Although doubtlessly intelligent, these nagas have more in common with normal snakes than most of their kind, preferring to be left to their own devices and lashing out at any creatures that would disturb them. A typical water naga measures 10 feet long and weighs 250 pounds. \n'b'  Migratory . Where many nagas claim particular lairs as their homes, river nagas typically have a number of retreats, migrating from one to the next with the changing of the seasons. These nagas keep elaborate summer and winter lairs, with several favored shelters positioned between these so they can make a circuit of familiar rivers and deltas throughout the year. Fiercely territorial when it comes to their lairs, river nagas typically attack any that intrude upon their sanctuaries, only bothering to question interlopers once such creatures have been weakened by poison, if at all. \n'b' As their yearly treks make many river nagas especially well traveled, those who live near the serpents\xe2\x80\x99 lairs- usually  lizardfolk , fey, and  human  tribes-often court the snake creatures\xe2\x80\x99 good graces with offerings of rich local delicacies, hoping to learn of nearby lands and pass on their own stories to distant neighbors. Enjoying flattery, exciting tales, and the adoration of those they see as lesser creatures, most water nagas take pride in their roles as travelers. However, while rarely malicious, they quickly grow bored of repetitive, mundane anecdotes and often embellish the stories they\xe2\x80\x99ve heard with their own fictions-caring little for the repercussions such misleading tales might cause for their listeners. The congeniality of some river nagas does not extend to the entire race, and many unwary souls, even those with only the best intentions, face these serpentine creatures\xe2\x80\x99 deadly bite.'
