Monkey see, Monkey Please don't

An excerpt from the Imperial Bestiary of the Howling Sky Dukedom.

...

In the jungle ruins of the Quivering Leaf Empire, there is a species of monkey known as the Martial Mimic Monkey.

This strange monkey has the uncanny ability to copy any aether art it has witnessed once, down to a near perfect degree.

To an extent.

The quality of the aether arts this species can mimic is highly dependent on their individual tier.

A majority of these monkeys only ever reach the Third Tier, making them able to mimic major Corporeal arts at best.

However, it is believed that if a Martial Mimic Monkey ever reaches a higher tier then they would be able to mimic even more powerful aether arts.

Of course, such a thing is completely pure speculation due to the fact that no third tier Martial Mimic Monkeys exist in any capacity, natural or otherwise.
