Yuan - ti pureblood Purebloods were the most human - seeming of all true yuan - ti and one of three main breeds — the other two being the halfbloods and the abominations . Description . Purebloods were described as human - like but with minor reptilian features , such as snake - like eyes , a forked tongue , and patches of scales on their skin . Purebloods had weights and heights in the same range as human s . Abilities . While not as powerful as other yuan - ti forms , purebloods still had psionic powers . Like all yuan - ti , they could morph their bodies into the form of any viper by force of will alone and could sense the presence of any poison nearby . They were also innately resistant to magic . They were not as intelligent as halfbloods , yet they still took pride in being more intelligent on average than humans . The psionic powers of purebloods included the ability to charm other humanoids , to entrance animals , to cause fear , to create darkness , and to command plants to entangle opponents . Purebloods were very adept at impersonating humans , and often entered human settlements in disguise as spies . Life Cycle . Pure bloods could mate with halfbloods or abominations but usually did not . Like other yuan - ti , they hatched from eggs and reached adulthood by twelve years of age . An average lifespan for any yuan - ti was 80 years , but attaining an age as great as 120 years was possible . Personality . Despite being thoroughly wicked , the majority of purebloods had magnetic personalities . Like all yuan - ti , they tended to be arrogant and self - centered . Purebloods were the least likely of the true yuan - ti breeds to remain attached to their tribe . Since they could more easily disguise themselves , they had the freedom to pursue their own interests wherever such things took them . Purebloods were the most likely yuan - ti to use grafts to modify their bodies , provided the new serpentine body parts could still be easily hid with magic or underneath clothing until " needed " . Combat . Yuan - ti were perfectionists , and only used high - quality weapons . They would rather weaken a foe from a distance than engage in melee combat . If a fight came to that , however , the purebloods would be sent in first as the more powerful and " valuable " yuan - ti waited . Purebloods were often equipped with studded leather armor and bore scimitar s and heavy shield s or longbow s They often poisoned their blades and arrows . Purebloods who were trained in combat favored the skills of ranger s . They were naturally dextrous . Society . Purebloods served a special role in yuan - ti society by being the liaisons , agents , spies , or assassins , as they could usually readily hide their serpentine features . They also oversaw the " lesser " yuan - ti servitor subraces , the broodguard s and tainted one s . Language . Purebloods spoke the Yuan - ti language , Common , and any regional languages . They often could speak Abyssal or Draconic as well . Religion . Purebloods , like the majority of yuan - ti , worshiped the god Sseth . Free - wandering purebloods sometimes worshiped the god Varae instead . Some sects were known to worship demon s . History . The sarrukh , one of the creator race s , created the yuan - ti , including purebloods , millennia ago in controlled magical breeding experiments combining humans , serpents , and sarrukh themselves . Appendix . Trivia . Purebloods were a playable race in the Neverwinter Nights 2 expansion .
