Twi'leks have lifespans equivalent to humans

Medium (about 4–7 feet tall) or Small (about 2–4 feet tall), chosen when you select this species

Your base walking speed is 30 feet.

You are a Humanoid.

You have Darkvision with a range of 60 ft.

You have Resistance to Poison Damage. You also have Advantage on saving throws you make to avoid or end the Poisoned condition.

You can use your lekku for sign language.
You can also use your lekku to pick up, push, or pull objects up to 20 pounds. Your Lekku can't wield weapons or shields or do anything that requires manual precision, such as using tools or magic items. 

You know Twi'leki, the secret language of Twi'leks. You can communicate non-verbally with other Twi'leks through a complex combination of verbal sounds and an elaborate, yet subtle sign language of head-tail motions. You and others who know this language automatically understand these signs. Others spot the message’s presence with a successful DC 15 Wisdom (Perception) check but can’t decipher it.

A Twi'Lek's Lekku is sensitive to the weave and can be used to replace specific components of spells. For each casting of a spell, the Lekku can be used to replace the somantic OR verbal component (only 1 component per casting). If a verbal component is replaced in this manner, the spell is considered to not contain a verbal component.

If the Lekku is being used to hold an item, it cannot be used to also replace a spell component.

You can speak, read, and write Common, Ryl, and Twi'leki. Ryl is the native tongue of Ryloth, yet there are few Twi'leks who cannot speak common fluently. What separates Twi'leks from other species is their second, nonverbal language called Lekku, or "Twi'leki." In everyday conversation, Twi'leks add texture and emphasis to their speech by moving and twitching their head-tails. If privacy is necessary, Twi'leks can converse in complete silence, using only the gestures of their head-tails to pass on complicated information.

A Twi'lek is naturally gifted in stealth, charisma and the arcane.
