Crystals
Rain took a good look at the human army before, and he knew that they didn't bring siege weapons. The reason for that was the fact that it was a slow way to win battles, but if a catapult didn't fire the massive boulder and make it cross their kilometers, what did it do?
"Unless it is some magic catapult that was assembled in a couple of hours, it wasn't such a tool that did that… it was a person or perhaps several," Rain thought while squinting his eyes. "They never stop surprising me."
The human army kept firing those massive boulders toward the camp. Rain was able to stop them midway until the magic people became ready to receive them. The water snipers bombarded them with their water spears, but it took a while for them to make the projectiles explode… the next explosions almost reached their camp, and the blasts destroyed their tents.
"It seems that only heavy things can make those explode…" Rain said while looking at Josar.
