If strategy not work just do unga bunga

Professor is a witch detected

What a stupid way to train kids. That dude teacher was right. You train the basics first, then move to more advanced stuff.

Only problem is with her leg, the artist forget that you support the twisted ankle not the healthy ones.

Seriously? She's failing to account for many things with that stupid assessment of hers. In real life you have many options: retreat, reinforcements, traps distractions, preparations with items, among many others, but right now they have only the option of killing it to pass.
If you want them to gain experience don't make the stakes so high, "BuT iN rEaL lIfE tHeY wOuLd DiE". They would get more options in real lif still

She's the "traitor" priest?!?

Fucking bitch.
Just kill the teachers if they keep trying to make things more difficult for your team, either keep things fair or you have to make it fair yourself by changing the teacher.
