Luke began to experiment with water magic without wasting time since trying an earth spear would probably take quite a while to learn. The only problem with that was that Luke would take a lot more time to make the Water Arrow since it was trying to mix the water particles in the air… to do that faster, he would need a body of water nearby, and he couldn't see any. Before he could find a solution to that problem, he saw some dark elves returning. A couple of hours had passed, so they probably had obtained some results. In any case, they looked a bit beaten down, and it wasn't because Luke defeated them a few days ago.
"We have found one of the crystals inside a grove, it is being protected by hundreds of starving wolves."
"Good job, choose nine other parties to go there and finish the wolves and destroy the crystal," Luke said.
