TYPE: Mana Core.
Slimes are a quite simple species of mana core monster. They are very common, easy to kill and at the bottom of the food chain. They average 2 feet in length and width, with largest being around the size of a small deer.
They consist of a jelly-like body, sometimes an outer skin depending on the slime, and their mana core. Their body is slightly acidic, which is how they eat. What makes them special though, is the fact that they change depending on what they consume. And unlike other monsters, the possibilities for amount of changes they can undergo are endless. Even the slightest tweak in diet can change what type of slime they can become entirely, and new types of slimes are being discovered everyday, with 106 found as this is being written.
Due to this versatility, they are a very reliable resource for several things, including agriculture, food supply and even blacksmithing.
The most common types of slime are Water Slime, Regular Slime and Grass Slime. The edibility of a slime depends on what it's diet consists of, but most can be consumed if you are out of supplies, as the only off limit slimes are the ones you cannot recognize.
Note: NEVER eat a blood red slime, not even if you are desperate. A blood red slime is a slime that will eventually evolve into a mimic, and since there is virtually no difference between a slime that will become a monster mimic and one that will become a human mimic, you'll never truly know if you just ate monster flesh, or became a cannibal by proxy.
Mimics themselves are mostly harmless as they use their disguises to lure in much bigger and more suitable prey than humans, but in an environment that lacks large prey, they can become a hunter of solely humans. And the more humans a mimic eats, the more human it becomes, until it evolves into it's second demi human form.
