Calamarens tend to grow and mature quickly, reaching adulthood as early as 10 years of age. They have relatively shorter lives, roughly 80 years at the longest.

Calamarens range in size drastically from individual to individual. They can be a small and squat 3 feet tall to a long and lanky 8 feet. Your size is medium.

Calamarens find it difficult to walk on land, but are exceptional swimmers. Your base walking speed is 30 feet and your base swimming speed is 30 feet. Calamarens also possess the ability to breathe underwater.

You can speak, read, and write Common, and Aquan. The Calamaren dialect of Common is a slow and "smoothed-out" version of Common.

All Calamarens are able to spray a thick cloud of black ink to protect themselves when they are in danger. As a reaction, you shoot out a cloud of ink at a creature attacking you. That creature becomes blinded by the ink until the start of your next turn. You can use this ability a number of times equal to your proficiency bonus per long rest.

All Calamarens are capable of producing beautiful displays of light through bioluminescence. As a bonus action, you may shed bright light in a radius up to 30 feet, and dim light up to another 30 feet. You choose the color of the light when you shed it, and can choose to change the color at will.

Calamaren have long, gripping tentacles that they can extend outwards to grab their prey. You have an additional 5 feet of reach, which includes your melee attack range.
