This is what Solas said in response to choosing the Necromancy mage specialization:
Solas: You have begun practicing new magical forms. Interesting. You seem to be drawing energy across the veil, wisps too simple to be considered spirits. I believe Dorian uses similar magic, as do the Mortalitasi of Nevarra. Why did you choose such an esoteric area of study?
Lavellan: I hoped that studying such magic would help me better understand spirits.
Solas: While our fight affords little time for formal study, the wise can better themselves even in the midst of battle. Perhaps especially then. I hope your new studies serve you well.
Thanks for posting this. I chose necromancy and was walkin around, talking to people. It didn't occur to me that my inquizzy buddies would have something to say, but, Sera, Cassie, and Blackwall brought it up and were like. "eghhhh, we don't really like," so I was feeling annoyed! Then I thought, "Solas will understand!!!" I ran around the keep "Solas Solas Solas guess what? Guess what?" and I found him in his room "Guess what specialization I took?" *Click* His response?
S - "Hello."
Me - "Wait, didn't you wanna know what I can do now?"
S- "Vhenan."
Me - "Yeah um, honey that's cute but guess what? I'm a NECROMANCER!" *wiggling fingers*
S - "Vhenan."
Me - "It's gonna go great with all that electricity I do right? Purple!! Purple everywhere!"
S - "My Heart."
Me - *"Ugh, fine" *runs off* "Vivvy Vivvy Vivvy guess what ? Guess what?" etc etc
I assume there must be a limit or something of how many companions will talk to you about your spec? Because no one else said anything after that.. Except.. Hmmm I think Cullen may have. That dude has a lot of lines in this game.
