Sapphire

Rohan, Having thought out his choice over a few seconds looked down at the ring before returning his gaze to his teacher and pressing down on the blue gem. The Gem locked into place and gave a light gentle glow before fading, the gem stayed locked in place. It wasn't until rohan had looked away from his teacher that the ring released the sapphire allowing it to be pressed again only for it to spring back. ' Interesting ' He thought to himself before looking back up to see his teacher having stopped talking and now holding her head in her hands groaning in pain. "Class dismissed, I just got a random headache, if you have any question about the lecture please see me during my office hours later in the week" She called out to the class, which none seemed to ask any questions and happy to be let out early for once.

Rohan Kept a smirk to himself before joining the rest of the class in leaving the classroom though he slow to leave, just looking at his phone pretending to read something and scroll. in reality he was just buying time to see the effects of the ring take effect on his target. He wanted to see the effects take action and what excatly happened to Miss Felix. She couldn't to hold her head in her hands until he had left with the rest of the class.

"I had forgotten to mention the time it takes for the changes to occur, it takes a day for any real change to be seen" The ominous voice had conveniently chimed in with. "that would have been nice to know a head of time" He replied in his head careful to not speak allowed in fear of people calling him crazy for talking to himself.

Finding Nothing else to do and no errands needing to be ran he went home for the rest of the day
