Introduction:
Jagex has released the Ouriana altar which has the ability to allow players to randomly craft any rune regardless of their RuneCrafting level.

Map + Key of the cave:

How to get there:
The shortest route is using the new teleport with Lunar magic which requires 2 astral runes, 1 law rune and 6 earth runes (magic level 71) to use and will teleport you to the entrance of the cave where the altar is located. For those who do not want or can not use that spell, the shortest way is to use a duel ring to teleport to the Castle Wars minigame and walk north past the Observatory to the chaos altar where you can catch red salamanders with the hunting skill. Another possibility is use of the Spirit tree at the Khazard battlefield (requires completion of the Tree Gnome Village quest).

Important points:

1. You enter the cave at this point and here you also have a bank owned by Eniola (see image). To use the bank you have to pay 20 runes of the same type (no difference is seen between e.g. earth runes or law runes).
   
   
   
   
   
   
2. The start of the long but safe route. There are no monsters to attack you so there is no need to use protective gear or prayers when using this route.
   
   
   
   
3. The start of the short but (somewhat) dangerous route. When walking here you will be attacked by the monsters that are there (not the crafters though). Running and Dragonhide armor recommended as it provides reasonable defence for medium weight. Prayer is highly advised for some players in less populated worlds because the monsters are aggressive and rangers can hit frequently if you are wearing Dragonhide. Prayer is optional in populated worlds since there will be lots of people running back and forth that the monsters will be attacking others rather than you all the time. It is recommended to turn auto-retaliate off as it makes your character run back to fight instead of running to the altar.
   
   
   
   
4. This is the altar where you can craft runes. The chance of getting better runes increases with your runecrafting level. All runes can be crafted here, from air runes to soul runes (not including any combination runes) The only type of essence that can be used is pure essence. You can NOT enchant tiaras at this altar.
   
   
   
   
5. At the end of the long route you have to pass through this crack to get to the Altar. There is no agility requirement for it and is only used as a barrier between the short route and any monsters managing to get to the altar.
   
   
   
   

Strategy:

- Lunar Teleport:
When using the lunar teleport to the altar it works best if you teleport to the altar with filled pouches, craft your runes and then use a teleport on a duel ring to bank at Castle Wars. Here you fill your pouches again and take up runes to teleport to the altar. (To activate the spell after completion of the Lunar Diplomacy quest you need to speak to Baba Yaga.)

- Banking at Eniola:
Pouches are not recommended when banking at Eniola as you have to bank 2-4 times using an extra 20-60 runes which you will not get back when crafting the extra essence. Instead, just fill up your inventory with pure essence and run to the altar to craft the runes. Optional is to take out a high number of runes you don't need anyway to make sure that you will have the 20 runes required to bank. You can recharge your prayer by climbing up the ladder and praying at the chaos altar next to the ladder.
