Depending on the method of travel, a round trip to the Cosmic Altar takes about a minute and a half to two minutes, including banking and filling up essence pouches. To start players must collect and pay for some scarred extract from the scar essence mine, collect them at a ratio of 1 per 61 aether catalyst.
Using the Slayer ring and fairy rings, you can make about 40 trips to the Cosmic Altar per hour. Start out at the Edgeville bank. Unload pure essence and store it in your pouches, and then take out essence for your inventory. Teleport via the slayer ring to Rellekka Slayer Caves, exit, and use the fairy ring to the west to teleport to Zanaris. From there, run south to the Agility shortcut; if you have 66 Agility, go through both of them, although you may get stuck and take a small amount of damage before passing through. Run further south and enter the mysterious ruins, and then go directly to the altar. Craft your essence in your inventory and pouches, and then teleport back to Edgeville with your amulet of glory or though player owned house.
Players with 80 Construction can use a fairy ring in their house for transport to Zanaris, in excess of 45 trips per hour are achievable when using this option. To begin the player will need to build a fairy ring, Lunar altar, and Revitalisation pool or greater in their POH; a basic jewellery box or greater is also useful but optional. Additionally, a rune pouch filled with air, astral, and cosmic runes will save inventory space. Once the runes have been crafted, use an equipped ring of dueling to bank at Castle Wars before casting Teleport to House and use your fairy ring to travel Zanaris, refilling run energy at your revitalisation pool as needed. The lunar altar will allow swapping to the Lunar spellbook briefly to cast Astral Contact when essence pouches need repairing, remember to switch back to the normal spellbook with the altar again afterwards.
Alternatively, a quest point cape or necklace of passage (Wizards' Tower teleport) can be used to access fairy rings after banking in Edgeville.
Note: Due to the large quantity of aether catalysts required for this method in conjunction with their buy limit of 25,000, you may need to wait for well over a day to be able to buy enough catalysts from the Grand Exchange in order to sustain just a couple of hours of making money with this method. This can be mitigated by buying the catalysts across multiple accounts or buying them directly from other players.
