Location of the Cosmic altar
Strange fairy symbols found at the Cosmic rune altar.
As with most other runecrafting altars, it can be accessed via the Abyss. Players could also enter its ruins in southern Zanaris by using a cosmic talisman. Players could also simply click on the ruins while wearing a cosmic tiara.
There are two agility shortcuts that allow faster access, one requiring 46 Agility for the medium shortcut, and 66 Agility for the advanced shortcut. You will take four damage if you fail these shortcuts.

Crafting 1 essence into a cosmic rune grants 8 experience.
From level 59 on (boostable) there are 2 cosmics created per essence, without giving any additional experience.
This is required for the Lumbridge & Draynor Diary hard task of creating 56 cosmic runes simultaneously.
A cosmic tiara may be created at this altar by having a cosmic talisman and a tiara in the player's inventory. The player must use the tiara on the altar; doing so gives 40 Runecraft experience.
- When a player enters the altar, they are randomly sent to one of the four portals inside.
- The projectiles that fly throughout the altar resemble Wind Blast.
