2: Yes, he can conjure fire, but only a small amount of it. He could set some portion of a vampire on fire, and they’d have to stop for a sec to put it out, but they would not be unable to do so except under weird circumstances. Benjamin is, however, personally averse to combat applications for his power. He can put himself out if he’s on fire as long as he’s only a little bit on fire and not in pieces at the time. (Bella was in pieces when set on fire, both times.)
