Crafting mud runes
|Pure essence, water or earth runes, water talismans or earth talismans, binding necklaces, amulet of glory, stamina potions, runecraft pouches, a pickaxe|
|Enter the Abyss for access to the Abyss|
|D'hide armor to protect from PKers, or weight reducing clothing to reduce energy usage|
|Inputs (233,728.75)||Outputs (822,925)|
|2,000 × Pure essence (4,000)2,000 × Water rune (8,000)7.5 × Stamina potion(4) (52,260)6.25 × Binding necklace (5,456.25)100 × Water talisman (16,100)12.5 × Amulet of glory(4) (147,912.5)||2,000 × Mud rune (676,000)12.5 × Amulet of glory (146,925)|
The above rates are calculated assuming use of the small, medium, and large pouches for 40 Pure Essence per inventory. Rates will be slightly lower without the pouches, and slightly higher with the giant pouch.
This method requires the Enter the Abyss quest for access to the Abyss. At average speed, one can do about 50 trips to the Earth altar via the Abyss per hour, using the amulet of glory to teleport back to Edgeville, and using an equipped pickaxe to mine through the rocks in the Abyss. You need to recharge your pouches every nine trips (depending on pouches used), at the Dark mage, to prevent the pouches from degrading. A Binding necklace is needed to ensure that all of the combination runes are crafted.
The Mage of Zamorak is located low-level Wilderness, near the source of the River Lum. This is a fairly safe area, but there might be player killers, so it is advised not to take expensive items on the trips to the Abyss. The best setup would be cheap but protective gear (e.g. dragonhides). Use of weight-reducing clothing is also recommended. Falador shield can be useful to negate the loss when killed by a player, as it can recharge prayer instantly (once or twice per day) which can be used to activate Protect Item. Use of abyssal bracelet is optional, but is ultimately too expensive to be worth using. Inside the Abyss, the creatures there will be aggressive and might do fair amounts of damage, along with Prayer being drained to 0 upon entering the Abyss. See Abyss#Inside the Abyss for more information on how to navigate the Abyss. Once inside, enter the earth rift and craft mud runes by using the Water talismans on the altar. Teleport back to Edgeville and repeat the process.
