While I fully agree that the technique is completely ridiculous, I have no issues with you using it in this context. I'm a huge fan of "From hell's heart I stab at thee" moments, so feel free to make it such. Since I am unable to make any dice rolls to avoid losing dots I don't have, I'm going to go ahead and assume it's not going to kill or comatose Edmund. Severely wound in a permanent manner? Oh yes. Go right ahead Beta.
