While Gill and Gian's fight was ongoing, the rest of the team cleaned up the battlefield and tied down their new victims.
In fact, there were a lot of people in this team, about 20 fighters being trained by about half a dozen level 15 mercenaries and a few level 20s. If it was another team, they'd definitely have a lot of trouble.
But their team had Oslo, who also happened to be a dual-elementalist.
He dealt with half of the level 20s and at the same time assisted the others. They also used a few of their weapons here in order to save energy for the main battles, but also to test out their weapons.
The enemies definitely did not expect the rain of crossbow arrows they got showered with. The level 15s were not unhurt, let alone the weaker ones who were skewered like those styrofoams poked with hotdog sticks in kids' parties.
