Blessed with resistance to magical and poisonous and fire effects, each of these yuan-tiefling's manifests their serpentine heritage in a variety of ways: a forked tongue, snake eyes, a snakelike nose, or some other ophidian characteristic. 

Creating Your Character

Ability Score Increases

When determining your character’s ability scores, increase three different scores by 1. Follow this rule to determine the scores, such as rolling or point buy. You can’t raise any of your scores above 20.

Your character can speak, read, and write Common and Infernal.

Creature Type

You are a Humanoid Hybrid.

Life Span

The typical life span of a player character in the D&D multiverse is about a century, assuming the character doesn’t meet a violent end on an adventure. Members of some races, such as dwarves and elves, can live for centuries. If typical members of a race can live longer than a century, that fact is mentioned in the race’s description.

Height and Weight

Player characters, regardless of race, typically fall into the same ranges of height and weight that humans have in our world. If you’d like to determine your character’s height or weight randomly, consult the Random Height and Weight table in the Player’s Handbook, and choose the row in the table that best represents the build you imagine for your character.
