Slaad

Disappointingly, the most accurate description of a Slaad is that they cannot be described. Their bodies very closely mimic their home Plane of Limbo. Only their blood remains in its state, though it is unknown why. Some scholars believe this is what they use to infect humanoids, and hence it remains consistent, but it has never been proven.   The rest of their bodies are a constantly changing mass of every possible element, at every possible temperature. Their hide seems to retain some structure, even after death, though it is still wildly unpredictable, and must be handled with the utmost caution.

They have an incredibly confusing method of reproduction. Each Slaad subspecies has a different method and none can produce the same subspecies as themselves.   Red Slaadi have the ability to plant under the skin of any host they slash with their claws a Slaad Tadpole. If left unchecked, this Tadpole will fully grow into a new Slaad, bursting out from the host's chest at the end of its gestation period. This new Slaad will always be a Blue Slaad.   The Blue Slaad can infect anyone its unique claws cut into with a disease that will slowly disfigure and transform the creature into a Red Slaad. In certain circumstances, however, this may birth a Green Slaad. Green Slaadi are born if the host creature was capable of spellcasting or on random chance, though it's rare in those situations.   No other Slaadi directly reproduce, instead, they evolve under specific circumstances. Green Slaadi slowly transform into a Grey Slaad after some time. Grey Slaad can become a Death Slaad by consuming the corpse of another Death Slaad. It is unknown how a White Slaad is born, though it is confirmed that they are the next stage. Beyond that, there are folk tales of the Black Slaad, a creature of immense power, capable of facing Lesser Deities. None have ever been seen and the rumour is assumed to be a myth.
