Cosmic rune
“Used for enchant spells.”
About this item
The cosmic rune is a rune used primarily in enchanting spells. Enchanting spells enchant jewellery, such as rings and amulets, into something that has an effect when worn or operated. For example, when the player casts Lvl-4 Enchant on a diamond ring, the ring will become a ring of life. Cosmic runes are also used for the Lunar spells Astral Contact, Cure Me, Cure Group, and Spellbook Swap and for the resurrection spells in the Arceuus spellbook.

Its high alch value of 30 does not cover the 154 nature rune it would burn, so alching is a loss before the item itself is counted.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
