You trade 2k and 25 noted ess for 25 unnoted ess. You than craft the ess into air runes. It will take you 11,130 ess to complete. 11130/25(ess per runner)=556.5~557(runners total). That 557 runners, so 557*2000ea=1,114,000gp. At the end, you will have 39475 air runes. 39475(airs)*20(gp each**)=789,500gp. 789,500-1,114,000=-324,500. You will be down 324,500gp if you use this method, not to mension(sp?) the time this will take and you must pay the runners before you sell the runes. Im also assuming that you are mining your own runes. To buy them, it will be another 333,900 at 30ea. I suggest NOT doing this, but following the lines of runners (*free taxi*) to the alter. Thats my way of doing it, and try multitasking...it helps aid bordom. Anyway, runecrafting is the hardest skill be good at, but pays great at high levels. Bombpie **20gp ea for airs is a high peice, but some people will buy. 15 is more likely.
