OSRS: ZMI/Ourania Runecrafting Guide!
ZMI altar just came out today in osrs! Make sure you're on the lunar spellbook with ourania teleport unlocked, and bring at least 20 runes. Maximum efficiency is supposed to be 46k xp/hr. Having the medium ardougne diary tasks complete gives you bonus runes as well (no bonus xp).
Hope this was able to help you out and good luck with the runecrafting gainz!
Thanks so much for watching!
