Since you had a trainer at your battle tower for your human skills, could be able to go see Patriarch to extend your dragon skills.
Yes, good idea that. Some of the dragon skills could have been extended; I only used about four at most inluding the healing spell. The Patriarch said something along the lines of "you are welcome in my lair anytime where no harm will come to our kind" well seem as he is so powerful, it would be nice to see more of him and gain his help. Surley he can't sit around in his lair and watch the world be destroyed? It would be in his best interest to help the dragon knight and Lucian despite his sit on the fence attitude. He seems to like the dragon knight but as far as Lucian goes, from what I can remember in Divinity 1 the Patriarch's parting comment was something like "leave before I rip your head off" after Lucian had unintentionally tricked him. It would be funny to see them two 'kiss and make up' in the sequel the kissing part probably involving the Patricarch's feet.
