High in the jungle canopy lives a primate that anwsers the question you are what you eat. Generations of consuming their favorite food the Imperi Fruit have caused their bodies to undergo metamorphosis. What was once a fully organic creature became corrupted by the magic of the fruit, turning parts of their body into that of a plant. Besides just taking on aesthetic qualities such as leaf ears or bark skin, the tail has a more special quality. It releases some sort of hallucinagenic powder that causes anyone who is exposed to see multiple copies of the chimp, making it hard to keep track of where the real chimp is. Whats remarkable is that the Imperi fruit normally takes over the mind of whatever tries to consume it but the chimps seem to have some kind of natural immunity to the fruits magic. Make no mistake though eating this fruit has clearly driven them mad. While they see each other with a familial instinct, any other creature can expect to be met with extreme hostility. Almost as if the fruit is still yearning to be brought towards a being it can truly control.
This CR1/2 creature is called a Channeler Chimp and is a Monstrosity that lives mostly within the Tropical Rainforest.
