1. Jordeira would choose "silence". If someone upsets him, congratulations, you've lost your voice. If someone shares an opinion that he doesn't agree with, then oops, you won't be saying anything else. Basically, having that spell would give him a way to quiet his rivals that doesn't involve punching them in the throat. Kina would choose "beast shape". It's not practical for day to day life, but Kina enjoys having the ability to shrug off responsibility and simply exist for awhile. If things become too stressful, she can turn into a cat and lounge in a patch of sunlight. If her emotions are getting the best of her, she can become a bird and take to the skies.   2. It doesn't take much to upset Jordeira, but the easiest way to do so is to insult his intelligence...or point out his insecurity about his height. He likes to tell himself that he's gotten better at controlling his temper, but one well-aimed insult will earn his wrath immediately. The easiest way to provoke Kina is to threaten or insult those she cares about. She can be quiet and sad when insulted directly, but the second that anything is directed at her loved ones, she's in the instigator's face and telling them off.   Bonus: Kina's cousin, Cat, is very interested in the Feywild and has studied it and its inhabitants for years. When Kina was much younger and started to express interest in her studies, Cat taught her all that she could, including the sylvan language. Draconic was learned from her grandmother, who believed that it was the "proper" language of magic. Kina can speak infernal innately due to her fiendish blood, but it wasn't something she truly realized until adulthood. Necril is another language she has innate knowledge of due to her time as a living phylactery. After losing that status, her grasp on necril is shakier. In adulthood, she's also learned to speak elven and celestial. Rikius taught her some elven and she took a formal class for it. Industria taught her celestial during the party's military days.   Jordeira learned abyssal from the scholars among the cult he was raised in. They also taught fragments of necril, but he gained a full understanding of the language after he became undead. He can speak undercommon, which was something he studied in his free time when he was alive. Jordeira also knows some drow sign language, which he learned from a refugee of Niffelheim that he befriended.
