Steel of legends scrolls provide an enormously powerful special attack for the steel titan, and they are often used while killing high-levelled monsters or in player killing. Because most players choose to buy these scrolls on the Grand Exchange instead of making them, there is lots of profit in turning steel titan pouches into scrolls. After you've made all of your scrolls, sell them on the Grand Exchange. Maximise your profit by buying one of the scrolls instantly, and selling yours for slightly more than that.
