The Ourania Altar.

The Ourania 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.

Originally released on 18 September 2007, the Ourania Altar was not included in Old School's initial launch because it was not a part of the game at the time of the 10 August 2007 backup of RuneScape the servers were based on. However, it was later revealed by the developers that the Altar existed in near-complete form in their archive, and in 2016 a Developer's Blog was written asking players if they wanted it released into the live game, offering some slight improvements compared to the original. After passing a subsequent poll, it was released on 13 October 2016.

The Ourania Altar converts pure essence into an assortment of random runes with a chance of bonus runes being created if players have the medium Ardougne Diary completed. The altar, which requires no talisman, tiara or staff to enter, gives 170% the normal experience for each pure essence used. Rune essence cannot be used. Players do not need a specific Runecraft level in order to craft at this altar, but the chance of crafting higher-levelled runes increases with a higher Runecraft level. Players can not craft a wrath rune through the Ourania Altar; this is the only rune uncraftable at the Altar outside of combination runes.

Inside the cave.

Once inside the Ourania Cave, quickly reached by an Ourania Teleport (from the lunar spellbook), players may use a bank there that requires a payment of 20 non combination 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.

After an update on 2 May 2019, players are no longer allowed to trade pure essence- noted or unnoted- to other players. Attempting to do so gives the message, You can't trade this item here. Players are also not able to pick up pure essence that is dropped by another player or dropped by a monster killed by another player while in the Ourania Cave, and attempting to do so gives the message, You can't take that - it doesn't seem to be yours. This update was done as players were able to obtain up to four times the polled experience rates through the use of runner accounts who would ferry essence to and from their bank.

## Mechanics

Players crafting runes at the Ourania Altar.

The player is able to craft all runes that are available in the game (except combination runes and wrath runes), despite not having the required level or quest requirements. However, the higher the player's Runecraft level, the higher-levelled the crafted runes will be. The experience here is 1.7 times what players would normally get for each pure essence.

Completion of the medium Ardougne Diary adds a chance of creating more runes in the Ourania Altar, though no extra experience is gained. The cloak does not need to be equipped for this to occur. The chance varies by rune, with the following estimates:

Rune Chance
Air 25%
Mind 25%
Water 25%
Earth 25%
Fire 25%
Body 25%
Cosmic 25%
Chaos 25%
Astral 25%
Nature 22.5%
Law 20%
Death 17.5%
Blood 15%
Soul 10%

When using Daeyalt essence at ZMI the experience is calculated as ${\displaystyle BaseXP*1.7*1.5}$

### Rune distribution

The distribution of runes given at the ZMI altar depends on your Runecraft level. There are separate distributions defined for each ten-level band: one for level 1 to 9, another for 10 to 19, 20 to 29, and so on. The following estimates are based on 6.7 million essence used. See the talk page for more details.

## Paths

There are two paths leading to the altar: a shorter, dangerous route, and a longer, safe route.

### Longer route

A section of the long path within the Ourania Cave.

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 (which has no Agility requirements) to reach the altar.

### Shorter route

The shorter route contains Zamorak warriors, mages, rangers and cave lizards, all of which are aggressive to players of any combat level. There are also Zamorak crafters, who are not aggressive to players above level 38, and will walk back and forth to Eniola. The warriors, mages and rangers often fight cave lizards when there are no players around. Higher level players wearing a combination of Magic and Melee armour can run through relatively unscathed. As this is a multicombat area, unprepared players can be rapidly damaged by multiple damage types by enemies with fast attacks.

## Method

The key is to wear weight-reducing clothing and some protection against the members of the Zamorak Magical Institute, who are aggressive and fight with all three styles. It is recommended to wear armour with Magic defence. Players can use Protect from Missiles and recharge Prayer at the altar by the ladder to the underground cave, this is convenient should players be using Ourania Teleport. Wearing a Hitpoints cape and regen bracelet can also help reduce the risk of needing food. A setup is shown to the right.

It is recommended to take the short path whilst playing on the designated Ourania Altar world, 327, which is often filled with other runecrafters running to the altar, causing damage to be spread across multiple players and, as such, protection prayers are rarely needed.

The Ourania Teleport is highly recommended for training at the Ourania Altar, teleporting players close to the entrance of the dungeon. Players can bank between runs either by using 20 runes at Eniola between runs, or by using another bank such as the Lunar Isle bank via Lunar isle teleport or at Castle Wars via ring of dueling teleport.

Rather than selecting the follow option, it is recommended to use an item on another player or to trade them as it will allow the player to follow them the entire way to the altar without getting trapped behind the walls.

## Experience rates

These are the estimated experience rates based on the developer's blog from 21 September 2016.

Data suggests that the chance of getting a specific rune changes based on level. However, the chance is the same for every 10 levels, i.e. the chance of getting a Death Rune is the exact same at level 30-39 but will increase significantly at level 40.

These experience rates assume players are using all of the pouches available at each level, and that the Ourania Teleport spell is being used. The actual experience rates received may differ. There is also an increase in experience when the player is able to use a new runecrafting pouch, for instance you have one at level 75.

You may additionally expect approximately 3k Magic xp/hr from casting Ourania Teleport.

Level Experience per hour Daeyalt Essence
1-9 18,658 27,987
10-19 20,916 31,374
20-29 21,817 32,725
30-39 23,064 34,596
40-49 27,109 40,663
50-59 32,126 48,189
60-69 32,508 48,762
70-79 34,802 52,203
80-89 43,917 65,875
90-98 46,186 69,279
99 46,885 70,327

## Banking

Eniola will allow players to access their bank in exchange for 20 of any one type of rune. Using inexpensive runes including elemental, body, and mind runes is common payment from players. Players can speak to him to set up a quick-payment deal, where they can choose which runes Eniola will automatically take from the player upon banking. He can take the payment runes from a rune pouch. Combination runes cannot be used in order to access the bank.

Usage of bank fillers is highly recommended with crafting runes at the Ourania Altar due to multiple runes being crafted and needing to be banked. This enables a player to have the ability to click the Deposit Inventory button without depositing any rune pouches or runes used to bank.

There are a few other methods of banking when training Runecraft at the Ourania Altar:

(update)
Trading essence within the Ourania caves was disabled to prevent experience rates reaching multiple times above the polled rates through the use of runners.

## Trivia

• 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.
• The Ourania Altar is one of a handful of vanilla content releases in Old School RuneScape that dates from after August 2007 but was able to be included with minimal development time due to it existing within the game's original archive. Other examples include the God Wars Dungeon (mostly finished due to its impending release in late August 2007) and the Smoke devil (an existing asset which was originally released as a Summoning familiar in 2008).
