Have too much Snow Fall ink laying around?
I use mine to make Runescroll of Fortitude. 1 Snowfall Ink and 5 Resilient Parchment makes 5 scrolls. On my server I can sell Runescroll of Fortitude for 3-5g each. This allows me to (after parchment costs) pocket about 15g after ah fees per ink.
I typically list them on the ah in stacks of 5, 10, and 20.
Don’t have excess ink? Another trick I use is buy some when it gets as low as 6-7g each on the ah and double my money in a day or two.
