Egg spawn scrolls are used by many players for their special ability that generates red spiders' eggs. Making these scrolls by using spirit spider pouches on an obelisk can be very profitable even at lower levels. To start off, buy spirit spider pouches on the Grand Exchange. They have a buying limit of 5,000 per four hours. To save money, find the lowest price that others are buying the pouches for, and put in an offer slightly lower than theirs. It will take longer to fulfil, but it will greatly increase the profit.
