doing my best to make a fun knock off, if the author wants me to take this race down I will, once I find out how, however they will need to provide proof that they are actually the author as I don't trust people and would rather be sure

Language

They innately can speak common from birth, for convenience once they get a humanoid form, they can't speak in their birth form, as they are a slime

Slimelike

As you are a slime you have potebt acid that you use to devour and absorb prey, though it's contained and won't leave you unless you wish it to, however you can't use this to attack unless something is inside of you, this acid does the same amount of damage as regular slime acid does (1d8) this can corrode metal or tough materials fairly quickly

Resistance/Immunity to acid

At level 1 they are resistant to acid, at level 7 they can't be harmed by acid

Vulnerable to slashing and piercing

They are vulnerable to slashing damage and piercing 

Flailing limb

They are able to grow a whip like appendage, which they could use to bludgeon, restrain, or well, whip, their prey, this does 1d6+strength/dex, depending on how you use it

Natural armor

Did you think they would be squishy easy to kills? Nope! You can't just pop them like a balloon,
