Speaking with Astarion

When you bring Astarion to speak with her, she asks him to bite her so that she may study the effects of vampire bites up close. She offers a Potion of Everlasting Vigor in exchange, which permanently increases the Strength of the one drinking it by 2. Astarion does not wish to do this, because there is something wrong with Araj's blood, but he will do it if you ask him to, no ability check required (although he does disapprove).

Blood for Potions

Araj offers potions in exchange for True Soul blood. With a DC 14 Intelligence (History) check, you can determine that she wants Illithid blood rather than True Soul blood specifically, and if you reveal what you know of her intentions she'll up her offer to 200 gold along with each potion.

Each character may give blood once, taking a small amount of damage. The potion you receive depends on the race of the character giving the blood. As with standard elixirs, the effects go away when you take a long rest.

Unstable Blood

You can find Araj again in the Lower City of Baldur's Gate in Act 3. She will appear running out of an exploding house, just east of The Blushing Mermaid, and offer the player another potion in exchange for more blood. This potion, once drunk, causes the player to permanently gain the  Unstable Blood passive feature.
