Focusing on efficiency
Once everyone ate and began to feel relaxed, Rain told them that they would start training. For starters, made everyone use the four elements and that had been relatively easy for that squad since they were good at controlling their mana.
After creating some elemental spheres, Rain made them summon walls made of earth, water, wind and fire. Things began to change a bit at that moment. Some of them were able to do it soon, but some others couldn't at all.
"Fifty people isn't a large number, but I will have to make it do," Rain thought. "Agaisnt large number of enemies, we won't need that much support from them, so I guess it will be fine to split them in four groups."
After doing a few more tests, Rain split everyone according to the element that they were better at. That was the creation of the fire squad, water squad, wind squad, and earth squad.
