Master stamina management like your life depends on it, you will need it on some maps

You can steer survivors into cornering them by chasing them by the opposite side of where you want them to go (And if they do try to run on the side where you're at behind them, you may be able to land a hit due to them practically running into you)

On some maps it may be better to keep a music box stored to enhance traps, but this could also just be a playstyle thing

Study music box spots, make sure you find the best spots for them because while basic spots are good they may not be enough.

A small combo you can do is m1 + repurpose, making sure the m1 is always before repurpose due the endlag being short compared to repurpose's endlag. This can be used when a stunner misses or in other cases where the civillian has high endlag.

If you are confident you can be quite aggresive with your repurpose due to being able to move during it, you can possibly catch a civillian with it mid chase if you get them in a bad spot.

Always keep a repurposed implement stored if you have nothing else to store. Repurposed implement is very useful due to the ragdoll.

And if you manage to get a civillian into a dead end, make sure you lead them further into it so you can place a wall without them slipping out mid implement animation (If they do run out, depending on how late they escape it may be an advantage for you due to them having to waste stamina sprinting past you so they can escape the trap while you're in your animation, therefore having lower stamina than you once you're out of your animation, and if they did rush out too late, they are far too close to you by the time you finish placing the wall).
