Law runes are usually the runes created by Runecrafters from levels 65 to 99, or 92 if they want to go back and make some profit along the way. Law runes have two designated worlds for rune running, which are worlds 66 and 99. Each world usually has a separate Runecrafting clan in it, with some straggling solo Runecrafters there to just get experience and not in a Runecrafting clan.
Running Law runes is the most profitable and main source of income for many people on Runescape, as it is the most profitable way to make money running runes. The only bad part about it is that the altar is located on Entrana, an island you have to take boat to from Port Sarim located south of Falador or west of Draynor Village.
To run Law runes in the most efficient way, I would suggest running the runes from Falador to Port Sarim and take the boat to Entrana. Once you’re at Entrana, run east and then north, cross a bridge and you will end up at the Law altar at the north-eastern tip of Entrana. Once you trade the pure essence for Law runes, teleport back to Falador with a tele-tab or teleport runes. Since you’re going to get Law runes, all you really have to bring is 3 airs and 1 water rune to be able to teleport back to Falador. Once in Falador, repeat the process over and over, until you have as much money as you need.
Air Runes
Like mentioned in the "Air Runes" part of this guide on page 2, you need to run Air runes for someone with a higher level Runecrafting to get more for your money. Since many people move on to Nature runes at 44, you want to find someone at least level 33 Runecrafting to run runes for. If you run 28 rune essence per trip to a level 33 Runecrafter, you should receive 112 Air runes per trip. Currently, rune essence costs 39 gp each and Air runes are 11 gp each.
Cost: 28 rune essence x 39 gp = 1,092 gp per trip
Money Earned: 112 Air runes x 11 gp = 1,232 gp per trip
Profit Per Trip: 1,232 - 1,092 = 140 gp per trip
140 coins for 2 minutes of work isn't too bad for someone with 2k coins in their bank. However, if you have more money, like around 100k+ to buy pure essence with to run Nature or Law runes, I would suggest doing that instead because of the better profitability.
On the next page, we'll talk about how much profit can be made from running Nature and Law runes.
