What I expect this thread to be - "i have a knife/gun/x so i kill him from behind"
What would happen in real life - "i have a knife/gun/x but cant do stuff and either freeze, hide, run or get taken hostage/killed"
Though since it is all fantasy I have a collection of knives in my room so I boobytrap my door (because i can obv do that (with magic)) and he dies the end.
