First thing आप gotta do, is find an old gardening, sports, या construction tool that no one uses anymore, e.g., a shovel, baseball bat, lead pipe, etc.
Then आप gotta make it look और shitty than it already is द्वारा wrapping tape and या strings around it.
After that, आप gotta put some DIY mods on it to make it do और damage. For example, आप can put some spikes on your bat या put a bunch of rocks in an old pipe to make it heavier.
Once no one suspects the weapon of choice, आप can take out your target, but do it this exact way: Follow them, tap them on the shoulder, then when they look back, knock them out द्वारा hitting them as hard as आप can with your fist and या the club.
