We need to do something nasty to Ment. Deprive him of his endgame ability, or his skills, or block him somehow, or something else.
Because of you, the keymaster was killed, and now you want to completely ruin the game. Maybe the archer came to you for a reason?
At least explain the point. What do you think of us? As a Reaper, or something else? Let's say the first. A wizard visited me today, and what interesting endgame ability did he use on me? I think it's not hard to guess if he shares the same views. Okay, what makes the Reaper dangerous, more than anyone else, especially after the wizard's turn? And I'm interested in how you plan to get rid of Camelia. The Mortis will die, and then what? It's obvious that you need to get rid of her first, otherwise you won't be able to do anything to her later.
You're hammering nails into your own coffin.
