Your feline agility and empathic instincts sharpen both your reflexes and your perception. 

Increase your Dexterity score by 2 and your Wisdom score by 1.

Chakats are tauric feline beings, averaging between 5 and 6 feet tall upright and 7 to 8 feet long nose-to-tail. Despite their frame, you are considered a Medium creature and occupy a 5-foot space.

Thanks to your tauric build and feline grace, your base walking speed is 40 feet.

Your feline half grants you natural climbing ability. You have a climbing speed of 20 feet.

Comfortable in water, Chakats swim with ease. You have a swimming speed of 20 feet.

Your feline heritage grants you sharp senses. You have proficiency in the Perception skill.

Your tauric build and supple torso gives you exceptional strength and reach. You count as one size larger when determining carrying capacity and the weight you can push, drag, or lift.

Your empathic nature let's you sense emotions. Once per long rest, you may roll with advantage on an insight check to gauge a creatures emotions or intentions. 

You can speak, read, and write Common and one other language of your choice. Many chakats also learn the tongues of nearby peoples or cultures.

Your tail is long, thickly muscled, and prehensile, averaging about 1.5 meters in length by adulthood. It serves many purposes: it braces and anchors your body, counterbalances your torso, and is strong enough to support your weight briefly or hold moderately sized objects. In combat, it can be used as a surprise weapon, though its lack of gripping surface makes it unsuited for wielding tools or delicate tasks. The tail can hold or carry items up to 15 pounds and can grant advantage on Dexterity (Acrobatics) checks made to balance or resist being knocked prone.

Your tail is also highly expressive, often conveying your mood or emotions. Among chakats, entwining tails is a sign of deep trust and intimacy. With age, a chakat’s tail continues to grow, and those with the longest tails are accorded the respectful title of Longtail.

Your hybrid physiology grants you greater resilience. You have advantage on saving throws against disease, and whenever you roll Hit Dice to regain hit points during a short rest, you may reroll one die and take the higher result.

In addition, minor injuries such as lost digits or superficial scars eventually heal over time. Regenerating major limbs is possible only with the aid of magic or advanced healing, though your natural resilience speeds this process. Your ever-growing tail is a subtle sign of this regenerative ability at work.

Chakats mature at a pace similar to humans, reaching adulthood in their late teens. Thanks to their hybrid physiology, they can live for up to a century and a half.

Your fur shifts between thick winter and thinner summer phases. While in your winter coat, you are well-insulated against cold and wind, gaining advantage on saving throws against nonmagical cold effects and avoiding penalties from snowy or windy weather. However, you are less comfortable in extreme heat and may require extra water or rest at the DM's discretion.

Your nails are thicker and more claw-like than a human's. Your unarmed strikes deal slashing damage equal to 1d4 + Strength modifier instead of the normal bludgeoning damage. 

Your mobile ears can detect a wide range of frequencies and faint sounds. You have advantage on Wisdom (Perception) checks that rely on hearing.

Your eyes are capable of perceiving near-ultraviolet, visible, and partial infrared light. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light, though only in shades of gray.

Your sensitive nose can detect subtle scents with remarkable accuracy. You have advantage on Wisdom(Perception) checks that rely on smell.

Your physiology allows you to store a nourishing fluid called milkwater, which helps sustain you during periods of exertion. Once per long rest, you can reroll one failed Constitution saving throw against exhaustion,  or gain advantage on one Constitution saving throw against fatigue, thirst, or starvation.

Your powerful lower body allows you to leap further and higher than other creatures. You have advantage  on Strength (Athletics) checks made to jump, and your jump distance is doubled when you take the Dash action.

Your forepaws have elongated toes witha semi-thumb, enabling you to hold objects crudely when seated or climbing. You may use them to carry or stabilize items, but not to wield weapons, shields, or perform delicate tasks.

Your dual stomachs and specialized enzymes allow you to digest nearly anything and resist toxins. You have advantage on saving throws against ingested poisons, and you can treat otherwise inedible plant matter as food for the purpose of survival. 

With dual lungs and a secondary set of vocal cords, you can project an incredibly loud roar or produce layered voices. You have advantage on Charisma (Intimidation) checks made by roaring, or Charisma (Performance) checks involving vocal projection. You can also purr, a sound often used for comfort or communication. 

Your dual hearts allow you to endure otherwise fatal injuries. When you drop to 0 hit points but are not killed outright, you may instead drop to 1 hit point. You cannot use this trait again until you finish a long rest.

Your harmonized nature grants you stability in thought and feeling. You have advantage on saving throws against being frightened or charmed.

Chakats remain vigorous and healthy well into their second century, with most only showing signs of age after 120 years. Though their bodies eventually slow, they are spared many of the infirmities that plague other species, allowing them to remain active until close to the end of their lives. Elders, called Longtails, are deeply respected in Chakat society. 

All chakats possess a natural empathic sense. As an action, you can focus on one creature you can see within 30 feet. You immediately sense its emotional state, such as fear, anger, joy, or calm, though not its specific thoughts. Once you use this trait, you must finish a short or long rest before using it again.
