Slime Core

Slime Core, Head of the Hivemind
True body of a slime is long snake-like organism no eyes and almost no internal organs. They are covered in dense green goo that helps them to move around and protects slime's real body. They have full control over their goo and use it to hold down their prey. Slimes prefer to live in dark and wet places, so their colonies can usually be found in caves, ruins or sewers. There is no upper limit of how big they can grow. Most of slimes never grow larger than 2-3 meters long because their nests are usually destroyed as fast as possible when found, especially near human settlements. Largest slime ever found was 15 meters long and group of 3 elite pyromancers slowly killed it over 4 days.

All slimes are connected in one hive mind with their Slime Core. They are basically one entity using many bodies at once and have no individual traits. Slimes are aggressive and territorial but quickly lose interest in chasing their prey.

Story
What is a society? A miserable group of individuals. Each with their own personality and goals. Many species tries to cooperate for the greater good: humans live in their cities, kharr defend their territory, wolfs hunt in packs, ants build their anthills, but none existing race can live in perfect harmony, none expect one. Snake-like creatures covered in toxic goop known as slime achieved peak of cooperation. What makes it so different from any other race is their minds, as there is no such thing like individual slime. Every single one of them shares one hive mind, driven by mutual goals. They are one being, separate fingers of one great organism.

The only flaw of this hive mind is that killing their Core will kill entire colony.

In-game
Slime Core is a tank with the highest sustain in the game. Every enemy death grants bonus health which can be converted into bonus healing, which leads to more enemy deaths and more bonus health. After getting initial kill participation Slime Core can snowball out of control very quickly and entire enemy team will be forced to focus all of their attention to shutting Slime down.
