Homebrew Astrazoan Species Details

With unclear origins, astrazoans have dispersed throughout the Material Plane and beyond to join the multiverse's cosmopolitan tapestry. However, astrazoans only rarely show their true forms to non-astrazoans. Instead, most live their lives as humans, elves and dwarves, preferring a semblance of anonymity and not wanting to shock their neighbors’ humanoid sensibilities with astrazoans’ peculiar appearances.

Astrazoans can climb and swim just like starfish and other invertebrates like octopi, however they do not have the ability to breath underwater like these beasts. They possess the ability to manipulate their form into narrower or pressed shapes, making them ideal for entering places that even some animals and monsters can't reach. 

Astrazoan Traits

Astrazoans can compress their bodies into small shapes and can even shapeshift to appear as other humanoids.

Compression

You can squeeze through a space as narrow as 1 inch wide, provided you are wearing and carrying nothing. You have advantage on ability checks you make to initiate or escape a grapple.

Change Form

As an action, an astrazoan can physically alter their form to look like any Medium creature, as long as they have seen a similar creature before. They can attempt to either mimic a specific creature or look like a general creature of the chosen type. The astrazoan can remain in an alternate form indefinitely and they do not change into their original form even when incapacitated; an astrazoan will only revert back to its original form once its HP has dropped to 0. This ability does not change clothes, armor or accessories on the astrazoan's person.  

Darkvision

You can see up to 60 feet in the dark or dim areas.
