most people use a candle. most usually if you want to cause harm, it's a black candle. light it, watch the flame and think evil thoughts about your enemy
Around my neck - Errrr no thanks. lol I hope I don't have enemies. Although reverse psychology works also, no need for candles. lol
there is another....you take a picture of your enemy and wrap the chicken feet with the pic, then bury it at a crossroads. your victim and all his family is supposed to fall to ruin....slowly.
ok last one. if you can get a piece of clothing from someone, like a shirt, slip it inside a shirt of you own. they are supposed to stay close to you forever.
chicken feet are fun. tie a string to the tendons and when you pull, the feet will curl up like they are grabbing something
I know that one. Also if you throw money into your house then leave for a while, it is supposed to bring wealth. But every spell has a downside.
