Lina looked her opponent over, sizing him up.  Armor, or maybe he was part golem.  Both a sword and a gun, which meant that he was probably good with both.  She was decent enough with a sword, but he would have a serious reach advantage.  If she could buy some distance, though, she could fight him at range where her defensive barrier could block his bullets.  Hopefully.

She put one hand behind her back and pulled back the one she hand offered as a handshake.  "In that case", she said, charging a light spell in her hidden hand, "may the best one win."

She stuck her now revealed hand in front of his face and yelled "lighting", hopefully blinding him long enough to get away.  She didn't bother checking, however, as she yelled "levitation" and began flying straight up.
