Earth Altar

The Earth altar may be found northeast of Varrock and south of the Lumber Yard. It is used to craft Earth runes from rune essence or pure essence, providing 6.5 Runecrafting experience.

Access

As with most other runecrafting altars, it can be accessed via the Abyss. Players could also enter its ruins by using an earth talisman, an Elemental talisman, or an Omni-talisman. Players could also simply click on the ruins while wearing an earth tiara, Omni-tiara, a wicked hood imbued with any of the above, an Omni-talisman staff, or an earth talisman staff.

Currently, the fastest way to get there is to used the Wicked hood's teleport, which could only be used 2 times, or 3 if all the Wicked robes have been purchased from the Runespan. The second fastest way is to break an earth altar teleport tablet. Both of these methods teleport the player just outside of the altar. The wicked hood can be obtained by talking to Tam McGrubor, and the teleport tablets by playing the Great Orb Project.

Experience

The maximum likely limit for crafting Earth runes in one visit is 1,012. This would be achieved by having 78 Runecrafting, giving a 4x bonus, and carrying 253 essence to craft (23 in the normal inventory along with 48 in the 5 sizes of Runecrafting pouches, along with 175 claimed from the wicked hood (if all the Wicked robes have been purchased, and 7 from any abyssal summoning creature), whilst wearing an explorer's ring (which has a 1 in 10 chance of producing an extra rune per essence). The maximum possible experience is 3,289 obtained doing the above while wearing Earth runecrafting gloves.

Combination Runes

It is possible to make Mud runes, Dust runes, and Lava runes while at this altar, but at a lower success rate. This will result in less runes than normal being made. To make a combination rune, the player needs one set of elemental runes, a stack of pure essence, and 2 talismans.

To make...	You need...
To make...	Talisman	Rune	Essence
Mud runes	Water talisman	Water runes	Pure essence
Dust runes	Air talisman	Air runes
Lava runes	Fire talisman	Fire runes

If the player equips a Binding necklace, the success rate will increase to 100%. It has a total of 15 uses before breaking. A charge is used each time a combination rune is used, instead of each time the altar is entered.

Tiaras

An earth tiara may be created at this altar by having an earth talisman and a normal tiara in your inventory. The player must use the tiara on the altar. Doing so will earn 32.5 Runecrafting experience.
