Your Constitution and Wisdom both increase by 1. In addition, one ability score of your choice increases by 1.

Lamia reach maturity around the same time as humans, but may live to upwards of 200 years.

Lamia tend toward neutral alignments out of their tradition of keeping to themselves, although those Lamia who do lead a life with other races often adopt the alignment of their community.

While in a resting position Lamia are slightly taller than humans, standing between 6 and 8 feet in height. Your size is medium. The unique anatomy of the Lamia however necessitates an additional 5 feet of occupied space behind them for their long, muscular tails. By rearing up on its tail a Lamia may double its height, but sacrifices all speed besides climbing speed while in such a position.

Your base walking speed is 30 feet. You also have a swim speed equal to your walking speed, and a climb speed of 20.

Because of your muscular tail, you have a swimming speed of 30 and a climbing speed of 20 feet. In addition, your tail is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal bludgeoning damage equal to 1d6 + your Strength modifier. Alternatively, your tail may be used to make an attack action to grapple a creature, following normal rules regarding grappling. If successful, the creature is left constricted by your coiled tail until they succeed on a contested grapple check to escape. A creature that ends its turn this way takes 1d6 + your Strength modifier bludgeoning damage, if you wish to harm it. You may not make unarmed attacks with your tail while it is being used to grapple.

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. While in darkness, you perceive your surroundings in a thermal spectrum, with living creatures and warm surfaces unhidden by magic or thermal camouflage appearing as heat signatures due to your pit organs, but you cannot otherwise discern color in darkness.

Your forked tongue and pit organs are fine-tuned to living creatures, granting you the superior hunting abilities of a serpent. You have advantage on Wisdom (Survival), Wisdom (Perception), and Intelligence (Investigation) checks to track or locate living creatures, or follow their trails. Additionally, you have proficiency in the Survival skill.

You have disadvantage on Constitution saving throws against spells that deal Cold damage, and have disadvantage on Constitution saving throws made to withstand environments of extreme cold.

You can speak, read, and write Common and Draconic.
