Slimefolk grow and mature incredibly rapidly. While no outsider has ever seen a newborn slimefolk, ones as young as five have been met, having already reached full maturity. Simmilarly, it is unknown just hold old slimefolk can live to. Given that they do not have the same biological processes as other races, it is believed that they may in fact not die of old age. Indeed, the oldest known slimefolk is well over 800 years old.

Slimefolk, given their natural propensity to serve, tend towards no particular alignment. Rather, they tend to adapt to the alignment of the group they are in.

A slimefolk's body is made of a gelatinous material. To the touch, they seem to be coated in a thin, viscous slime at all times. While they usually hold themselves together in order to interact with other races, they can, when needed, loose much of that cohesion. When hit by an attack, a slimefolk can grant themselves resistance to bludgeoning damage until the start of their next turn.

While the exact origins of the slimefolk are widely, and sometimes hotly, disputed, there is one thing that has been discovered. The slimefolk were originally a servant race. In time, however, they threw off their chains, the intervening years having built up their resistance to charms. Now, they are loath to be charmed, and harbor an innate distrust of any who use such magics.

Slimefolk are notoriously hard to kill. Even when unconscious, they don't loose their innate ability to hold themselves together. In addition, being struck while unconscious is much less of a threat, as they have no vital organs to protect.

Slimefolk are made of a gelatonous substance, which they have full control over. Because of this, they can remold their body. While it does take some time, and it is work, they can do it almost at will.

Slimefolk can cast Alter Self, only choosing the change appearance option, once per short rest. You cannot change your size to anything other than medium. In addition, your body will always appear to be coated in a thin layer of largely clear slime.
