Here are the four steps of success (and they do not even involve placing anything unhygienic under your pillow!):
1. Enter the most sacred and do your duty on the altar. Do not worry about the size or the quality of your sacrifice, Fecal Fairy is understanding and doesn't discriminate.
2. If you happened to be a cunning one, you may now escape through the doorway you left open to maintain a quick escape route. Close the door afterwards for safety measures.
3. ???? Do whatever you want, live like every day could be your last. It's best not to think about the progress, doing that may jinx it.
4. Collect your part of the trade from the sink after a day or two, 'cause as you know: many sacrificers equals plenty of work. Hence, patience truly is a virtue. There's no shame in wearing a gas mask, real men use protection. The final sum may vary, but average payment is around 4 euros for each solid piece. Switching to Uzi fire- mode is banned by international fecal trade laws.
