The Soul Altar is a Runecrafting altar that is found in the Imperial district in Menaphos. It can only be accessed upon completion of 'Phite Club. It is used to craft soul runes from pure essence at level 90 Runecrafting.
As with most other Runecrafting altars, it can be accessed via the Abyss. Players can only enter its ruins by using a soul talisman. Players could also simply click on the ruins while wearing a soul tiara, omni-tiara, a wicked hood (imbued with a soul talisman), an omni-talisman staff, or a soul talisman staff, only after the Soul Altar has been unlocked.
The Soul Altar is located beneath the water fountain in the Imperial district. The water can be drained by clicking "Fill" and causing the soul talisman to drain the water, allowing access to the stairs and underground passage which lead to the altar. After this, the wicked hood and abyss can be used to access the altar.
The mechanics of crafting soul runes vastly differ from the standard Runecrafting process. The altar must first be charged with pure essence by putting pure essence into the 'charger'. Four essences generate one charge and give 10 Runecrafting experience. This takes five seconds to create. 1.25 charges create one soul rune. This means it takes 5 essences to make one soul rune. The experience gained is 220 per charge or 275 per soul rune crafted.
The 'Charger' has a capacity of 100 essences, after which they must be converted into charges; and the altar can hold up to 100 charges, after which they must be crafted as runes.
To maximise the experience gained, the 250% bonus experience of abyss rune crafting (thus the Demonic Skull too) is applicable to the runecrafting step. A maximum of 77,000 experience can be gained by binding a fully charged altar into at least 80 soul runes.
Bonus experience is not applicable on the charge converting step.
A soul tiara may be created at this altar by using a soul talisman on a normal tiara in the player's inventory. The player must use the tiara on the altar. Doing so will earn 55 Runecrafting experience.
- Upon release, it was mistakenly stated to require level 90 Invention in the Skill training guides to use rather than level 90 Runecrafting.
