Mechiel's training focused on wielding and controlling water. She now had the power to command water and freely move it. Kyros had taught her and allowed her to train in this. But the foundation of Mechiel's water spell was actually another power that the Blood Calamity already had.
Her power to command blood was passed on to the water. And by using the Corruption of Charm, the element of water was pulled and tamed along with her blood. Mechiel had to go through a lot of training, and ultimately, her current form could control the most waters that she had.
