The Ourania Runecrafting Altar (also known as the ZMI Altar) is one of the several Runecrafting altars located throughout RuneScape. The altar is in the Ourania Cave, which is west of the Battlefield, and south of West Ardougne.
The Ourania Altar converts pure essence into an assortment of random runes without a chance of bonus runes being created. The altar, which requires no talisman, tiara or staff to enter, gives double the normal experience for every rune crafted. Players do not need a specific Runecrafting level in order to craft at this altar, but the chance of crafting higher-levelled runes increases with a higher Runecrafting level.
Once inside the Ourania Cave, quickly reached by an Ourania Teleport, players may use a bank there that requires a payment of 20 runes of any type. They can then go to the altar by taking either a short and dangerous route or a longer and safe route. Note that the long, curving path has no monsters. At the end of the long path, there is a crack that requires no Agility level to cross.
- Casting Ourania Teleport requires 71 Magic, and places the player on the path to the altar entrance.
- Use Spirit trees to teleport from the Tree Gnome Village to the Battlefield and walk south-west.
- Cast Ardougne Teleport, requiring 51 Magic and Plague City, and head south-west.
- Teleport to the Ardougne Monastery with the Ardougne cloak 1, and walk north-west.
- Teleport to Castle Wars with the ring of duelling, and walk north from the lobby.
The player is able to craft all runes that are available in the game (except Armadyl runes and Combination runes), despite not having the required level or quest requirements. However, the higher the player's Runecrafting level, the higher-levelled the crafted runes will be. The experience here is double to what you would normally get for the runes.
Crafting runes at the Ourania Altar is the only known method of producing soul runes, as the equivalent altar may or may not be released into the game at a later date. The magic supply shops and the Grand Exchange are still the dominant supply for these runes.
The Ardougne cloak 2 (and higher) adds a chance of creating more runes in the Ourania Altar (rune output is increased by roughly 15%), though no extra experience is gained. Master Runecrafter robes (the full set gives 5% more experience) will work here. However, they have a maximum boost of 700 experience per altar click or batch. Runecrafting gloves from Fist of Guthix will not work here, as the experience is already doubled.
There are two paths leading to the altar: a shorter, dangerous route, and a longer, safe route.
This route is a long winding pathway. Once players reach the end of the path, they will have to squeeze through a small crack in the wall to reach the altar. The wall-crack shortcut has no Agility requirements.
The shorter route contains Zamorak warriors, Zamorak mages, Zamorak rangers, Zamorak crafters, and cave lizards. The warriors, mages and rangers often fight cave lizards. Players with a combat level of 110 or below will probably want to take the alternate route, but higher level players will be able to wear a combination of Magic and melee armour and run through relatively unscathed.
The key is to stay light and protect against the members of the Zamorak Magical Institute, who are aggressive and fight with all three styles, it is recommended to wear armour that boosts Defence against Magic, and activate Protect from Missiles. Here is a list of a recommended setup with downgradeable options:
|Slot||Item (most effective → least effective)|
|Mighty slayer helmet||Armadyl helmet||Royal d'hide coif||Black d'hide coif||N/A|
|Amulet of fury||Amulet of glory||Amulet of defence||Holy symbol||N/A|
|Ardougne cloak 2 or higher||Any Cape of Accomplishment||Spottier cape||Spotted cape||Obsidian cape|
|Agile top||Wicked robe top||Armadyl chestplate||Royal d'hide body||Black d'hide body|
|Agile legs||Wicked legs||Armadyl chainskirt||Royal d'hide chaps||Black d'hide chaps|
|Any Ranged shield||Void knight deflector||Falador shield 3 or 4||Blessed spirit shield||N/A|
|Penance gloves||Regen bracelet||Barrows gloves||N/A||N/A|
|Boots of lightness||Spined boots||Carapace boots||Snakeskin boots||N/A|
|Ring of life||Explorer's ring 4||N/A||N/A||N/A|
Eniola will allow you access to your bank account in exchange for 20 of any one type of rune. Using runes which are common, or not often used, such as body runes, or elemental runes, is the smarter economical decision. Currently, the cheapest runes are Earth runes or Water Runes at 14 and 16 a piece respectively. Due to an update, you no longer need to close the bank window to fill Runecrafting pouches with pure essence.
The full bank method is very common and highly recommended with crafting runes at the Ourania Altar due to multiple runes being crafted. This enables a player to have the ability to click the Deposit Inventory button without depositing any rune pouches or runes used to bank.
Items such as vegetable sacks and fruit baskets may be used to fill a player’s bank fully. Other items include robes from Canifis and Rellekka, strung and unstrung short and longbows, variety of bolts and arrows, and rewards from Stealing Creation such as metamorphic and volatile tools. Vegetable sacks and fruit baskets with different amounts of fruit in them allow the player the player to expand and compress bank space at ease, making it more convenient for the player. (This avoids having to drop junk items.)
There are a few other methods of banking when Runecrafting at the Ourania Altar:
- Teleport up and down between Lunar Isle (Home Teleport or Moonclan Teleport) and the Ourania Altar (Ourania Teleport). Tele Group Moonclan tends to land the player a few squares closer to the bank than Moonclan Teleport.
- Use the TokKul-Zo to teleport to any of the three "Fight" options and the Ourania Teleport spell to return to the cave. This is just as close to a bank as the Castle Wars teleport but does not use any charges on the ring.
- The ring of kinship will teleport to Daemonheim and has unlimited charges.
- The ring of duelling will teleport to the Castle Wars lobby.
- Use the games necklace to teleport to the Burthorpe Troll Invasion area and the Ourania Teleport spell to return to the altar. This is marginally cheaper than the ring of duelling, and just as efficient since the Loyalty Programme update placed a bank outside the Warriors' Guild.
- Ourania (Ουρανία), or Urania, was the muse of astronomy in Greek mythology (the name means "heavenly" or "of heaven" in Ancient Greek). This is significant considering the proximity of the grave of the astronomer Scorpius and the Observatory.
