Early game
Lunar Diplomacy
Unlock the Lunar spellbook with powerful utility spells
Completing Lunar Diplomacy unlocks the Lunar spellbook, which offers powerful utility and skilling spells like Plank Make, Superglass Make, and Spellbook Swap. These spells are useful for both skilling efficiency and flexible magic use.
You'll also gain access to the Astral Altar on Lunar Isle, allowing you to craft Astral runes — essential for casting Lunar spells.
Lunar Diplomacy is also a requirement for the midgame quest While Guthix Sleeps, which is one of the mid game goals later on in our guide.
