Cruel and devoted to the Serpent God, the snake-men are strong predators and feared by all the races that cross their path, daring and adept at the art of killing, are excellent assassins, sorcerers and hunters, privileged for possessing the power of poison, which incidentally is the main characteristic of its civilization, everything revolves around its poison, its spirituality, its economy and its armies. From an early age, they are initiated into the Poison Cult, paying eternal loyalty to the Serpent God, declaring war on all the other clans of the snake people who worship the Serpent God in different ways, one of the great reasons why they are immersed in a religious civil war that lasts for many years, but even so they unite when an outside race tries to intervene in their customs and traditions that can sound sinister and "inhuman".
Racial:
Poison Cult: "Wrap your powerful poison in your private weapon".
By the serpent God: "It feeds on the body of the dead enemy restoring a certain percentage of life".
Predator instinct: "Attack speed increased".
That's a very nicely written concept you did there. Sounds very good!
