[His mouth twitches a bit at 'Andraste's flaming ass', but he manages to more or less keep a straight face otherwise as he waits for her to finish the question. When he answers, though, he can't quite keep the corners of his mouth from turning up.]

Usually I'd say it's more of a dull sort of ache, but every once in awhile it's 'an Ice Warrior's hit me over the head and I'm just waking up from it' sort of pain. Usually after I use it to close a rift, but the worst of it goes away after a bit. It reacts when it's near rifts, too, though. That's different. It's more a sharp sort of flare then, and that's strong enough that'll it'll wake me up if I'm sleeping.
