I lead the way with Ruby behind me, I take her to the sewage treatment room, it's big and full of pipes and things to blow up. I take her to the center of the room and turn around to look at her.
"Okay, first I'm going to explain the fire beam spell to you to see if you can acquire the skill."
Ruby says "Okay!"
I then explain the spell to her step by step, how it works and what it feels like. She quickly understands and soon acquires the ability and shoots her first fire beam. It hits the pipe she was aiming at, but barely burns it.
"Okay, now I'm going to show you the blue fire beam."
Watch closely as a small blue fireball forms on the tip of my finger and then shoots out. It blows up a section of the pipe and melts it even more.
Ruby says "Wow, that's much more destructive!"
"Yes, but it's very complicated, you have to understand fire to a higher degree to evolve the skill."
Ruby says "Okay, I'll try my best."
