What that much essence is worth from your current level, with the setup on the left.
Every figure is an average. Each essence becomes one rune picked at random, so a short session can land either side of these numbers and a long one settles on them. Experience an hour uses the trip time you set and takes off 15 seconds an hour for each size of pouch that needs repairing. A figure with a ~ is an estimate: stamina potions at one four-dose potion to 325 essence, and a pouch repair each time the pouch that wears out soonest is due. Runes sell at the instant-sell price less the 2% tax, which takes nothing from a rune under 50 coins. Daeyalt essence cannot be bought, so it costs nothing here and the time spent mining it is not counted. Figures checked against the OSRS Wiki on 21 September 2026.
ZMI experience and rune chances by level
The Ourania Altar, which most players call ZMI, has no level requirement. Each pure or daeyalt essence becomes one rune, and which rune depends on your Runecraft level in bands of ten levels, with 99 a band of its own. The altar pays 1.7 times the rune's usual experience, and daeyalt essence half as much again on top.
| Level | Air to body | Cosmic to astral | Nature to death | Blood | Soul | XP each | Daeyalt |
|---|---|---|---|---|---|---|---|
| 1 to 9 | 97.5% | 1.9% | 0.53% | 0.05% | 0.02% | 9.39 | 14.08 |
| 10 to 19 | 96% | 3.15% | 0.76% | 0.06% | 0.03% | 10.52 | 15.79 |
| 20 to 29 | 83.5% | 14.3% | 1.97% | 0.15% | 0.08% | 11.34 | 17.01 |
| 30 to 39 | 60% | 35% | 4.4% | 0.4% | 0.2% | 12.27 | 18.40 |
| 40 to 49 | 45% | 45% | 8.8% | 0.8% | 0.4% | 12.90 | 19.35 |
| 50 to 59 | 37.5% | 36% | 24% | 1.7% | 0.8% | 13.47 | 20.21 |
| 60 to 69 | 35.5% | 34% | 27.5% | 2% | 1% | 13.63 | 20.45 |
| 70 to 79 | 22% | 28% | 43% | 5% | 2% | 14.59 | 21.89 |
| 80 to 89 | 22% | 25.5% | 42.5% | 6% | 4% | 14.82 | 22.23 |
| 90 to 98 | 16% | 23% | 44.5% | 10% | 6.5% | 15.35 | 23.02 |
| 99 | 14% | 20.5% | 43.5% | 13% | 9% | 15.58 | 23.37 |
Blood and soul runes go from 1 essence in 33 at level 60 to more than 1 in 5 at 99. The calculator lists all fourteen runes at your own level.
Essence a trip
With a rune pouch in one slot, a trip is 29 essence with a small pouch, 34 from level 25 with a medium pouch, 42 from 50 with a large pouch and 53 from 75 with a giant pouch. A colossal pouch holds the same as the pouches it is made from until level 85, where it holds 40 and a trip becomes 66. At 48 seconds a trip that is about 77,000 experience an hour at 99 with pure essence and about 115,700 with daeyalt.
More runes, the same experience
The medium Ardougne Diary is a chance of a second rune: 1 in 4 for every rune up to astral, 22.5% for nature, 20% for law, 17.5% for death, 15% for blood and 10% for soul. Each piece of the Raiments of the Eye adds 10% more runes and the full set 60%. An abyssal lantern adds 5% with willow or redwood logs, 10% with magic logs and 20% more blood runes with blisterwood logs. None of them adds experience.
Banking and getting there
Eniola opens your bank inside the cave for 20 runes of any one kind, so the cheapest rune on the Grand Exchange is the one to bring. Ourania Teleport needs 71 Magic and Lunar Diplomacy and costs a law rune and two astral runes with a dust battlestaff. Astral Contact repairs pouches from anywhere for an astral and a cosmic rune. A Runecraft cape, a max cape or redwood logs in an abyssal lantern stop pouches wearing out at all. Worlds 327 and 480 are the official ZMI worlds, where the short path is safer in a crowd.
ZMI questions
Is daeyalt essence worth it? It is half as much experience again for every essence, and it has to be mined at 60 Mining after Sins of the Father. The side by side table shows the hours it saves on your own goal.
